hey all, ive got a pof ar with a timney trigger, got it used, the problem is that it double taps every time i fire it. there are small allen head screws inside the assembly which looks like adjustment scews. im sure the sear/hammer engagement is minimal and causing this problem but does anyone know if its adjustable and how ? im savvy with 1911 triggers but not so with ars yet. thanks for any help.
