Wow what fun - Atrius Development Forced Reset Selector

I was concerned at first. I prefer to KISS and like the complete drop in FRT's. This went together fairly easy. Used with a RISE 140 trigger. Follow the instructions, Get a H2 buffer. I tried to use an H1 at first but would function consistently. Swapped to H2 and she never fails. It is so much fun to shoot. I used it in a carbine training class and never had an issue with it. I don't know how durable it makes it, but I didn't have any issues with the first 850 rounds. I may end up getting another after confirming durability after 10K rounds. I would definitely buy again.
