Sig Sauer, a leader in centerfire pistol and modern sporting rifles made entry into the airgun market debuting a new airgun line at the 2015 Shot Show in Las Vegas. Their goal was to develop an airgun training rifle for realistic economical tactical drills. Here we look at the Sig Sauer MCX ASP, an airgun replica of the popular Sig Sauer MCX.

The Sig Sauer MCX ASP comes in an attractive package embeded in molded to fit styrofoam. When removing the airgun you can’t help but notice this MCX ASP does have the look and feel of the original powder burning MCX. A true metal upper and lower housing (one peice), metal ambidextrous flip on/off safety and a metal push button magazine release. Sig Sauger even added several non-functioning parts to further give the airgun the look and feel of the centerfire MCX such as a charging handle, forward assist and ejection port dust cover.

The Sig Sauer MCX ASP weighs 8 LBS 1 OZ, measures 34 1/2″ long with a 13″ trigger pull and is powered by means of a 88 gram CO2 cartridge (sold separately) and is easy to install and replace when empty. Simply push the release button on the rear stock and slide it rearward to expose the CO2 cartridge.

Just like the Centerfire version, the Sig Sauer is a semi automatic and with each pull of the trigger one pellet is fired with out the need to cock the rifle. In addition, just like the powder burning version, the MCX ASP holds 30 rounds of ammo compliments of a unique belt fed magazine that is easy to load, but be sure to read the instruction first as you want to be careful in how the belt is removed and reinserted.

Next we loaded up the 30 round magazine with JSB Exact 8.4 grain, installed a new 88 gram CO2 cartridge and went outside with the Chronograph. Results varied by quite a margin but remembering this airgun was built for economical tactical training rather than hunting or precision shooting, we were not that surprised.  We’ suspect a fair amount of CO2 pressure is being lost do to the blow-back feature on the airgun to give it more of the feel of it’s powder burning sibling, which is of coarse is what it was designed to do.  Below are our results waiting a few seconds in between to fire the next round.

We brought the Sig Sauer MCX ASP back inside, mounted an Optisan EVX 4-16×44, reloaded the 30 round belt magazine and went back outside for a little accuracy testing. We placed a target at 15 yards and used the first 10 shots to get close to the bulleye and then shot two 10 round groups.

Where this airgun shines is in appearance and feel and that was what it’s main funtion is, an economical tactical training tool (currently less that $200 as of this writting). It’s not a hunting rifle nor is it built for accuracy but for the average airgunner looking to knock down cans or have a little speed shoot competition with your freinds, this Sig Sauer MCX ASP is fun to shoot. Being a semi-automatic, there no need to cock a heavy spring between shots, cycle a bolt or own the equipment required for a PCP, just a load a fresh CO2 cartidge on occasion, load the 30 round belt and let the cans fall.
