I’ve been so hesitant to install it because it looks like more work than I thought to take it apart. I know it says it improves consistency but could I expect a fps improvement too?
Any other upgrade parts coming out soon? An improved nylong grip would be nice. Also a nylon hand guard to match the stock bk1s length would be cool too.
