I have had my mini-14 for many years. I don't think there is a more reliable auto loader made. The accuracy was so-so,,, then I read on one for the Mini-14 boards about this double muzzel break ???. They have them at cheaperthandirt.com for $19.95 ?? I put it on and couldn't believe the difference ! I put it on and off 4 times in one day. It cut the group size in half (or More). I don't think it has to do with being a break. I think the weight change on the end of the barrel tuned it some??? who know but it worked. This new Mini-14 is a bull barrel with the harmonic tuner. It is a dream come true. I didn't include the tuning proceedure I used in the movie . That was only a test to see if it made a difference. 150 rounds later and it was ready !
I want one
