Nice rifle! I have a couple , a service grade and a field grade , both from the CMP. with my crappy old eyes the service will do about a clip into 2.5-3" at 100 yds, and the field into about 3-4". But they did not come that way the field grade in particular was all over an 12" square when I received it, it took staking the gas tube and some stock wood removal inside the barrel channel and operating rod cut to make it shoot. Quite frankly, I was going to have a new tube put on it, but decided to tinker and was pleasantly surprised at how the gun tightened up. The same sort of thing was done to the service grade, and the stock had to be shimmed for a tight fit- that gun went from shooting vertical strings 3" wide by 5" high to shooting nice round groups at 2.5"-3". The CMP just can't be beat for price/quality, and the customer service is #1.
