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.
