Description
The SIG Sauer MCX Rattler CO2 BB Rifle has many similarities to the successful short-barreled rifle firearm line that inspired it. It reaches velocities up to 300 FPS for excellent performance for target practice or plinking.
This BB rifle features a minimalist folding stock that is reminiscent of the one from its powder-burning counterpart, making it easy to transport and store due to its compact size with the stock folded. The pistol grip uses a combination of texturing on the sides and ridges on the front and rear that makes it nearly identical to the grip used on the firearm version.
The SIG MCX Rattler utilizes a drop free magazine with a capacity of 30 BBs to provide extended shooting time, and the selector switch goes from safe, to semi-auto, to 3-round burst to deliver an exciting experience without wasting ammo. This BB gun uses a 12-gram CO2 cartridge for power and has ambidextrous controls to accommodate both left-handed and right-handed shooters.
The long Picatinny optics rail for this air gun holds both the included flip-up front sight and the flip-up rear sight to enable accurate shots out of the box, as well as allowing shooters to add a scope or dot sight. In addition, the handguard offers M-LOK T-slots that help to securely and easily attach accessories such as lasers and lights.
To get an airgun that takes its design cues from the renowned family of SBR firearms, buy a SIG Sauer MCX Rattler CO2 BB Rifle from Pyramyd AIR now.
Tech Tip: The safety can only be engaged when the rifle is cocked, like the real steel version. Attempting to force the safety "on" without the rifle being cocked may damage the airgun.

REAL JUNK!
Things I Would Have ChangedThis CO2 gun has an extremely limited life because the gas seals in the receiver where the magazine connects are junk! After so many recharges with a new gas cartridge the seals wear out and all your gas leaks out! I know it's not the magazine because I tried a new one and same thing happens.
What Others Should KnowIf you're determined to buy one I recommend getting a protection plan, for whatever it's worth. SIG should stick to making real weapons, which are probably just as worthless!
First things first, this airgun is very well made. Although the plastic on some parts may be prone to damage (charging handle, flip up sights, and stock). One big problem is that the accessories on this airgun is not (kinda) compatible with other Sig airgun accessories (other airgun handguards). Some Amazing features on this airgun are: slide locking back on last round, Not being able to put back on safe after dry fire, great blowback, YOU CAN FIELD STRIP IT, (internal) gas blowback, the magazine not looking horrible (pmag 🤩🤩🤩) folding stock, the stock not looking horrible, working small features (bolt release and assist, ambi mag release) WORKING SLING QD (only on stock....). Some very bad things about this airgun are: plastic handguard, non working handguard sling QD, flimsy and wobbly charging handle (also plastic), so light that the magazine is heavier when the gun is bare bones, non working sling QD near fire selector. The absolute best feature(s) on this gun for me is the godteir trigger, 3 round burst(I forgot the metion) and charging handle+working bolt. DO NOT! absolutely do not rack the charging handle too hard, it will literally snap.
Works good, do not overfill magazine. Great for shredding boxes.
The looks
Things I Would Have ChangedEverything that has to do with its actual functioning
What Others Should KnowFirst 2 magazines jammed up. used a different ammo brand for 3rd magazine which also jammed up and magazine leaked out air as well. Tried another brand ammo, made it about 5 shots before air escaped from the seals somewhere coming violently out of the upper receiver. THE GUN LITERALLY BLEW UP IN MY HANDS. RETURNED THIS JUNK
The realism of this air rifle/pistol is outstanding. It’s polymer construction is “Tight, and Solid”. Full upper rail is scope or optics ready.
Things I Would Have ChangedGive it more FPS, as the current power leaves a Lot to be desired. The detachable magazine is cool, but loading is tedious, and slightly difficult.
What Others Should KnowThe “flash hider/muzzle break” is non-removable for those individuals who like to “dress-up” their airguns. Also, the rear AR/M4 style bolt is functional, but not quite sure what it actually does. The grip is the only thing that can be replaced (the equipped grip is Ugly but very comfortable for myself. The price may seem a bit high, but the fun with this gun on auto* is totally worth it! BTW this gun has a 3 round burst mode, a semi-auto, and safety. If your looking for a plinker, then this may be for you!
I like the overall design. Feels solid. Easy trigger pull.
Things I Would Have ChangedRedesign of the magazine. And have spare mags available to purchase.
What Others Should KnowThe one I currently have is a replacement. The first one broke internally after the first 3 bbs. I limmediately contacted Pyramydair and arranged for a replacement, which I received in about a week.
I'm having a little issue with the magazine. It has to be really tightened down hard for it to not leak co2. The bb follower spring does alway push the bbs up into firing position, even after I lubed the spring and the channel. Still the majority of time it will not work properly. The bolt catch on the mag doesn't come up and catch the bolt on the last shot like it's designed to do. And I am unable to to find replacement magazines anywhere online. And I hesitate to return the 2nd gun back just for a somewhat minor magazine issue.
This is a very well made airgun. Hefty and sturdy. A blast to shoot
Things I Would Have ChangedSpare magazines. There are no spare magazines available yet. So, use care when ejecting the mag. It breaks, you'll have a big paperweight. Make sure when introducing a new model, have spare mags available for purchase.
What Others Should KnowSig and Umarex need to make sure additional mags are available. For now, mine will be put away until the mags are added for sale. Normally, I don't buy a new model unless spare mags are available but, I wanted the Rattler for my Sig Sauer Collection.
I like feel and the weight, plus it's FUN.
Things I Would Have ChangedNothing
What Others Should KnowGet one
Accuracy at 10 yards is plenty fine for what it is. The 3 shot burst is just as much fun as full auto on other guns. 12 gram Co2 operation is a welcome thing since some of us only have a half-hour to get out and plink, where an 88 gram or 90 gram would be too much for such a small window. The magazine is really easy to load with a follower that locks back, the Co2 chamber has a built in turn key so you won't need to fumble around with a separate allen key. A HUGE plus there! It's very easy to field strip, just be careful not to lose your spring upon taking it down. Handles and feels identical to it's modern firearm counterpart. It does lock back on last shot which is great. Some of these SBR style airguns do not and you end up wasting Co2. This is not the case here.
Things I Would Have ChangedThe folding stock is a very durable polymer, but I would have liked to see that made in aluminum instead. Of course this keeps the cost down. Still, very durable and only a minor gripe. Also, I would have liked to see the ejection port actually functional as it is on Crosman's DPMS. Again, only a minor gripe that doesn't affect your experience.
What Others Should KnowDon't forget your eye protection, the bb's will be flying with this one folks! Great fun!
