Awesome BB gun. The main reason why you want to buy this gun, is the fact that it fully customizable. The rifle being all metal is also great.

I do wish though that it had blowback and higher ammo count.

It looks like a real gun and is powerful

Make it a Bit bigger

By DaveApril 5, 2020

I made a simple box of ABS plastic card to slip over the Mag it has a funnel shape inside and all you have to do is put the follower on lock back and then fill the box with bb,s and rock it back and forwards gently and the mag fills in secionds

All metal receiver and barrel accuracy is quite good

Mag loading method

Personally I really liked this airgun. Very accurate and a blast to shoot. Loading the clip is a bit of a pain, but worth the fun. However mine just quit working out of the blue. Airgun Depot made good and sent me a replacement. So we'll see

Very accurate. Blast to shoot.

Tad hard to load. Quit shooting and had to have it replaced in a short time of use

I’ve set my hellboy up with a quadrail front hand gaurd,tac light, scope, buttstock pad,cheek pad, and a comfort grip. Great gun for plinking and pest control. I recommend getting a co2 gasket to put around the co2 piercing needle as it limits the co2 loss during cartridge exchanges. Other then that minor detail I love the hellboy and all its ability to MOD.

Fully modifiable, powerful, accurate, and realistic!

Needs a gasket to help prevent co2 loss during cartridge install.

I have grand kids that are going to learn how to shoot. I want them to be familiar with the "Black Gun" right up front. It's important to pass on our skills and heritage. I have the good fortune to have a place to shoot but it's really handy to just step out in the back yard for a little inexpensive fun. It's great for dry fire. I would recommend this rifle to friends.

Reasonable price realistic function all metal reasonably accurate

co2 leakage when installing cartridge. elevation on rear sight will creep when adjusting aperture.

By JoeUSASeptember 22, 2018

The first one I received was a dud and as the same day AGD received it back they shipped me a good one. Craig handled my RMA I think. This gun not getting into exact measurements is a great replica of what has been the AR platform issued across most of the U.S. Service . It has the look and fell. You can separate the upper and lower by tapping out the pin. The charging handle is just for looks. I do recommend opening the Dust cover when firing for in the rare incident of a BB jam. They are easier to un-jam when there is a place the BB's to go. The Sling Swivels hooks are cool. I also found that it will attach an M7 Bayonet. My M9 will not fit over the muzzle break. The gun bayonet sattachment doesn't match the exact M4 attachment I am familiar with What the gun consists of is a double action trigger striker, the Magazine where everything happens and a nice long steel barrel for a BB gun Now for shooting I don't have an chronograph so I don't know the real speed. Using mine on Days in the Low 80's F It is piercing steel coffee cans and Bush Baked bean cans at 10 – 20 yards. I have most always get 8 full mags out of a co2 cartridge and it runs out of gas. So that is 144 shots. Although you have to single drop the rounds in it is friendlier that other guns built to single drop the BB's only into . If you have all your fingers and decent dexterity that is nothing to write home about.

accurate hard-hitting efficient on co2 good for cheap practice and you don't need to use “ears� with this in your back yard

It would be cooler in a larger magazine capacity once I am really in the zone knocking targets away at targets its time to reload. Again I can refill the mag in approximatly minute. No big deal.

By BrandonUSAAugust 12, 2018

So I bought this just for a little project I was doing to see if I could use it as a training rifle... Turns out it was a great purchase. I added a real m4 quad-rail, it was kind of difficult to get on, but it fits and is solid, so I went with a SOPMOD Block 1 setup. I added a rugged mock combat ACOG, AN/PEQ-15, Bipod, crane stock, sling, 1-point stock mount ring, foregrip, and mock suppressor. It is about a pound lighter than the real SOPMOD kit, (there's no buffer or spring so that's why its lighter), but it is freaking amazing and solid to use as a training rifle. Minus the lack of a functioning "bolt carrier" and bolt release. It hit a way higher expectation for me than what I initially expected. Love it so far.

Like I said, its about a pound or more lighter than the real deal with my SOPMOD setup, and it also is pretty light out of the box. -No mock bolt functions. -The pistol grip is NOT compatable with any real AR pistol grips, only the one it comes with.

By NatanielUSAJuly 20, 2018

This BB gun is really fun , very accurate and decent range.

Does it come with the mag

asked Filippos from Canada

Now, so does the magpul pistol grips work or not? Because the reviews say they don’t but I always see people using them? Can someone explain please.

asked Jacob from USA

Is this gun full auto?

asked Matthew from USA

No unfortunately this gun says full auto, yet when you switch it will stay in semi

Jacob from USA

where do u find the customized parts?

asked Bean from USA

Literally anywhere thats sells m4/ar15 parts, the hand guard is carbine length btw

Jacob from USA

What is the company that makes these, cause I wanna ask them somethin about the bb guns they sell? Also where would u get parts for this bb gun.

asked Bean from USA

The company that makes them is Air Venturi and you can buy parts literally anywhere that sells m4/ar 15 parts

Jacob from USA

Hi. I want to replace the handguard for a quadrail picatinny. Where can i get one please ?


Christopher from USA

I'm curious, how is the CO2 pressure maintained while reloading? I'm from the Old School, so I don't know how a pierced Powerlet won't simply go "Shooooish" once the "magazine/cylinder" is removed.

asked Robert M Darden

The firing mechanism that that CO2 is housed in has a cap that only when trigger pulls will release CO2. Hard to explain but there is a mechanism in place.

Christopher from USA

Excuse me for asking this, but I'm curious how the CO2 Powerlet doesn't lose pressure when the magazine is withdrawn from the gun? In all the CO2-powered air guns I have, you'd have an immediate "air out," losing what remaining pressure you had.

asked Bob

3medium noise level is compaired to what ?



Christopher from USA

Hi, This is a great airgun, but just wondering about the handguard, I wanted to replace it with a drop in quadrail, I tried the AIM sports already but it does not fit in the delta ring, Can you suggest any brand of quadrail that I can get without doing any modification or machining? Is the delta ring on this gun differs from the standard somehow? I would appreciate any advise. Many thanks. Julius

asked Julius

I added The AIM quad rail to my Hellboy with out any issues. The Delta ring is mil stock meaning same diameter as real M4. Only thing on this rifle that isnt true milstock is buffer tube. Its about 1/1/2m less diameter than real M4.

Christopher from USA

Hom many bbs can it hold and what is the distance
