Utilizing a 13 cubic inch 3000 psi air cylinder with a regulated output of 1100 psi, you can rely on up to 150 consistent shots. Capable of speeds up to 700 FPS, from it's 30 round magazine as fast as you can pull the trigger! With up to 11 FPE of power, the MCX Virtus is equally at home on the range shooting targets and in the field going after small game. Zero in on your intended target with the included flip up sights, or take advantage of the full length picatinny rail and mount the optic of your choice. The rifled 17.5" barrel is housed in a M-LOK™ handgaurd, for easy mounting of a multitude of accessories.

This weapon is very close to working the same way a real AR functions. I am completely astounded by the quality of the weapon in total

Lack of working dust cover.

By JessUSAApril 19, 2021 Verified Purchase

an 1800psi regulater puts it at 700fps

part 2 review. I had a problem with my gun, returned it under warranty and recieved a new one. what a differance . this one is accurate!! well worth the purchase.

By JoeUSAMarch 17, 2021

Love this gun it my sons favorite and I own 6 air rifles mostly by hatsan and I am starting to love this one the most because with 39 rounds you can have a real blast and 22 is big enough to actually get things done from a weapon that looks like a true assault weapon finally somebody had balls to make a assault style air gun ...!!!! Thank you Sig Sauer ???????????????????? Ten hearts ??

Most realistic assault style rifle you can buy and as a 22 caliber it hits a metal target long n hard (( 30 times )) ...!!!

None ;))

By AaronUSAJanuary 24, 2021 Verified Purchase

The gun is very fun to shoot.Looks great.30 round belt is fantastic, I don't have to reload every 12 shots.I am getting 150 shots from 3000psi down to 1000.I have a small backyard about 20 yards (60 ft) so this gun is perfect.I put a Sightmark LoPro mini green laser on it so I can plink at night. My wife loves it! I also put a UTG red/green circle dot sight on it with a First Strike floating stock to cover the tank.If you want to just plink and have fun that's what this gun is made for.

Nothing I can think of.

By KarlUSAJanuary 23, 2021 Verified Purchase

I would not buy this gun again and will be looking to see if there is something I can do with the warranty.

Comfortable design

Constantly jamming which makes the clip very difficult to remove. No consistency even at 2800-3000 PSI

By GreggJanuary 22, 2021 Verified Purchase

Got it originally to get the kids comfortable with AR platform. It’s so similar that now I have a 6yr. old girl who can load & fire an AR! More similarities than expected! Almost identical weight, put in mag & charge it with charging handle behind the carry handle, etc. saw review saying it was junk but guy must’ve got a lemon & should exchange. Mine shoots 1” groups at 50yds. Seems to have impressive fpe.

Comfortable and familiar to shoot. Great for target practice & all around fun. Operates perfectly. M-lok is a great system. Put a bipod on there for the kids.

Could use a spare mag. Would be super cool if dust cover opened

By JessUSADecember 14, 2020 Verified Purchase

For the price ill give it a try, try a higher regulator. my final thought / instead of making a bad ass replica they should of made a bad ass gun. - J.M.

30 rounds semi auto. Hits hard enough to take rats

Accuracy is poor. maybe its the pellets im using but atleast i have 29 more tries to hit that rodent. The non functioning aesthetics, why? just leave it off.

By FrederickUSADecember 9, 2020 Verified Purchase

Overall I love shooting this pellet gun in my back yard or any where targets real accurate added a different site didn't like the ones on it had to turn the gun side way

love how quick the tank fills and thirty shoots just like that stunning looks and feel like the real deal.

boost the speed on the pellets up around 1000fps add a bipod would be nice

By TravisUSASeptember 14, 2020 Verified Purchase

I cannot for the life of me understand why Sig Sauer put their name on this thing, I have 3 Sig powder burners and they are all amazing so I expected something other than terrible with this. I have lot of airguns and this is by far the worst one I have ever purchased. I would hope AD would let me return it as defective as poorly as it functions but not holding my breath. Unless you are planning to shoot 10 yrds you really need to look at something else.

The magazine works well but that is the only pro about this gun..

The gun shoots over 1 foot group at 50yds. Trigger is horrible but I could live with it if it shot well.

By JessieUSAAugust 28, 2020 Verified Purchase

Works perfect

Tanks a little heavy

What kind a hand pump will work with this gun?

asked Cadyn from USA

Can you please let me know the ideal hand pump or compressor to fill the air tank on my new .22 Sig SauerMCX virtus ? Thank you

asked Sean C from USA

Is this set up to use regular pellets? Can i use slugs. Or do I have to purchase a kit? for the sig. to shoot slugs like the FX?

asked Thomas from USA

Spare magazines I'll buy 10 if you produce them

asked Thomas from USA

They will be coming soon.

Cadyn from USA

Could I attach a 100 CU 4500 psi carbon fiber tank directly to the receiver to replace the little one that is already on it I clearly understand the weight and difference yeah yeah I want to know if the receiver is going to blow up in my face as soon as I screw the bottle in I kind of already have my mind made up but I'm not going to purchase this with that tiny tank I'm just saying and do you sell aftermarket clips for this thing I want as many mags as I can get my hands on ????

asked Thomas from USA

Do you need to degas this Sig before removing the tank and if so, how? I prefer to store it with the tank removed (but full).

asked Donald from USA

What is the best ammo for this rifle?

asked Troy from USA

How do you filll that air tank up. Can you use my air compressor from my shop or do I have to go somewhere or buy a new one or what

asked Aaron from USA

Can't use regular compressor must be High pressure I love my nomad 2 by Air Venturi but something similar would be fine heard good things about the Umarex compressor but I dont know from personal experience an HPA handpump will work also and it comes with a free gym membership.

Joseph from USA

Is there a barrel exchange kit for this gun. I'd like to see the barrel at half the length.

asked Jason from USA

do you need a foid car to bye this in Illinois

asked Dani from USA


Val from USA

Can I use a bike pump to pump the tank? And how many pumps. Thank you

asked Mark from USA

No. Can't reach high enough pressure to fill it.

Stephen from USA

Would this item be able to take down snakes?

asked Daniel from USA

Easily. I'd say your good up to medium RODENTS.

Salvatore from USA

I have shop air at 150 psi can I refill my own cylinder?

asked Michael from USA


Brian from USA

No it requires 3000psi

Donavan from USA

Can you fill this guns tank with a Regular aircompresser

asked Phillip from USA

Nope need a 3000-4500 psi compressor

Brian from USA

No it requires 3000psi not your standard 120-150psi

Donavan from USA

Spare Mags available?

asked Jon from USA


Donald from USA

Is the tank co2 or air?

asked Paul from USA


Brian from USA

Air its the same as a scuba tank

Donavan from USA

If I want to avoid the appearance of intent, can I have a moderator adapter welded to the barrel of this rifle, so that it couldn't be used on a firearm, or would welding the adapter on ruin/warp the barrel?

asked Lane from USA

Can you fill the bottles with a regular air compressor

asked Jerry from Canada

No,it needs to be filled with a special compressor, hand pump or air tank. Regular air compressors do not have to high capacity PSI.

Steven from USA

Can you recommend a good hand pump for this rifle?

asked Michael from USA


Donald from USA

Can you leave the tank attached to the gun to fill it? Or should you remove the tank then fill?

asked Justin from USA

The tank can be left on the gun to fill.

Todd from USA

You may leave the tank attached to the rifle while filling it.

Robert from USA

Yes, you can leave it attaced.

Tim from USA

Can you prefill bottles, and swap them in the gun?

asked Sean from USA


Robert from USA

Mine stopped working! Any idea who I have to contact?

asked Mark from USA

If it is in the first 60 days of the purchase air gun Depot will work with you. After the 60 days you go directly to Sign.

Steven from USA

Dose Sig have a hand pump that goes with this tank, or do you sell a hand pump you would recommend to go with this airgun?

asked Richard from USA

Sig is currently designing their own hand pump that should be released by the end of 2020. That being said there are many different hand pumps from many different manufacturers that would work with this rifle. Just be sure it has a 1/8th quick disconnect.

Robert from USA

Any of the hand pumps will fit the Sig Virtus.

Mark from USA

Where do I purchase the moderator Also do you know what's Scope fits

asked Martin from USA

In the aftermarket silencer /moderator Donny fl is a awesome company and a great product. Check them out!

Todd from USA

Donnyfl for moderator but you will need a custom made adapter to fit the 1/2 x 20 of the mod to the 1/2 x 28 threads of the barrel. Check there web site. I should mention not to have the adapter ANYWHERE near an actual firearm with 28 tpi threaded barrel. A jury will see this as INTENT to use on firearm.

Tim from USA

Any scope with a weaver base will fit, A noderator is an aftermarket item.

Mark from USA

Will this kill a rabbit/mouse/squirrel? It says small game hunting but I would like to verify. Also, can I put a can on the end to decrease noise? Or is the noise not from muzzle?

asked wade from USA

At 10-35 feet It should be lethal.It is not a high powered airgun. The barrel is threaded.

Mark from USA

Where is it made?

asked Robert from USA

Mine says japan

Tim from USA

mine says made in japan

Salvatore from USA


Mark from USA

Can you ship out to other country ?

asked Danh from Vietnam

That depends on the import laws of the destination country. We do not know all of the rules. That is the customer's responsibility.

Mark from USA

Could this be run from an external tank and a connecting hose?

asked Kim from USA


Mark from USA

Is the barrel threaded? If so, what thread pitch?

asked Mikayla from USA

1/2 x 28

Tim from USA

moderator that fits on my hatsan fits on virtus.

Salvatore from USA

The barrel end is threaded. We don't know and do not have any to check. Contact Sig Sauer for that info.

Mark from USA

Can you purchase extra magazines for the gun?

asked Luke from USA

ebay has extra magazine with 3 belts( 30 rounds) and 500 pellets for 60.00

Salvatore from USA

At this time we do not have any extra magazines. You can contact Sig Sauer. They may have some. 603-610-3000

Mark from USA

Is there a hand pump I can order with it? I have read Sig will be coming out with one soon, but on this site is there one?

asked Bryan from USA

Any hand pump will fill the Victus.

Mark from USA

Are there any slugs you would recommend for this one (I hope I don't start to sound like a broken record, as I will probably ask that about a few other guns in the next few days).

asked John from USA

it is a .22 cal. sig sauer venom 14.5 grain pellets come with the extra mag kit. sold separately.

Salvatore from USA

Any slug will be way too heavy for the Virtus. You want to shoot a pellet of between 7-10 gr. Waddcutter or hollow points.

Mark from USA

Air tank included?

asked Ronan from USA


Mark from USA

Good morning, have you had any problems with the magazine loading ammo into the chamber. Thank you for your time.

asked Rafael from USA

Mags work perfectly as long as the tip of the pellet doesn't stick out of the end of the belt after you seat the pellet with the included pellet seater. Those Gamo rocket red tipped pellets and similar ones will give you issues. Once I stopped using those I rarely had a jam and when I did it was because occasionally a pellet would be slightly smaller for some reason and it would poke out the end when it came time for that pellet to be fired. I've had great success with the hybrid fx .22 slugs they fit snug and hit hard and are a blast when shooting the air venturi exploding golf balls just make sure you have a secure backstop no matter what ammo you choose.

Joseph from USA

mags work great

Salvatore from USA

Yes. There have been magazine issues with the Virtus. Contact Sig Sauer.

Mark from USA

what else do i need to get started ? i do have a compressor ... can i refill the tank with my compressor ?

asked Lawrence from USA

Hello, can someone please tell me if the barrel is threaded and if so what is the size? Thank you for your time
