.223 Wylde Chambering

.223 Wylde offers a hybrid chamber design optimized for both .223 Remington and 5.56 NATO ammunition. The chamber dimensions provide enhanced accuracy with .223 Remington while maintaining full compatibility and safe pressure handling with 5.56 NATO loads.

SB Tactical SBA5 Brace

The SB Tactical SBA5 pistol stabilizing brace features nylon reinforced polymer construction with adjustable positioning. The brace pairs with the included mil-spec heavy-duty 6-position buffer tube, buffer, carbine recoil spring, castle nut, and end plate.

Trinity Force KMX Keymod Handguard

The Trinity Force KMX 12-inch Keymod handguard provides freefloat design with 6061-T6 aluminum construction, hard coat anodized finish, and modular Keymod slots for direct accessory mounting. The freefloat design isolates the barrel from external pressure, supporting accuracy.

QPQ Nitride Bolt Carrier Group

The 5.56x45mm bolt carrier group features QPQ nitride finish over 9310 alloy steel. The nitride treatment provides corrosion resistance and surface hardness while reducing friction.

This full build kit is compatible with mil-spec AR-15 lower receivers. All components use standard AR-15 specifications and threading, including the 1/2x28 TPI muzzle threads matching the included steel flash can.
