The All-Rounder Carbine Bolt Carrier Group (ARC BCG) is our individually proof tested and mag particle inspected bolt with an inner diameter bolt run that is machined tighter than competitor offerings. This gives the bolt a “just right” gas seal inside of the carrier which increases gas efficiency and service life. Nearly all M16 BCG manufacturers do not compensate for the lack of chrome plating in a TDP bolt carrier, but we make up the difference with our tight tolerance machining.

Our bolt is shot-peened Crucible Carpenter 158®, and individually proof tested to guarantee service life. Our machined, chrome lined gas key is sealed against the carrier with Permatex gasket sealant and is affixed with our OCKS fasteners at 53 in/lbs w/thread locker. Our extractors are billet machined 4140 and manganese phosphate coated to retain grip against the casing rim, and utilize genuine Sprinco 5 coil extractor springs with rubber insert for added reliability and service life.

Specs:

  • 8620 M16 Carrier, tighter ID for DLC case depth
  • Shot-peened C158 bolt, individually proof tested
  • Diamond Like Carbon coated
  • Machined extractor installed with insert and Sprinco 5 coil spring
  • Serrated OCKS fasteners
  • Laser engraved with LS insignia so you can cyberbully an impoverished Redditor

These bolts come standard in our All-Rounder Carbine, and also come finished in Gold Titanium Nitride (TiN) available here!

    I normally run sonics but had a $100 gift certificate. I took this BCG down and detailed it. Very well made. Excellent stake with OCKS. as good or better as my usual from my exam.

    This is Quality Bcg. I run it in my 16 Radian model 1 suppressed, after 1000 rounds of suppressed fire the gas rings are still tight, the carbon wiped away with little to no resistance and the firing pin still looks immaculate. This will be a staple in future builds.
