Type: Pellet Rifle
Manufacturer: Sig Sauer ASP
Model: Sig Sauer MCX ASP
Materials: Metal and Nylon Fiber build.
Weight: 7.75 Pounds (3.5 kg).
Barrel: 17.7 inch steel rifled.
Propulsion: 88 or 90 Gram CO2.
Action: Semi auto with internal blowback. Single stage trigger single action trigger.
Ammunition Type: .177 caliber pellets.
Ammunition Capacity: 30 rounds belt fed.
FPS: Claimed up to 495 fps with 4.2 foot pounds of energy (5.7 Joules).

Trigger Pull: The trigger pull on the Sig Sauer MCX ASP .177 Caliber CO2 Pellet Rifle is actually pretty light and smooth when you consider the first part of the trigger pull is used to advance the belt fed 30 round magazine. You would think there would be more 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 bolt/striker which does lesson the overall amount of trigger pull required. The trigger pull is fairly short considering all that is going on and it's not overly heavy so quick and predictable action shooting is more than possible with the Sig Sauer MCX ASP .177 Caliber CO2 Pellet Rifle.

Accuracy: So far I have not done my official Field Test Shooting Video for the Sig Sauer MCX ASP .177 Caliber CO2 Pellet Rifle. That said I have performed shooting test with my Sig Sauer MPX and Sig Sauer MCX Virtus. Both of these Sig Sauer similar styled Air rifles where able to get nee tight groupings close to .5 inch groupings form 30 feet and 50 feet respectively. It will be interesting to see what the actual fps is using a standard lead .177 caliber pellet as the rating on the box is in Joules and not fps. I will assume a little under 500 fps.

Build Quality: The build quality for Sig Sauer MCX ASP .177 Caliber CO2 Pellet Rifle is very good, 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 Sigs belt fed magazine design works in terms of feeding and operation as all the Sig ASP Rifles use the same mechanical system and magazines. Sig also tests their APS Rifle line to withstand 15,000 rounds reliably.

Realism: The Sig Sauer MCX ASP .177 Caliber CO2 Pellet Rifle is a 1 to 1 replica of the real steel Sig Sauer MCX Rifle and looks absolutely the part other than the rear stock which has to accommodate the 90 gram CO2 tank. If you didn't know the rear stock was covering up the large 90 gram CO2 you probably wouldn’t have any idea and would probably think it was juts an aftermarket rear stock. Everything else about the Sig Sauer MCX ASP .177 Caliber CO2 Pellet Rifle is pretty much bang on in terms of realism including a fully working ambidextrous selector, magazine release and drop out magazine, charging handle and pop up sights.

Pros:

  • Few pellet firing multi shot semi-auto replica rifles on the market.
  • Near perfect replica of the real steel Sig Sauer MCX including licensing and trademarks.
  • Awesome build quality, lots of metal parts and the nylon parts are true to form and very solid.
  • Gun has been tested to shoot over 15000 rounds reliably.
  • 30 round full size belt fed magazine has super high capacity and works flawlessly.
  • Canada Legal version with max 5.7 Joule, should get decent fps.
  • 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 rail options for accessories, Picatinny and M-Lok.
  • Expecting it to be very accurate with it’s 17.7 inch rifled barrel form my experience with other Sig Sauer MCX and PMX Air Rifles.

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.
  • 88 and 90 gram CO2 can be a bit pricy but yields lots of shots per CO2.

Comments:

I really like the line of Sig Sauer Asp Pellet Rifles and it’s nice to know have one to offer to our Canadian Online Replica Airgun Shoppers! Some people have given the SIG ASP Air Rifle Line a bad rap but I think fo rte most part this is due to poor pellet choice. My findings with all of the Sig Sauer ASP Air Rifles is that once you find a pellet that works with it, you will have consistent pellet feeding and excellent accuracy. There are now a lot of CO2 BB Modern design Air Rifles out there but not many that shoot pellets in semi auto with a rifled barrel and high capacity magazine . Sig Sauer has done a great job bringing this missing product to the Airgun industry.

JUST BUY ONE

First off replica air guns is great...shipping was fast....out of the box gun not perfect...did a little tuning (cost nothing but time) and this thing is a tack driver out to 35 yards...now we'll over 1000 rounds ...one jam...my fault...30 shots is a blast...by the way I'm 50 plus with a extensive air gun collection...this has become my favorite....very picky...part of fun is tuning gun and fixing small flaws...if u thinking about mcx I say do it...well worth it ������

Power incredibly been detuned!!!

The gun looks and feels very solid, love the full metal construction frame and muzzle shround and even the peep sights! If the mag box is metal that would be prefect! The power have been incredibly detuned from rated 700fps (everyone knows that's a joke but US version can reach 650fps in real world) to a low 300ish... Can't believe my P17 SSP pistol shoots a lot faster than this heavy long rifle and I can see my pellet left the muzzle and fly to the target in my red dot sight picture... Not sure if that's related to the lowered speed, when using the open sight, the POI is about 4 inches lower than POA from just 6 yards away. That makes the fine factory peep sight a useless crap. After all, it groups ok for such a belt feeding semi auto CO2 gun. A great plinker at the bottom line.

lots of fun

Ran about 600 rds through this, so far just a few jams, nothing serious, good and powerful at 10 yards, sighted up wit a pinty scope,( not the best ) Totally satisfied with the power and accuracy, using Crossman Destroyer and a few different 7-10 gr pellets, found most to work pretty well, drills a hole in 1 and 1/2 inches of interlocking floor mat foam from 10 yards using Crossman pointed 7.9gr. Solid for about 150 shots, then starts to drop FPS. Looks good, feels good, fun to to fire.

The Sig Sauer MCX ASP .177 Caliber CO2 Pellet Rifle is my third go around with the Sig Sauer ASP Series of MCX and MPX Air Rifles. Back in 2016 I tested out the Sig Sauer MPX ASP .177 Caliber Pellet Rifle and it performed pretty well for me. Recently I reviewed the Sig Sauer MCX Virtus PCP .22 Caliber Pellet Rifle and again got good results once I figured out the right pellet for it. So here we are again with a very similar Sig Sauer Air Rifle....

The Sig Sauer MCX ASP .177 Caliber CO2 Pellet Rifle performed well for me in general, I did find that occasionally the belt did not index resulting in a misfire (no pellet fired) but the next pull of the trigger would index the belt resulting in a pellet firing, there where no jams and all rounds from the belt where fired. I am not sure why this happened as this did not happen to me with my other Sig Sauer Air Rifles. Perhaps I short triggered it a bit not getting a full belt index. I know many of you have been waiting for a Canadian version of the Sig Sauer MCX ASP .177 Caliber CO2 Pellet Rifle, now that we have them in the All Black Iron Sight Version and FDE Red Dot Version, make sure to get one as once we run out I am pretty sure we will no longer be able to get these Canada Import Legal Sig Sauer MCX ASP .177 Caliber CO2 Pellet Rifles.
