Top quality, after Larry walked me through a magazine fix it runs like a top. Very accurate.

I shoot open-sight standing silhouette with my Nelson adapter. It added 2 points to my score compared to my M41!

I had a Matchdot II installed on it and after sighting it was awesome, but the actual upper worked flawlessly and the fit and finish was superb. The Upper and Larry are the Best!
