Wylde Card 11.5-Inch Carbine-Gas 1:8 .223 Wylde AR-15 Free-Float M-LOK Handguard Pistol Full Build Kit with Gauntlet Arms Brace
The Wylde Card Full Build Kit is built around an 11.5-inch .223 Wylde barrel machined from 4140 chrome moly vanadium steel in a government profile, with a carbine-length gas system and a black Nitride finish. It is paired with a 10-inch black free-float extended quad rail handguard in a clamp-on design and a nylon-reinforced polymer stabilizing brace. The kit ships with a complete bolt carrier group and a mil-spec M4 charging handle. The short barrel keeps the front end compact and quick to handle, and the 1:8 twist suits a wide range of bullet weights in .223 Wylde. Lower receiver is not included. Lower parts kit, pistol grip, pistol buffer tube, buffer, recoil spring, castle nut, and end plate details were not supplied with this listing.

Barrel and Gas System
The 11.5-inch barrel is machined from 4140 chrome moly vanadium steel in a government profile and finished in black Nitride, a surface treatment that adds hardness and corrosion resistance while leaving a clean, matte black look. Its 1:8 twist rate and .223 Wylde chamber make it suited to a wide range of bullet weights. The barrel is set up for a carbine-length gas system with a .750-inch gas block size, and the muzzle is threaded 1/2x28 for a compatible muzzle device.
Upper Receiver and Handguard
The upper receiver is machined from 7075-T6 aluminum with M4 feed ramps and an anodized finish, giving it a hard, wear-resistant surface that holds up to regular handling. It is paired with a 10-inch black free-float extended quad rail handguard that attaches with a clamp-on design. As a free-float handguard, it leaves the barrel free of handguard contact, while the extended quad rail layout gives the builder Picatinny mounting surfaces on multiple sides for optics, lights, grips, and other accessories.
Bolt Carrier Group and Charging Handle
The included complete bolt carrier group is rated for 5.56, .223, .300 Blackout, and .350 Legend, with a carrier machined from 9310 alloy steel and finished in Nitride, a surface treatment that adds hardness and corrosion resistance and helps the carrier stand up to repeated cycling. Paired with it is a mil-spec AR-15 M4 charging handle, completing the upper so it is ready to be matched with a compatible lower receiver.
Brace
A black stabilizing brace molded from nylon-reinforced polymer is included. Buffer tube compatibility details for the brace were not supplied with this listing and should be confirmed before purchase.
