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.

The looks
Things I would have changed:Everything that has to do with its actual functioning
What others should know:First 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
Got a question or answer?
Log in to participate
Is the length in the specifications with the stock extended or folded?
Is this the same folding brace found on Sig’s real guns ? Will I be able to take off and attach it to a real sig gun?
Does the Rattler have real QD mounts?

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.
