The SIG Sauer MCX Rattler is a CO2 BB rifle that gives you a similar look and feel to the firearm version of this popular SBR. You get velocities up to 300 fps for fun and exciting backyard plinking or target shooting.

You'll enjoy the fact that you get more time to shoot with less time reloading because of the 30 round drop free magazine that mimics the capacity of the real steel version. Plus, it has a selector so you can flip it from safe, to semi auto, to 3 round burst, giving you the options you need for thrilling fun without using all your ammo.

You'll find the SIG MCX Rattler simple to store and move because it comes with a minimalist folding stock that's very similar to the one on the original firearm version, making it compact when folded. Both right handed and left handed shooters will find it easy to use because it has ambidextrous controls, and you'll appreciate the 12 gram CO2 cartridge that gives you straightforward and reliable performance.

You can add your preferred dot sight or scope to the long Picatinny scope rail, or use the attached flip up front sight and flip up rear sight to get accurate shots without extra equipment. It's also fast and easy to attach accessories like lasers and lights securely with the M-LOK T-slots on the handguard.

If you're in the market for a CO2 BB rifle that lets you experience the excitement of the enjoyable SBR platform without the noise and expense of the firearm version, get a SIG Sauer MCX Rattler at Airgun Depot today.

Please Note: This rifle's safety functions like the real firearm, it can only be engaged after the rifle is cocked. Attempting to force the safety into the engaged position without cocking the rifle first may damage your airgun.

By Kelvin Prevost October 1, 2023 Verified Purchase

Love the mcx rifles I own them all but the latest mcx rattler keep failing right out the box gonna send back and try again hopefully this stay with my collection really like gun I wanna shot it not look at it

By EdgarAugust 1, 2023

I recommend the .22 pdf version of the Sig with extra belts. There are now some very reliable compact PCP pumps on the market at reasonable prices ( naturally Chinese made! ) Edgar G., PhD Prof. Emeritus Mech. &Aerospace Eng.

I have 2 .177 co2 Sigs and 2 .22 pdf Sigs. The Sigs are unique in that they are belt fed. I currently have 26 air rifles from brake action, co2 and pdf in .177, .22, and .25. The Sigs are all fitted with green lasers. They might not be the most accurate of my air rifles , but they top the list of most fun to shoot .

Care must be used in fully inserting pellets in the belt.

Mimics firearm version, select fire, magazine weight, quality steel sights, fun, fun, fun!

Gas hog if shoot bursts too quickly as it chills the CO2 canister.

By Joseph USAApril 8, 2023 Verified Purchase

If you’re into replicas, this is the one to purchase

I like the way that I like the feel and how it handles

I wouldn’t change anything

By Joseph USAMarch 24, 2023 Verified Purchase

It’s a lot of fun just spraying and shooting and having a good time with it

I got mine Thursday I’ve already shot 4000 rounds through it shoots Fallis get a lot of mags out of a CO2 cartridge on semi you get 90 shots and on burst you probably get 60

I wouldn’t change a thing for what it is
