.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 SBA3 Adjustable Brace

The SB Tactical SBA3 adjustable pistol stabilizing brace provides five positions of length adjustment. The brace pairs with the included mil-spec heavy-duty 6-position buffer tube, 3 oz 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 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 bolt head and 8620 alloy steel body. The nitride treatment provides corrosion resistance and surface hardness while reducing friction.
