Get into precharged guns at an unheard-of price and also get the accuracy of an expensive European rifle! Benjamin has bridged the gap and taken the pain out of PCP guns. Not only is this as low a price as you'll ever find on a PCP rifle, but it's so easy to pump up that a wispy teenager could do it! The Discovery has raised the bar for PCP guns because it uses only 2000 psi of air. While the European companies race toward higher and higher air pressures- Benjamin is going the opposite direction and making it easier than ever to use a hand pump. If you want to use a scuba tank or carbon fiber tank, you can do that too and get the benefit of many more fills than you would from a gun that operates with 3000 psi. The Discovery gives you a choice! The air reservoir is 135cc. The air tank has a male Foster fitting. The gun comes with a hardwood stock, Williams fiber optic front and rear sights and a built-in air pressure gauge. When you open your box, you'll see easy-to-follow and easy-to-understand instructions that'll lead you step-by-step. If you're an experienced PCP user, you'll soon see that the Discovery is the easiest PCP you've ever used. If you're new to PCPs, you'll become a pro in just a few short steps. If you want to switch to CO2, that's easy to do, but you'll need a degasser tool to quickly exhaust all the air before filling with CO2. Attach the optional CO2 adapter, connect it to a standard paintball CO2 tank and fill 'er up! Now commence to shootin'! With high-pressure air you'll get up to 25 powerful shots. This version of the Discovery does not include a pump- tank- yoke or fill adapter. To connect your Discovery to a scuba tank- you'll need a scuba tank adapter with hose and a female quick-disconnect with male threads. The tank must have a K valve. To exhaust air or CO2 from the rifle- you need to purchase the degasser tool.

I got this one for Christmas a few years ago from father-in-law and it has been one of my best pesting rifles it has lots of power and accuracy this is a very fun rifle

Lots of power good accuracy well made

No regulator small Reservoir it is a bit loud not backyard friendly for sound

By DarrellUSASeptember 7, 2017

What a deal! Big $$$ off for taking a chance on a refurbished rifle. I am here to tell you, it was perfect. I can not detect a single flaw. The bluing is clean, the stock is very nice and it shoots great! I might Not have baught my Marauder if I had purchased this rifle first. No, that's not true. It's not a Marauder. But after replacing the crummy trigger with a Marauder one and a couple mods, it shoots just as nice. It's very lite even after adding a lite scope and sling. I already have a compressor, tank and hand pump. But it's so easy to hand pump, you don't really need to invest a lot of coin to have a lot of fun.

It's lite! It' inexpensive! And it shoots way better than a $200 air rifle aught to!

As any one who has owned a Disco would and do say, the trigger sucks. A $50 drop- in Marauder trigger makes this issue vanish. The company could add the good trigger. They could add sling swivels. They could .......But it wouldn't be as inexpensive for a starter PCP.

By Bruce O.August 21, 2017

Gun was like new except for a small scuff on the stock. Would do business again.

By CarltonUSAMarch 27, 2017

Like the Maximus the Discovery does not disappoint. Added a TKO muzzle brake which offers a couple levels to the quiet factor. Sure makes it more back yard friendly. Wood stock with the same accuracy as the Maximum. Fill to desired level with air tank or easily with hand pump. Nice looking and shooting PCP. No complaints, delivers to advertised specs. AD fast and well packaged delivery. . . .good service.

Accuracy, nice wood and balance, muzzle brake adaptable, hard hitting.

Not necessarily a con more of a comment. . . . .Marauder type mag would step it up a notch but the cost as well.

By SimonUSAMarch 6, 2017

Benjamin discovery .22 is a little gun with big power, it just little too loud for backyard shooting.

By DeannaUSAJanuary 23, 2017

I Bought my Discovery from AGD a while ago on sale, couldn't be happier with my purchase. Have a 3-9x40 scope on it, at 25 yards with Predator Polymag pellets I can punch them in the same hole every time.

High quality like most everything AGD sells Tack driver all the way, same hole performance

no, notta, NONE!

By GabrielUSADecember 9, 2016

This is an awesome air rifle. The fit and finish are second to none. The wood stock is beautiful. The gun is lightweight and a great brush gun. I have harvested a few squirrels this year with it. The rifle is zeroed in and was a one shot kill at just over 35 yards. If you are thinking about buying this rifle, don't hesitate. You wont be disappointed.

Accurate, Lightweight and powerful.


By GregUSASeptember 3, 2016

A Discovery in .22 was my first PCP. Accurate, light weight, easy to cock, and harder hitting than most .22 springers and a big jump up from CO2. The gun is pellet picky. Groups at 20 yards can very from 1/4" to several inches depending on pellet selection. It is an easy enough gun to pump up by hand, but I added a tank within a month of getting the gun. The trigger responds well to the 2 screw addition trigger mod. It is not a repeater. But is easy enough to load. Love the wood stock. Every Benjamin Discovery I have bought leaks. But they respond well to a couple of drops of pure silicone oil in the fill valve. A great way to get into PCP guns. I also have 2 of these in .177. They are great rabbit and ground squirrel guns. The Crossman Brown Box 10.5 grain pellets are deadly accurate in these guns.

Light weight Cost Accurate

Leaks Trigger

By BernieUSAAugust 11, 2016

Would have given 5 stars but the first one I received would not hold air. This gun is accurate very accurate, I have hit birds at 100 yards. It does take roughly 100 pumps to fill the air tank but I am getting 25-35 shots.

Very powerful Accurate and reliable


By Sgt.FaganUSAJuly 4, 2016

I've had other duel fuel rifles and PCPs, but this one is a Crosman...Benjamin and is top notch. The 2000psi makes small game hunting and varmint hunting a breeze, plus being able to use both air and C02. I just take another 12 0z tank with me, and I'm good for another fast fill, 30 good shots; and the 12 oz will fill it at least 8 times. Perfect field rifle, great power and wonderful accuracy! Not that heavy and not too light, so there's not much muzzle shake when aiming.

Quick filling, 30 rounds per fill. Great construction, balanced weight and a de-gassing system. Duel fuel is a huge plus to its power and accuracy. If you also hunt small and medium game, and/or varmint shoot: this is a great rifle for a low price.

The plastic or polymer trigger: I know to keep the cost down on a high end PCP rifle, some things need to be done, so I understand. Same with the barrel, could be shrouded but, is still quieter than my .22 LR, and ammo is MUCH cheaper. Still a great hunting rifle, regardless. The butt plate could be rubber, but not a big deal...has no recoil. I have no issues with it performance wise. Overall: I don't see how/why a metal trigger couldn't be installed.

what is he best and cheapest way to air or co2 up a benjamin.? I now have a been. break bbl.. g. h.

asked gene from USA

Is this gun manufactured in the USA as claimed in the promotional video?

asked Mark

what does the dual fuel mean??

asked terry

With the purchase of a low cost adaptor, you can power the discovery off of Co2 rather than high pressure air. You can switch between the two propellants as long as you make sure you completely empty the tank of one before adding the other. You will get a lot more shots using Co2, but with less power (fps and fps). The use of Co2 is for use in warmer conditions as it does not work well in colder conditions. Check out the YouTube video reviews by places such as air gun web where they explain this in detail. I hope this helps. The discovery is a really sweet air rifle at twice the price.

William from USA

Dual fuel means that you can use either CO² or compressed air on the rifle

Clayton Tatenda from Zimbabwe

In regards to this rifle dual fuel means that it operates off of compressed air. This rifle holds up to 2000 psi. That allows you to fill the rifle and shoot as many shots as you can until you run low on air pressure. This is the better way to shoot this weapon. The other "fuel" for this rifle is co2. You probably have seen the smaller less potent guns that use a small co2 container to give the force to shoot your ammo (bb's or pellets usually). This rifle can also be used to run off of co2 but you more than likely will not get the power out of it that you will with the air pressure. With the co2 you will get a certain amount of shots and then you will run out of co2 and have to throw the co2 cartridge away. They can't be refilled (that I know of) plus they generally are not too powerful. Hope that answered your question. Benjamin makes a great air rifle and I would not hesitate to buy a refurbished air rifle from them. Good luck and be safe.

Tommy D

You can use compressed air with a hpa tank or a pump and you can use co2


"Dual Fuel" means that the rifle can be charged, either with High Pressure Air ("HPA") or CO2. For HPA, you need a specialized pump ($190 - $290) which looks like a bicycle pump but which is capable of producing pressures as high as 300 PSI. Alternatively, scuba-type tanks can be used to fill the air chamber. For CO2 "fuel", an adapter is required, which allows you to fill the reservoir from a bulk, refillable paint ball tank. HPA produces more muzzle energy but is significantly louder than CO2 and shot count is lower.

Kenneth from USA

"Dual Fuel" means that the Benjamin Discovery can run on either High Pressure Air or CO2. WARNING: Do NOT use both at the same time. When going from one to the other (HPA to CO2 or CO2 to HPA) you must purge the gun completely before switching to a different gas. Also, the HPA and CO2 run at different fill pressures. You can see the two respective fill ranges labeled on the fill gauge.

Edward from USA

Dual fuel means that the air rifle can be filled with high pressure air at 2000 psi or carbon dioxide (at a lower pressure).

William from USA

The rifle can use either high pressure air or CO2 for a propellent. It will lose significant power on CO2 because it is a much lower pressure (2000 psi vs. 800 psi for CO2).


1. can this gun be left charged, or partially charged, or must all the air be drained after use. 2. what is the longest time it can be left charged without damage 3. do you have silencers for this rifle, so i may practice shooting in a suburban back yard?

asked marcelo

It can be left fully charged and even cocked for any amount of time. This does not hurt the rifle in any way. No you cannot legally purchase a silencer for this gun.. With that being said TKO ldc's will probably interest you. Legality questionable but effective.

Clint from USA

Yes the gun can and should be left charged . It's good for the seals so leave it charged . My gun has been in storage for about a year now and I left it charged with air and periodically I check on it and I'm happy to say the rifle hasn't lost an ounce of air .. For your second question check out YouTube for the silencer that goes nicely with the rifle ...


How many pumps with hand pump does it take to get 200 psi

asked Timothy Greene

I believe you meant 2,000 psi, which is the gun's maximum fill. It does indeed take a good number of pumps to go from 0 to 2,000 psi, but when you shoot, you only run the gun down to 1,000 psi. For me, it takes about 50-60 pumps to go back up to 2,000 psi from 1,000.

Ron from USA

with my hand pump it's about 115 to 120, its a good warm up on a cold winter morning hunt

Timothy from USA

with my hand pump it's about 115 to 120, its a good warm up on a cold winter morning hunt

Timothy from USA

When is this gun available?

asked Sean Gabs

Sean, Unfortunately, when it comes to refurbished items we really do not have a time frame of when we might see more in stock. It could be a few weeks to months. Just depends on when the manufacturer has when we order. Hopefully that answers your question. Sincerely, Airgun Depot Customer Care Team

Scott from USA

I want this gun badly but then I read one last review with a person stating the end of the barrel is unsupported!.......I have heard that the end of the barrel is not attached to the large pressure cylinder. It is attached half way back down the barrel leaving 12+ inches of unsupported 3/8 inch brass tubing. (in-which brass is very soft) This seems like a vulnerability, to get bent at sometime or another no matter how careful one might be. Is this not a concern and why would engineering leave this tiny thin brass barrel unsupported. dncook

asked david from USA

The barrel and pressure cylinder are attached in front of the stock. This gun is well built takes abuse and stays shot in. Had 17. caliper for 2 years. Impressed enough that this year i got the .22 cal.... There is no brass in this gun. Pressure cylinder is made of same steel as the gun barrel.

andrew from USA

It's a floating barrel supported at the breach and by the mid band. It was designed that way for accuracy. They do It's the same thing as to a firearm when they bed the barrel in the stock (it's really not touching the stock at all) it's floating about .005 or more above and is only supported by the one bolt that holds the gun to the stock below the action. If this was a huge problem all these years they would have changed it for sales sake alone. The Discovery has a history of being a wonderful rugged, accurate lightweight rifle, especially at the low price !. You can find comments from people who pick things apart but have no experience with the actual product. I have 2 Discoveries and so does my buddy who is very rough with his guns and he and his wife love them both ! If I knew what I know now their would be a lot less break barrels in my collection. Buy one, you'll be impressed !

Arnold from USA

David, I wouldn't let the unsupported barrel stop you. I've gone into the field with mine several times and never run into problems bending the barrel. You can also have another band added by a professional tuner. My only (minor) caution about the Discovery is the trigger is perhaps a little stiff. That, too, can be adjusted by a tuner. I have yet to put in a trigger mod and have bagged several squirrels with my Disco. You might also look into an after-market muzzle break that will tone down the gun's report. That will be more delicate than your barrel, and I still haven't had a problem with mine. Ken in GA


hello I'm dhiaa from Iraq ,can ship this item to Iraq???

asked dhiaa

Dhiaa, Please contact our International Shipping Department at [email protected] They can answer any questions you might have. Sincerely, The Airgun Depot Customer Care Team

Scott from USA

If you purchase the gun w/o the pump how can you shoot it? Is there a price for the pump separately? Also, what is the price for the CO2 adapter?

asked Bill

Hi! Will you ship in Russia ?

asked Yanis

Yanis, Please contact our International Shipping Department at [email protected] They can answer any questions you might have. Sincerely, The Airgun Depot Customer Care Team

Scott from USA

Can it be pumped with auto pump?

asked Alex from USA

Can a scope be mounted on this gun?

asked jack

Yes you can mount a scope on the weaver rail of this rifle. Take into consideration that you need to load your pellets for each shot and will want to use scope rings of medium or high design to have room to load each pellet. I use high rings and a 4 - 24 x 50 AO scope which works out very well. I hope this helps you out with your rifle. This discovery is an awesome rifle at twice the price. I love mine, and I have a large collection that cost hundreds more.

William from USA

Yes you will need to install medium to high scope rings so you have room to load the pellet in the breech.

henry from USA

Yes and easy to install.

henry from USA

Yes, a scope can be mounted to the Benjamin Discovery. It has a dove tail mount milled in the receiver, same as most .22 LR. rifles. This is my Discovery with a Hawke 2.5-10 x 44 Varmint scope using BLK standard mounts. I have it mounted a bit forward for eye relief, but there is dove tail on both sides of the breach.

Edward from USA

definately yes.

austin from USA

Yes, check out this link (from, which is a pretty good review of the rifle:

Lucius from USA

Yes, a scope can be mounted on this gun. The receiver is slotted for the weaver style mounts, just like a .22 caliber firearm . You will need a two piece, high mount. The loading slot is small, and a higher mount makes loading much easier. Also, a one piece mount will tend to block the loading slot or breach, and restrict positioning the scope to the front or back as needed for the shooter. OldRoy

Dale from USA

Can this rifle use CO2?

asked pedro l from USA

Can you fill this Benjamin gun from a nail gun compressor? If not how much is the hand pump? Thanks Mark

asked Mark from USA

No, it has to be filled to 2000psi. A nail gun compressor would not do it, nor would a bike pump. The benjamin pcp pump is $179. If you want a good deal on walmart(dot)com its $330 for the pump and the gun.


Hello sir. How may I purchase the .22 airgun?

asked rajasekar

Hello! Send them this or other articles to Austria? If so, how much is the shipping to Austria, please? Best Regards, Erich P.

asked Erich Papacek

Thank you for you interest. For questions about international ordering/shipping please email us at [email protected] This so we can better help you.

Steve from USA

Whats a good scope and mount for this gun?

asked Ryan

My .22 Disco has a 3-9x50MM Centerpoint scope on it. My only point here is that the 50mm objective just barely fits even using high mounts and at that, I had to remove the rear on-barrel sight. I suggest that folks use something with a smaller objective, such as a 40mm or 32mm scope. 50mm is about the largest you can fit onto a Disco.

Joe from USA

I have big fingers so, I chose the high rings, It gives me plenty of room to load the pellets. I also like the 4-16 X 40mm Center point scope I purchased with it.. A lot of folks seem to like the Leapers scopes too.
