LR308 Dual Ejector Black Nitride - QPQ Bolt
Why pay more, when you can have a high quality replacement bolt for an un-paralleled price? If you have been working on building an LR308 and have been waiting for a quality, yet well priced bolt for your other BCG, we have what you need.
The bolt has dual ejectors (standard BCG's have one ejector). Additionally, under the extractor we have installed outer and inner springs and two crane O-rings. All of these features provide for more reliable, superior and unprecedented extraction.
DUAL EJECTOR: "Two is one, one is none", a motto to live by. With this BCG we added a second ejector in the bolt. Building this redundancy allows our BCG to eject and extract efficiently and consistently. This is truly a remarkable and uncommon feature offered in bolt carrier groups.
No MIM parts are used in this bolt.
Bolt: Case hardened 9310 steel, all bolt parts are case hardened and shot peened with two ejectors and two crane O-rings and dual extractor springs installed.
QPQ: This is an extreme case hardening process which turns the steel black and hardens the surface of the steel and extends the life of the product. QPQ stands for Quench Polish Quench.
