I enjoy the rifle and think its accuracy is superb. However, the rear site has far too much play in it. Compared to the match grade site on my AR15 the MAR 177 site just doesn't cut it. However, the oportunity to train at a fraction of the cost makes this upper well worth the invstment!

This kit has removed the last of my excuses not to practice - time used up to get to the range. Now I can get in an hour of offhand practice while my wife prepares dinner. Thank you Crosman! I use the hand pump, which lasts me about 5 practice sessions and provides much needed exercise.

Well I have put a few thousand rounds through this rifle. Accuracy and function have been nearly flawless. My only reason for not giving 5 stars is the rear sight. I expected much better for a rifle at this price. Sight had significant play in it . I would be clicking up and down and side to side between shooting sessions to get back on call. Ended up buying a RR match sight, taking a hacksaw to it to cut out a slot for the magazine and now now poi change.

Except for the sight a great product.

nice training rifle, but I wish the rear sight was interchangeable with standard sight parts. It would be easier to upgrade the sight and windage screw. I know it won't get moved much, but I shoot with a lens in the rear sight and changed the rear leaf but would have changed the windage screw also.

Kit arrived today with hand pump and 2 extra 10 shot rotary pellet mags. Able to fit on STAG AR lower, only slight persuasion necessary on rear cross pin. Pump was easy to use, takes a bit of work so do it ahead or bring a minion to pump for you if you don't want your heart rate up there. The feel of the conversion, the ability to use the same trigger, the fake mag all make it just like the 5.56 mm without the noise, recoil and ammunition expense, much less not leaving the house. I have seen reviews that said that it didn't cock reliably, you have to be sure to pull ALL the way to the rear and then push it in place so the cocking lever locks. The rotary mags are easy enough to fill with pellets and then load into the gun. When they are empty the cocking lever does not go forward so you know youv'e finished. In short I put 90 pellets down range in the basement, and nearly zeroed in just shooting off hand. Is it cheap? $600+ when you add pump or scuba yoke, extra mags? One of my good gun stores had 1000 rounds of 5.56 mm for $300+. Do that 3 times and you've paid for it. Not for everyone, but it is sweet ...

I am just getting into Highpower Rifle competition and saw the MAR177 so I bought one to train with. Well it has worked as I saw my scores improve steadily and in my very first Service Rifle event I shot Expert scores. My offhand needed work (whos doesn't) and using the MAR177 and studying the Ways of The Rifle I got my position right, and now I'm in the low to mid 90's on offhand. I get up in the morning and shoot 20-40 rounds and do the same when I get home from work and again in the evening. Being able to train with my Service Rifle lower is just fantastic!

Please develop a semi-auto version then we could train exactly like a real XTC event!! I do train at getting into position and getting the first shot off within 8-10 seconds.

Thank you!

My wife has taken an interest in rifle shooting now. She is right handed but must shoot left handed due to vision problem. She never wanted to do this "in public" because she thought she would be awful at it, but now at home she is building her confidence and skill.

If you offered these in a sub 12 foot pound version, ie making 11-11.5 foot pound energy you would shift a lot with hunters in the UK, hell even hunters in the USA (where legal) would love a full powered version of this rifle!
