It works, so far... - TacFire A2 AR-15/5.56 Fixed Stock Kit

Easy enough to install, have not fired it yet, however I have noticed that there is a lot of noise and movement of something in the butt when handling the rifle and when cycling the charging handle the bolt hangs up like the buffer tube that is included is not fitting right. It's also super long, the carbine buffer I had is half the size of the new one, I swapped it because the one included is TiN coated, but I may be switching back. The recoil spring is also very noisy, so until I live fire it I'm not sure fully if it's worth it or if it has some function flaws.
