Description

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.

This is my second Sig Air Rifle, the other is a MCX. Both air guns are very accurate with and without a red dot. I was able immediately attached a UTG bipod by repositioning one rail from the side to the bottom. I am able to consistently hit a target at 25 yds. My only concern is the lack of parts for this weapon from Sig (I couldn’t replace a damaged stock ring even if I bought a new stock.

The mini red dot does not function properly (on/off feature does not work thereby draining battery). Already sent in to Sig Sauer for tech to repair. Tech could not find anything wrong. Mini red dot still does not turn off and battery needs to replaced daily. Accuracy is very poor.

I haven’t fired it yet but when I went to the website to register it for warranty. The website said it was an old item or previous owned. I got just a little heated. So I sit it aside to call in to research it more

I've seen many reviews on various sites that claim major problems with the MPX but 750 pellets in I have yet to experience anything even close to a jam. I've also seen complaints of a heavy trigger pull but I have found the pull to be lighter than on many of my powder burning guns and certainly more than serviceable for the MPX's applications as a plinker and training device. Overall the gun seems well built and features a lot more metal than say, the DPMS SBR from Crosman. It's also quite accurate for the type of gun it is.

Since the gun already has internal blowback, I'd love to see the ejection port/dust cover be "functional" and for there to be lock back after the last round.

There are converters available to allow the MPX to take a single 12-gram CO2 powerlet and I highly recommend you pick one up. You'll get 35-45 good shots, perfect for a quick session when you don't want to waste an 88-gram powerlet.

I bought this air gun mainly to chase pests away from my home. Initially I couldn’t hit anything consistently. The red dot sight mine came with was terribly inaccurate, as were the iron sights. I put a Romeo 5 red dot on my MPX, which greatly improved the accuracy. For what I paid, I can’t complain. With the Romeo 5 accuracy was satisfactory for my purposes. My son, grandson and I always have fun when we get together target shooting. It is a great way to teach and learn responsible gun handling skills without the loud noise and expensive ammunition.

I purchased this rife w/ little expectation (based on the price), but have been thrilled with the quality and performance. Great gun for training, plinking or young shooters. Well packaged and delivered!

Because of look and weight it feels like you are using a valid weapon to practice with.
