I own the MPX without the fancy red dot sight.I've had tons of fun with it without any of the jamming problems. Simply seat your pellets correctly with the provided tool.
Pros3o shot magazine belt and 88 or 90 gram CO2 bottle means you can shoot as quickly as you can pull the trigger!
ConsYou will need to buy extra magazines that come with extra belts for intense firefights.
Best Uses Not meant for long range hunting. It's better for back yard practice and drilling -- weighs, it's size, and feels almost like the non-airgun Sig Sauer version.

Gr8 design using a 9gram cylinder in place of ARÔ€™s buffer tube for gas powered pellet rifle! Wish they made the magazine the same size as a real ARÔ€™s magazine!

Set up and instructions are real simple. Loading the magazine takes time, maybe manufacturer should supply two on purchase. Having fun every time, plinking has never been this good.

Absolute Blast of an Airgun!
July 30, 2017
Having previously purchased one of Sig's official P226 CO2 pistols and thoroughly enjoyed it I decided to try one of their CO2 replica rifles. Sig offers two versions of their famed full-auto MPX SBR. One is the MCX which emulates the MPX with a large 'can' or suppressor threaded on the front. The suppressor is not functional, it is a barrel shroud that threads on over the rifled steel barrel to give that touch of cool folks crave. The MPX CO2 replica looks like it's namesake. It has the short handguard and realistic 'flash hider' protruding just the right amount past the handguard. It is the one I settled on after much indecision over which one I should try first. As it turns out, either one would have been great! I decided on the FDE version of the MPX with the optional red dot sight that augments the flip up 'iron' sights on the base model.

I decided to order an extra magazine (comes with three belts), and a couple of 90 gram CO2 cylinders so I could immediately test my new purchase when it arrived. I already had several tins of .177 pellets, the caliber the MPX uses, and other basics like the correct type of oil to use when installing the CO2 cylinder and properly lubing the airgun. All items arrived ahead of schedule, just in time for a weekend at my place in Central Oregon.

As I unboxed the MPX I have to say I was very impressed with the attention to detail and the overall quality and heft of the rifle. The iron sights come installed though you can move them around a little if you like. They manually flip up-they don't have springs that make them pop up by hitting a button. They hold their position well but do not lock into place. The front and rear sights are fully adjustable and zeroed easily at 10 yards. The front sight is of the AR style and uses a similar adjustment tool to run the sight stalk up and down to change elevation (the included pellet seating tool doubles as a sight adjustment tool).

The red dot sight that comes with the MPX is an "R20" sight. It is meant to emulate the Romeo sight Sig markets. I have seen other reviews where folks said the included battery was dead. My guess is they fell victim to the same error I made. The battery was actually tightly wrapped in cellophane. If you don't look close and just put it in, the contacts are of course insulated and yes, the sight will not light up. I unwrapped the battery and the red dot came to life! The red dot has two light levels upon turning it on. One is the base brightness level that might be too bright from some. Punch the on button again and a dimmer version is displayed. You can then use the plus or minus buttons to increase or decrease brightness of the dot. It worked well. The sight zeroed easily and after banging on it a few times to test it, I found it still held zero. I am sure it isn't waterproof or really shock proof but it worked well during my first 240 rounds with no issues.

Back to the rifle! This unit is a quantum leap above the Sig blowback CO2 pistol I previously tried. The ambi-safety is smooth and it works. The charging handle is actually required to cock the weapon the first time after installing the CO2 and the magazine. Nice touch of realism! The trigger is far better than I expected. The first 'stage' of take-up the trigger is actually advancing the pellet belt inside the magazine. You then come up against a wall and if you continue to squeeze smoothly the trigger releases and fires the shot. Impressive I thought. And accurate! I tested the MPX all the way out to 25 yards. At 10 and 20 yards I used the open sights and no problems nailing tin cans of various sizes, sniping pine cones off of the trees in the backyard. At 25 yards with the red dot and bracing against a tree I was able to keep most of my shots within and inch and a half. There were some flyers but I chalk that up to myself and the wind blowing the target. I am really impressed with the accuracy. This thing is going to be a hoot shooting reactive targets!

One area that others have mentioned is the lightweight plastic magazines that actually house the pellet belts. Yes, it would add an extra measure of realism if they were metal instead of plastic. But you have to get into the spirit a bit and realize that metal mags will be harder to produce, cost more and add only a little extra value to an already great experience. I won't get into the mechanics of how you load the pellets in the belts or install the belts in the magazine. If you read the instruction sheet that comes with the rifle and follow those instructions it will work first time-every time. They do supply a seating tool that as I mentioned before doubles as a sight adjusting tool. Proper seating of the pellets is essential and the tool works well for that purpose. I didn't encounter any issues with inserting the magazine into the MPX or any problems with feeding. I actually used Crossman 7.4 grain pellets for all my initial testing. These are heavier than generally recommended but they worked well and are inexpensive. It is important to center a pellet in the "port" of the magazine so that it centers on the bore of the rifle. It will make it easier for the trigger mechanism to lock up on the belt the first time and accurately advance from shot to shot.

To sum it all up, this is one amazing and fun CO2 air gun. It will easily do 240 shots on one 90 gram CO2 cartridge and if you do your part, out to 25 yards it will hit where you put the dot. The stock feels plenty solid and the overall feel of the rifle is one of quality and solidness. It will not disappoint!

ProsRealistic feel and heft. Good build quality. Reliable Easy to load. Decent Red Dot Good functional iron sights
ConsFinish appears a bit thin on some parts. Likely to see some bright metal start to show through after extended handling. Magazine is light weight plastic. Loading door feels fragile so be careful with it or you could break it if you bend too far backwards. It makes you want to go out and drop big money on the real thing!
