PMR 07, Lapco Big Shot Barrel, Dye UL Frame, CP ASA, ST locking Feed neck, Metal Back-cap, TechT L7 Bolt
No Kick back, very acurate
No extra O-Rings included or lube
Simply awesome, if you have a PMR you NEED this bolt. The difference is very noticable and well worth the cost. I noticed immediately No more Kick back and less noise. No issue's with installation, the on-line guide makes it so easy. TechT should have thrown in some extra O-rings and maybe a packet of Lube for the same cost. I researched a lot before I decided to buy this. I heard the previous bolt version was not the greatest, but they've fixed that now with this one L7. I had this delivered overnight.
