Wylde Card 11.5-Inch Carbine-Gas 1:8 .223 Wylde AR-15 Free-Float M-LOK Handguard Pistol Full Build Kit with SB Tactical SBA3 Brace
The Wylde Card Full Build Kit is built around an 11.5-inch .223 Wylde barrel machined from 4140 chrome moly vanadium gun steel in a government profile, with a carbine-length gas system and a Nitride finish. It is paired with a black free-float extended quad rail handguard and an SB Tactical SBA3 adjustable pistol stabilizing brace. The kit includes a mil-spec quality M4 charging handle, a 3-ounce buffer, and a standard AR-15 carbine recoil spring. 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. Bolt carrier group, lower parts kit, pistol grip, buffer tube, 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 gun steel in a government profile and finished in 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 runs a carbine-length gas system through a micro low-profile gas block sized for the .750-inch barrel diameter, and the low-profile block helps it sit cleanly beneath a free-float handguard. At the muzzle, 1/2x28 threads carry the included AR-15 TPI GI birdcage flash hider.
Upper Receiver and Handguard
The upper receiver is machined from 7075-T6 aluminum with an anodized finish, giving it a hard, wear-resistant surface that holds up to regular handling. It is paired with a black free-float extended quad rail handguard. As a free-float design, 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.
Charging Handle and Buffer System
The kit includes a mil-spec quality AR-15 M4 charging handle. The buffer system pairs a 3-ounce buffer with a standard AR-15 carbine recoil spring.
Brace
An SB Tactical SBA3 adjustable pistol stabilizing brace is included. It is designed to slide onto and adjust along a mil-spec carbine buffer tube. Buffer tube type was not supplied with this listing and should be confirmed before purchase.
Compatibility
This kit is built for AR-15 lower receivers and .223 Wylde builds. Bolt carrier group, lower parts kit, pistol grip, buffer tube, castle nut, and end plate inclusion, as well as feed ramp style and ejection port door and forward assist configuration, were not supplied with this listing and should be confirmed before purchase.
