416R Stainless Steel Barrel

The 416R stainless steel barrel provides corrosion resistance and a bright finish that stands out visually. Government profile maintains consistent weight distribution through the barrel length. The 1:7 twist stabilizes heavier projectiles effectively at close to moderate range. Stainless steel construction offers durability in varied environmental conditions.

SBR Ready Design Intent

This kit ships without a brace. It is intended for customers who prefer to select their own final setup based on their specific application and compliance requirements. Configuration based, this approach provides flexibility for individual builds.

Compact Platform Configuration

The 7.5 inch barrel with pistol length gas system creates a short, maneuverable setup. Micro low profile gas block keeps the sight plane clean under the handguard. The pistol gas system provides reliable cycling with standard 5.56 NATO ammunition.

Premium Bolt Carrier Group

The bolt carrier group features a 9310 alloy steel bolt head paired with an 8620 alloy steel body. Nitride finish provides wear resistance and corrosion protection across the entire carrier group. This material combination balances strength and durability in a high pressure platform.

Full Build Kit Components

This kit includes the upper assembly with barrel and handguard, bolt carrier group, charging handle, buffer tube, buffer, recoil spring, castle nut, end plate, and lower parts kit. Lower receiver not included.
