The Heart Of The AR-15 Part 2: The Grit Cutter BCG

Product Highlight

$350?

What makes the Grit Cutter worth $350?

Respectfully, Lead & Steel offers the best possible BCG for the All-Rounder Carbine; the Grit Cutter.

Sand Cuts; channels to prevent debris from interfering with the carrier & upper receiver such as dirt, sand, mud or even carbon build-up.

Extended Carrier Cuts; elongated carrier rails increase carrier stability inside the upper receiver for more consistent bolt reciprocation.

Belly Scallops; Carrier belly relief cuts that allow smoother loaded magazine insertion on a closed bolt. 

Two-Step Finish; Our proprietary two-step Titanium Nitride (TiN) PVD coating process provides superior durability. To ensure comprehensive coverage with TiN PVD’s line-of-sight limitations, each carrier is gas nitrided first, to diffuse a wear-proof base layer into the interior surfaces. Then, each carrier’s exterior surfaces are bead blasted before TiN PVD coating. This dual-layer process ensures every corner of each carrier is totally protected. 

Each BCG is both individually proof- & mag-particle inspected, with an inner-diameter run machined as tight as possible. Extremely tight tolerances afford a superior gas seal inside the carrier, which can exponentially increase gas efficiency & service life.

Each bolt is shot-peened Crucible Carpenter 158® & individually proof-tested.

Each machined, chrome-lined gas key is sealed to each carrier with Permatex gasket sealant & affixed with our serrated OCKS fasteners, staked at 53 in/lbs with thread locker to ensure reliability & extend service life. 

Each extractor is billet machined 4140 & manganese phosphate coated to retain grip against the casing rim, & utilizes genuine Sprinco 5 coil extractor springs with rubber insert for added reliability & service life. 

The Grit Cutter comes standard with the All-Rounder Carbine & is also available in DLC.
