After a ton of reading here, and some most helpful advice from John D. (many thanks Mr. JD) It seems that Century products is a crapshoot. Correct me or flame me if you need to. I have found 0 problems with the AR15 type I now have from them. I even stooped to feed it 40 rounds of steel case Wolf ammo. Nasty stuff. I have no feed problems, nothing. Maybe I got a good one. It will stay under 2 MOA a one hundred consistently if my old eyes do their part. My one question for any of you is there a step by step on here to changing it over to a A3 reciever to aid my eye sight with optics. I have also looked at the scope on Sarco that mounts to the carry handle. Any and all opinions appreciated. Thanks in advance.
