Brownells USA Absolutely outstanding 24/10/2015

This is one terrific piece of hardware. I had ejection issues that I could not diagnose and decided to upgrade my LR308 to a new bolt, and I chose this unit. After some research I decided on the JP bolt, and am very impressed. The finish on the Bolt is so smooth that it feels like it is lubed up, as I to check to see if there oil on my hands. The BCG ejects so smooth and efficient that I ordered a JP adjustable gas block to fine tune the gun, and although this is an expensive item, it is the heart of the gun. This is the only other part of my gun on par with my Geissle trigger. A great buy

Brownells USA JP LMOS BCG 25/03/2014

This BCG is unbelievable. Machining is perfect and fitment was outstanding. By far the nicest and most expensive BCG i ever used. Wanted to try this on my latest build to see if was worth it. If you plan on shooting competition or heavy use, get this bolt. It won't let you down. Running this with the JP captured spring buffer and couldn't be happier with the results.
