AR-15 BOLT CARRIER GROUP
FORWARD CONTROLS DESIGN AR-15 BOLT CARRIER GROUP DIMPLED BLACK
Mfr Part: SBCGDIMPLED 680665827121 The SBCG has a slight modification to the standard bolt carrier with regards to ergonomics for slick side uppers and uppers without a forward assist. The factory M16 carriers are very good, and improvements over them would be hard to come by. The S in SBCG stands for Secure Stacking, Slick Side. SBCG carrier has a series of serrations or dimples to aid in closing an out of battery bolt on upper receivers without a forward assist. The carrier still has forward assist pawl notches, and so is compatible with forward assist equipped uppers. The Secure Staking aspect involves SBCG's use of Ned Christiansen's OCKS (Optimized Carrier Key Screws), which when staked properly, offer significant improvement over conventional screws. OCKS have sharp, deep and effective knurling that extends to the top of the screw head. These splines form pockets for carrier key metal to flow into when the key is staked, resulting in gear tooth like engagement. Each SBCG has its firing pin protrusion checked, gas key torqued and staked, and is individually test fired (5rds of XM193) by our able partners at Sionics Weapons System. SBCG will ship as is, having been slightly lubed and dirtied by the test firing procedure. Serrated surface is machined in the concave area (forward of the gas vents of the carrier) to facilitate silent bolt closing on upper receivers without a forward assist. SBCG carriers have a subdued and small Cygnus laser engraved. NP3 coated mil-spec bolt carrier OCKS (optimized carrier key screws) Serrated forward assist surface on carrier SBCG bolts are manufactured from Carpenter 158® Steel. Each Bolt is HP/MPI tested and inspected. Each bolt is shot peened and comes with a Sprinco heavy extractor spring and black spring insert. The bolt and cam pin have been NP3 treated to enhance corrosion resistance and carbon build up. Shot Peened Sprinco 5-Coil Heavy Duty Extractor Spring Black Insert 100% HPT & MPI SBCG carriers are 8620 steel and machined to USGI specifications. The M16/M4 carrier includes a mil-spec gas key. The gas key is heat treated per TDP specifications and NP3 coated. The gas key is secured to the carrier via OCKS (Optimized Carrier Key Screws), torqued to spec values, and properly staked. Each carrier assembly is treated with a durable Nickel/PTFE plating which creates a permanently lubricious surface which reduces the need for lubrication."
