Decimate soda cans and shred paper targets with the SIG Sauer MPX!

Based on the gas-operated submachine gun of the same name, this MPX runs on 88 or 90-gram CO2 cartridges to send shots downrange at speeds up to 575 fps. Each MPX includes a 30rd rotary-belt pellet magazine and a rifled barrel to increase the accuracy in fast-paced tactical shooting sessions.

Packed with realistic controls and specs, the MPX exudes all things tactical with its all-metal action, durable polymer stock and forend, and a long Weaver Picatinny rail. The included adjustable flip-up sights are removable, and the rifle really begs for a dot-sight for even faster target acquisition. A tri-rail surrounds the barrel and features a lower rail, and 2 side rails with small Weaver mounts for attaching accessories like flashlights and lasers. Each includes sling mounts for easy carrying to and from the range (sling not included).

If you want a one-of-a-kind fast-paced shooting experience that only SIG Sauer can provide, the MPX is sure to give fans of target shredding hours of backyard shooting fun for years to come.

Verified Purchase

Things I liked: Excellent gun to practice marksmanship with- very easy to use(loading, firing,etc), very accurate, and it looks really cool, too. I LOVE this gun! I also have the Sig MCX, but this firearm is even better because of its size. It is also easy to accessorize with all the rails on it. Five stars, definitely.

Things I would have changed: I would like to see a bigger magazine (40-50 rounds)

What others should know: Make sure you use the pellet seating tool to avoid pellets falling out of the rotary belt.

Things I liked: EVERYTHING!! The Feel The Look The Action!!! Great Gun one of my very favorites. Right out of the box I knew this gun was special. I shot 180 rounds with 88gr. CO2 cartridge at 15 yards No jams No problems. Would not peirce tin can but I am still checking out dif pellets I used destroyer and excite copper so far.

Things I would have changed: Nothing, its good to go as is. Weight, look and feel are all so realistic It rates right up there with my best airguns.

What others should know: Long ago I ordered the .22 cal version which never came. Get more .177 pellets and more Mags to make it more fun. 2 or 3 more should do it.

Things I liked: The weight and construction of this is "right"! At almost 8lbs, it feels and handles like the real deal. It is balanced and the trigger pull is better than average. It will take a couple mags to get a feel for the trigger. Can't wait for the PCP version.

Things I would have changed: The roto mag action is a little choppy ant times but a little lube or break in might fix that. I wish the ejector port had an actual spring loaded door.

What others should know: This rifle is an absolute blast to shoot. Out of the box with the red dot, it was 4" low, but windage was good. Shot 3" groups at 15m. I'm new to airguns, but this gun is very cool. Plus it saves on 9mm ammo. I bought several weight pellets and found that a medium weight does very well. HyperMax does well but has very little penetration. You better buy plenty of CO2 and extra mags.

  • Raymond from USA asked:

    will non-lead(alloy) pellets fly faster than lead pellets? And if so, about how much faster the velocity?

    • Mark from USA:

      Lead-free pellets will shoot faster. Perhaps 50-100 FPS. They do tend to be less accurate.

  • Raymond from USA asked:

    If I use the pellet seating tool, will it compromise the velocity of the pellets?

    • Mark from USA:


  • Raymond from USA asked:

    Exactly which parts of my Sig MPX do I need to oil?

    • Mark from USA:

      Put a couple of drops of Pellgun oil on the tips of the CO2 carts before they are pierced. The oil will be carried thru the gun.
