For that small minority who may not have read last month’s review of SIG’s P226 airgun, not only did SIG launch an airgun line, they went the extra mile and developed a good selection of extremely accurate pellets and a large choice of airgun targets. This was extremely smart on their part, as this new line will be a huge drawing card for kids … and grown-up kids, of course.
It is the same weight as the original model, and is designed to deliver comparable handling. This “real gun” feel guarantees that it will be fun and challenging to shoot, but as with the P226, it’s also great for training purposes. The MCX is charged by CO2, which is a new experience for me. Even as a kid I have never had an airgun that used a CO2 canister. My airguns have always been pump-ups, break-action or PCPs.
The MCX is quite simple to operate. To begin with, it uses a 90-gram canister instead of the normal 12-gram ones. To install a canister you remove the butt stock, screw it in and replace the stock over it. I’m sure it was designed around a larger canister because it holds a 30 shot clip. And speaking of clips, the clip pops out the same as on your regular AR. Inside is a rotary belt that you insert pellets into, which will hold 30 pellets. To load it you pull back the bolt just like on your AR. The gun does have a forward assist bolt, but it is merely decorative, not functional.
With it holding 30 pellets and being a semiauto, that makes it a fun gun to shoot. I fell in love with it right when I opened the box, and was impressed with how solid it felt.
For the initial voyage, we went out to shoot and chronograph. There were a few ground squirrels out, but we tried to focus on the task at hand. We had a lot of guns to shoot that day and pellets to test. But we ﬁnally broke down and shot ground squirrels for a couple of hours when we were ﬁnished with the real work.
Although the gun is listed as shooting up to 750 feet per second, we attained only 590. But fps can vary greatly for a variety of reasons, such as if you have a fully charged canister or not, what kind of pellet that you’re shooting and variations in temperature. I think it’d be fun to chronograph it in 30-degree weather and then again in 105-degree conditions, conducting both tests on a new canister and the same pellets, and compare speeds.
I was unhappy with the groups that I was getting on the range. But I took it along when we went to the mountains for some coyote hunting, and I was able to retest in the middle of the day when things slowed down. I got a little over a 7/8-inch three-shot group at 30 feet. That’s more like it.
I wrote about hunting ground squirrels elsewhere in this issue, and mentioned that on a good day I’ll get 400 to 500 shots oﬀ, so the cost of .22 ammo can quickly add up. So for close shots in a similar hunting scenario, the MCX will not only be a fun little gun to shoot, but it’s also very economical.
The MCX comes with a 1-4×24 SIG Sauer scope, and I was impressed by how crisp and clear it is. The crosshairs have marks for distance and windage. The only downside is that the scope is a 1-4x; as I’m shooting small targets and pushing the limit on yardage when I’m hunting with my airguns, I wish that it was at least a 3-9x.
The trigger was really rough at ﬁrst. But while I was trying to measure the poundage, it leveled out and pulled straight through at 6.25 pounds. Maybe it just had to break in to get smooth. Obviously, if it had a better trigger, I know that I could tighten my group.
But despite the minor issues with the trigger and scope, it is a great little gun, and as soon as the ground squirrels come out in full force I’m going to burn the barrel out. Shooters of all ages will certainly enjoy it, but as with most modern airguns, it is deﬁnitely not a toy. ASJ
