Sig Sauer MCX Gen 2 .177 Caliber Semi-Auto Pellet Air Rifle

This air rifle is a beast, not for its power or anything, but because it matches the real weapon’s weight and feels like a solid firearm. For a pellet gun that is .177, it’s a lot of fun to shoot and is pretty accurate out of the box with the attached sights. Great for plinking at targets. 90gr co2 cartridges aren’t cheap and though there is a PCP tank adapter and butt stock, it seems to get mixed reviews so I’ll keep using the co2. Would have been awesome if it came with two magazines, you will go through the 30 rounds before you know it because it’s so fun.

I was very pleasantly surprised when I received it at how good the make of this pellet rifle is. This thing is solid. If you didn’t know any better you’d think this thing was actually a real Rifle, but it’s not obviously. My hats are tipped to the design, designer and maker of this pellet rifle.

I'm a big sig fan boy, but this this has been a huge waste of money for me. I bought this to shoot rats getting into my chicken coop at night. At first I thought it was cool and accurate enough for my needs, even got a few rats, great. After a few mags and despite a fresh gas canister, the point of impact started to shift dramatically. I figure it's just breaking in, no biggy. It continues to drift a lot, and suddenly I get a hissing sound from the rifle after a couple shots. The hissing went away and I called it a fluke. Its just gotten worse, and at this point, if I plug a canister into this thing it just spits out the canister and wastes the whole thing. That wouldn't be a huge deal with a 12g canister, but it's wasting 10 dollars of gas for every time I try to get it to work. The parts are poorly manufactured. I regret spending the money I did on this pellet gun, the extra magazines and cannisters I needed to run it, and the time i spent trying to get it to work.

Works great. Gross great.

Got this MCX Gen 2 on 06/09/2023. Haven't had any problems with it at all. I've probably put at least 600 rounds through it so far. Also Purchased an extra magazine which came with 3 belts so now I have 4 belts that hold 30 rounds each. This thing is great for trying different optics and general target practice in the backyard. Good practice for when you go shoot your real guns.Also got an adapter so I can use 12 gram CO2 cartridges. https://www.amazon.com/dp/B08LDG1H7S?psc=1&ref=ppx_yo2ov_dt_b_product_details This also has worked out great. I'm getting about 60 shots per cartridge. I highly recommend this MCX. It's lots of fun!

My reason for buying this was to have the 30rd magazine capacity and that it is gas operated. I did not want a break barrel, or underlever pellet gun for varmint control because you have to break your sight picture, crank the weapon open, reload it, reacquire sight picture and hope you get another shot (if you missed). I also liked that I am familiar with the pattern of rifle and its ergonomics. let's start with the not-so-good things first. preface: I used only Sig branded 90 gram CO2 cartridges and Crosman Destroyer 7.4gr lead pellets in my initial set up and review. - The folding iron sights are airsoft grade junk, they don't lock into place, they have tons of play and don't really offer much for accuracy. That said I did manage 1" groups at about 25 feet. solidly "meh". I purchased a fixed 3X reflex optic that claims "4moa" accuracy and it made the close range grouping better, but did nothing to improve accuracy past 25 feet. - The muzzle velocity is hilariously bad for a CO2 .177 cal pellet rifle. sub 600FPS. ouch. Almost every lever gun or break barrel that you can buy at the store are rated around 1000fps. - Accuracy at distance, it doesn't have any. My yard is 100 feet from where I'm shooting to my target backstop, using state certified property survey markers as a reference. It shoots low and all over the place. - The stock is not adjustable. This is a design feature to accommodate the CO2 cartridge. - The barrel shroud is removable but it is also what holds the barrel, if you take it off the barrel just flops around loose. - The "MLOK" handguards are decent facsimile but really not up to par, and are held in with Phillips head screws. - It's kind of loud for a little pellet rifle. My .22lr with sub sonic ammo (no suppressor) is not much louder. than this. - The charging handle serves no purpose from what I can tell. It moves, it makes some kind of mechanical engagement noise, but doesn't cycle the magazine or reload. The trigger is DA every time, regardless of the charging handle. Okay. Now for some of the "good" qualities. - The magazine works really well, you can shoot it as quickly as you can and it wont misfeed or bind up. - You can use some actual AR accessories on this, foregrips, pistol grip, flashlight, optics, slings. - Really fun for plinking stuff up close, load a few magazines and go to town on cans and stuff. - You can upgrade this model with a PCP tank and regulator, that said it doesn't fix the poor velocity or accuracy. - It will shoot just about every type of .177 pellet on the market. I tried a whole bunch of different weight/brands of pellet in an attempt to make it lethal enough for varmints. - It feels like an AR, same weight, same size, same ergonomics. Ultimately this did not do what I wanted it to do. I wound up buying a Pre Charged Pneumatic mag fed bolt action .22 pellet gun for my varmint hunting. for the price, this is a heavy "Meh" don't buy. If you are only concerned with back yard plinking at relatively short distance and you absolutely need it to look "real" then I guess you'll do what I did and ignore the reviews and buy it anyway. If you plan to buy for varmint mitigation then I highly suggest expanding you price range another hundred dollars and getting something suited for the task, this wont kill a squirrel. TLDR: NOT adequate for accurate "long range" shots or varmint control. It is good for plinking and not much else.

Why did you pick this product vs others?: The prestige of the brand. This Sig sauer MCX is SWEET to fire. Great for plincking, but AWESOME for Pest control. Bye bye raccoons and possums. Build quality: Very well crafted/Developed Functionality: Fires on point very pristine Value for money: Would had paid even a bit more for this Sig Sauer MCX. Look: The slick black look gives it that Navy Seal distinguished appearance.

Love how realistic the whole thing is, from the way it looks to how much it weighs. Bought it for my son to practice carrying and shooting before putting a real rifle in his hands. I was very surprised by the accuracy and power it has, it's turned into a fun activity for us to do together!
