The Buck Wylde is a complete rifle build kit designed for shooters who want a versatile, reliable platform without the complexity of sourcing individual components. This kit pairs a 4150 CrMoV barrel with a 7075 T6 aluminum upper receiver and includes everything you need except the lower receiver. The .223 Wylde chamber handles both .223 Remington and 5.56 NATO ammunition, making it flexible for different shooting applications and ammunition availability.
The 16-inch 4150 CrMoV barrel delivers the balance most shooters want. The 1:8 twist rate stabilizes a wide range of projectile weights, and the HBAR profile manages heat during extended shooting sessions. Phosphate finish provides corrosion resistance in field conditions. The .223 Wylde chamber accepts both .223 Remington and 5.56 NATO, eliminating ammunition compatibility concerns.
The 7075 T6 aluminum upper receiver is machined for tight tolerances and anodized for protection. The integrated micro low-profile gas block matches the 0.750 O.D. barrel and keeps the rail profile clean. M-Lok slots on the handguard support modern optics and accessory mounting without rail clutter. The nitride bolt carrier group is built from premium alloy steel and designed for reliable cycling across ammunition variants.
This kit includes the upper assembly, bolt carrier group, charging handle, lower parts kit, buffer tube, buffer, recoil spring, end plate, and castle nut. Lower receiver not included. You'll need to source a serialized lower receiver to complete the build. The adjustable carbine stock provides length-of-pull adjustment for different shooting positions and gear setups.
The 1/2x28 muzzle thread pitch supports a wide range of aftermarket muzzle devices and suppressors. The A2 birdcage flash hider is included, but the threaded barrel allows easy swaps for other configurations if needed.
Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Lower receiver not included.
