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.
