Trigger Pull: The trigger pull on the Sig Sauer MPX ASP .177 Caliber Pellet Rifle is actually pretty decent when you consider the first part of the trigger pull is used to advance the belt fed 30 round magazine. One would think that there would be a lot of added friction from the belt but this does not seem to be the case. There is some internal blowback action going on but it is only used to cock the internal hammer/striker which does lesson the overall amount of trigger pull required. The trigger pull is shorter than expected with all that is going on and it's not overly heavy so quick and predictable action shooting is very possible with the Sig Sauer MPX ASP .177 Caliber Pellet Rifle.

Accuracy: So far I have not done my official Field Test Shooting Video for the  MPX ASP .177 Caliber Pellet Rifle but I did have the chance to get out and shoot some rounds down range at my Sig provided Quad Shooting Gallery that I had setup about 35-40 feet away. Even though I did not have my red dot all perfectly sighted in I was still able to hit the smallish metal targets fairly well using the Sig Sauer MPX ASP. In terms of velocity you can expect from the Sig Sauer MPX ASP .177 Caliber Pellet Rifle, 600 fps is a bit optimistic. Sig did send me a real world fps performance spread sheet they had conducted using both 5.25 grain alloy pellets and 8.18 grain lead pellets shooting 8 rounds and averaging out the fps. The 5.25 grain pellets averaged in at just over 500 fps while the heavier 8.18 grain pellets came in with an average of just under 450 fps. Pretty much what I would expect from a shorter barreled CO2 rifle.

Build Quality: The build quality for Sig Sauer MPX ASP .177 Caliber Pellet Rifle is excellent, you can tell Sig Sauer had a lot of hands on in the design and production of this Pellet Shooting Air Rifle! The materials used and fit and finish are top notch and the mechanical function again is really good, I am kind of amazed at how well their belt fed rotary magazine design works in terms of feeding and operation. So far I have not experienced any pellet feeding problems at all using both lead and alloy flathead pellets.

Realism: The Sig Sauer MPX ASP .177 Caliber Pellet Rifle is for the most part designed to be used as a side by side optional training aid for the real steel Sig Sauer MPX Rifle. Sig wanted the pellet version to look and feel as close as posable and Sig has done a good job with this. Other than the lessor recoil and noise factor, the Sig Sauer MPX ASP .177 Caliber Pellet Rifle works and shoots much the same as a real steel Sig Sauer MPX Rifle.

Pros:

  • Has to be the best semi auto pellet rifle replica I have seen and shot to date.
  • Near perfect replica of the real steel Sig Sauer MPX including licensing and trademarks.
  • Awesome build quality, lots of metal parts and the nylon parts are true to form and very solid.
  • Rifle has been tested to shoot over 15,000 rounds reliably.
  • 30 round full size belt fed magazine has super high capacity and works flawlessly.
  • Decent fps performance, about what I would expect from a multi-shot CO2pellet shooter and totally usable.
  • Trigger feels really good, not too long or to heavy and very consistent feel on every shot.
  • Fully adjustable pop up front and rear sights.
  • Lots of rails for your pick of sight options and other add on accessories.
  • Very accurate with it’s 8 inch rifled barrel.

Cons:

  • Rear stock is none adjustable so the gun may feel kind of cramped for larger shooters.
  • Internal blowback action does not advance the belt fed magazine but does cock the internal hammer.
  • FPS claim of 600 fps seems a bit optimistic compared to real world testing.

Comments:

I have been waiting to get my hands on the Sig Sauer MPX ASP .177 Caliber Pellet Rifle for some time now and the wait has been worth it for sure. There are really no other guns out there right now other than perhaps the Umarex CX4 Storm that compare to the Sig Sauer MPX ASP .177 Caliber Pellet Rifle and even so I feel the Sig Sauer MPX is by far the better of the two CO2 Air Rifles. OK so the MPX does not really come close to hitting 600 fps but did you really believe that in the first place? Still consistent 450 fps from a decent grain lead pellet is about what you would expect from a short barreled CO2 rifle. If you do want more fps then look at the MCX with over double the barrel length of the MPX, this will easily get you an additional 100+fps for those of you who thrive on velocity performance. I am fine with 450-500 fps since this is all that is needed to accuracy shoot and nock over most targets at a variety of ranges.
