The Closest Thing To A Maintenance Free BCG

I have owned a dozen different BCG's and this one is by far the lowest maintenance BCG I own. I have chrome, TiN, Parkerized, Cerro etc. This BCG has the best coatings in the right places to make it very dependable, and very low maintenance of ALL the bolts I have owned so far. Parkerized on the carrier and ejector which holds the lubrication and, chrome plated inside where the bolt rides to shed dirt and debris and keep the gas ring area holding a tight seal. The gas contact area is also chrome plated for a tight seal and no sticking due to fouling. It's the perfect combination of low maintenance and low wear! Get yours and never worry about your BCG EVER!!!!!!!!!!!

Great BCG !!!

Great BCG for the money. Gauged out very gas efficient (SOTAR Specs) with upgraded OCKS carrier key fasteners and Springco ejector and extractor springs. Combine that with chrome lined bolt run area and internal carrier key area (and a tested bolt) it should s a great bolt. Will buy more as needed
