Description

SLR Premium BCG 5.56 - TiN Coated


Carrier Assembly: The enhanced bolt carrier is designed to reduce carrier tilt/cant during recoil and increasing reliability by strategically relocating key bearing surfaces.


Material: Case-hardened 8620 steel (complete care is taken during the heat treat process, so as to not harm the metal)


Finish: TiN


Gas Key: 4130 Steel, attached with Grade 8 hardware, torqued and properly staked into a milled “valley” around a fully encased ejection port area, for added strength and rigidity.


Cam Pin: Hardened 4340 cam pin.


Firing Pin: Mil Spec firing pin made of 8740 steel, center-less ground and Hard Chrome coated.


Bolt Assembly: The Bolt is “true” Mil Spec dimension and external surfaces are CNC ground after heat treat for a precision fit. These bolts are held to the highest possible tolerance possible. The “trumpet” area behind the gas rings, where carbon normally collects, is precision CNC Ground after heat treatment, to ensure as smooth of an area as possible, easing clean up, and longevity.

Extractor: 4340 Steel, Nitride Finish


Magnetic Particle Inspected (MPI) and High Pressure Tested (HPT)
