I had some FTF, but it was ammo related.



First let me state (Since many of you dont know me) that Im a Journeyman Toolmaker and found this to be simple enough to perform for most anyone given they follow the directions closely. Theres really no reason for aftermarket springs, we modify springs for dies all the time and they easily last 100,000 cycles without breakage. The Case hard on these may already be partially ground through by the finishing process, this may be why they tell you not to stone them.


I ran XM193(100rds), XM855(50rds), cheap ammo(several hundred rounds), high priced ammo(not many rounds) and only found problems with Brown Bear as some of the primers were seated too deep. Out of 40rds of BB I fired 3 didnt go off first time around, but these fired off when given a second chance.


Why a deep primer would cause this I have yet to figure out, but all three had this and the ones that went bang didnt so it had to be the problem.



All in all a good mod. I went from 8lbs down to 5lbs and with a seer engagement screw (up next) this trigger would be very sweet.
