Its nice to see the small AR parts are getting attention. The quality of the run of the mill mil spec parts has drastically gone downhill. I recently discovered a forward assist that was out of spec. that had been causing ejection issues by slowing down the BCG, IE: it was to long. Definitely was not on the list of cures for weak ejection. Also has a safety selector detent on my sons rifle break and render the safety useless while running some drills.
