Things I liked:

A very good replica gun. Not a bad trigger, similar to the one on the Sig Sauer P226 pellet pistol. Loading is easy if instructions are read carefully. At 12 meters most of my shots group inside a 2" circle; the rest inside a 3" circle, with a few beyond that. Not as accurate as an R7 or Prosport but fine for plinking. With the 90 gram bottle I get 240 shots/8 belts of 30 pellets. Tried JSB RS, Exact and Exact Express. Will use the Exact Expresses in the future although all three were good. Choreographed the last bottle with the Exact Expresses @65 degree temp. Spaced shots about 10 seconds apart. Came up with 7 averages @32 shots each--502 to 402 fps. SD's from 82 to 24. So although there's a wide spread and a shift in the averages as you go through a bottle, the shot groupings remain rather consistent, with the POI dropping with the last two reloads. Perhaps the numbers would rise if I shot every 30 seconds but that wouldn't be much fun. I do like this rifle a lot, esp for $200

Things I would have changed:

The scope isn't too bad, especially at this price point. However, I like scopes with an adjustable objective for crisp focusing, @ 12 meters in this case, so I put a Hawke 2-7x32 AO scope on the mounts that came with the rifle. I'm very pleased with that arrangement. Also I would like extra belts for the magazine to be come available ASAP

What others should know:

I'm not getting anything close to the advertised 750 fps. I thought I'd get about 575-600 fps with normal weight lead pellets but I chronied with two different bottles on two different days with similar results. I'll be shooting this in my basement throughout the cold months so it doesn't matter much now. I'm not sure how much the fps will go up in 70-90 degree days we get around here in the summer. But I've got other fine rifles for longer distances when outside. My grandsons are going to love shooting this rifle when they visit next summer.

Low quality materials

This is my second MCX. The first one leaked air after my 4th co2. The 5th leaked and wasted the whole cylinder. Sig was nice to replace the gun. Second one arrived after a few weeks. This time, I made sure I empty the co2 and store it without the co2 on it. Few months later i took it out for some plinking. As soon as I put a fresh co2, same thing happened. I have not called Sig this time. I serviced it myself and what I found was a part where the co2 passes through got bent because of the pressure. I'm looking for a spare part but its not available. If only they used metal rather than aluminum part where high air pressure is concerned, there wouldn't be any issues. I'm sure they have figured this out by now but for me, its out of the 1-year warranty so I just have to swallow it. They should have just stuck to making firearms and left this to airgun companies. Sorry Sig.

    Mcx air rifle and scope

    Rifle is heavy too heavy on front end. Scope is not good enough for hunting birds. Need tracer pellets invented , to allow sight of rounds when fired.

    Caution—say no to the scope

    The pellet gun itself is okay but the scope is terrible. It will not sight in. Yes, I’ve sighted my share of rifles and this scope will not move. I just put a old scope of mine on it and now it is pretty good. I still had to max out the upper elevation.

    Not SIG quality

    Sorry to say I am very disappointed. Magazine jammed and not able to extract. Disappointed with fps. Overall quality not what I expected from a SIG product.

    Lousy Scope

    The Elevation Adjustment on the Scope was broken and the scope was highly underpowered. I had to purchase a better scope.
