10 of 34 SIG Sauer MCX Scope Combo Reviews

Great, other than the trigger which feels gritty and somewhat heavy. My likelihood to recommend Sig as stated below is based on my other Sig firearms, rather than this one.
What can I say but the looks and feel of this Carbine air rifle is great ,its mostly all metal with authentic weight and mechanics .it will shoot good groups at 25 to 30 yards but anything past that is going to be luck if you hit your target .The rifled barrel could be better but for the price its doing its job.Mine is a newer model so they have fixed certain issues like making more c02 tanks fit .I use to see people say the JT 90 gram tanks don't work well they all do on mine.Super fun gun to shoot I wish hit really hit 700fps but in reality with 5.5 gr (some of the lightest I have )I can hit 620fps and higher sometimes but not very often average in the MCX is around 550fps which is what the MPX short barrel version says it does.Bottomline superfun for plinking.As for pest control on a new tank your can get some smaller birds and pigeons if they are close enough and with the right pellet.Yesterday I hit a black sparrow type bird with my 5th shot on a new tank and it actually killed it
Things I Would Have Changedmake it blow back or at least make the side dust cover open so you can clear jams .Also this should be field strippable because you need to clean it for longevity and accuracy.Up the FPS and foot pounds to at least 1000fps even if it makes it a little more expensive and maybe offer a full auto select as well.
What Others Should Knowwell after all this I need to mention that my first MCX broke after 3 and a half weeks I mean it just stopped firing out of knowhere .it was a brand new 90 gram tank (which are in short supply) wasted but since it was only 20 days they just swapped it out and gave me another one (I actually was gonna get a different airgun since they gave me credit back to spend on whatever I wanted but I got another one and so far so good and it shooting around 40fps faster .
ITS ACTAULLY A GREAT STARTER AIRGUN IF YOU HAVE THE CASH AND LIKE REPLICAS .ONE THING IT DID DO WAS MAKE ME WANT TO BUY A MORE POWERFUL AIR RIFLE .MAYBE THE SIG VIRTUS IN .22 BUT PROBABLY NOT IF YOU WANT A PEST CONTROL/HUNTING AIR RIFLE SPEND THE EXTRA 3OO DOLLARS AND GET A MID RANGE PCP LIKE THE HATSAN BULLPUB OR BENJAMIN AKELA IN ,22CAL OR.25 CAL

I’ve had the MCX a short period of time but have enjoyed shooting it. It’s simple to operate and functional. It took some time to bore sight and zero in the scope but it is accurate.

exactly what I was wanting. A rifle that has so far been a gas to shoot...

Excellent replica of the real SIG MCX rifle. Very good solid materials. Fit and function at this price is unbeatable. The performance is worth the money spent too.

The gun shot very accurate off target, but the scope won’t adjust to get the gun to zero

After the third pellet, nothing, except a little piece of something rattling around inside. YouTube has a video of a guy taking his apart and putting a tiny component back in its spot, putting the gun back together, and shooting it a few times until the piece falls out again. I could do the same thing, but the cartridge is still screwed in and I'm unwilling to risk my eyesight or something over this issue. After my 3 shots, the CO2 cartridge is nearly fully charged, so I'm not willing to risk losing my eyesight or something for this issue. I want to like and use this airgun (squirrels raiding bird feeders), but based on my experience, YouTube, and reading the comments on this site give me the impression that there may be one or two people in our midst that don't take pride in their work product, who knows, but it gets out the door only after the money comes in the door. "Made in Japan" is stamped on the side of the airgun, which is surprising, since every other Japanese product I have owned in the past decades has been superbly crafted and utterly reliable. It appears as if someone is coasting on those successes. Cudo's to Sig Sauer for allowing open and honest comments being posted on their web site. That shows that they are concerned and unafraid. My carry gun is a Sig P938, so I trust their workmanship with my life. I can't trust this airgun to startle a squirrel.

Worthless scope. Could not adjust it low enough to use it. I ended up putting an eotech he’s on it to make it usable. Still an inaccurate piece

Bought it over a month ago and have had great, inexpensive target shooting fun ever since
