Worth the wait! Definitely! The machine devours CCI Quiet SA with zero modifications. Accurate, my first outing was at a 50 foot range, put 44/50 in the black on a B3 target. 4 flyers were the result of sloppy shooting... This product is the combination of precision machining and awesome customer service.

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!
