Faxon Firearms Match Series .223 Wylde Gunner Complete Upper - 16"

Drop-in precision for your AR-15 build — the Faxon Match Series .223 Wylde Gunner Complete Upper delivers a 416R stainless Match Series barrel, mid-length gas system, and MuzzLok patented timing muzzle device in a complete upper group that mates directly to any mil-spec lower, BCG and charging handle included.

The Faxon Match Series 16" .223 Wylde Gunner Complete Upper is a fully assembled AR-15 complete upper receiver group featuring a 416R stainless Gunner-profile barrel, mid-length gas system, Faxon SuperFinished M16 BCG, Breek Sledgehammer charging handle, and 15" Streamline M-LOK handguard.

.223 Wylde accepts both .223 Remington and 5.56 NATO in a single chamber, with tighter brass support than a standard 5.56 NATO chamber for improved accuracy potential — without the pressure concerns of shooting 5.56 in a .223 Remington chamber. The mid-length gas system delivers a softer, more consistent recoil impulse than carbine-length setups on a 16" barrel. The MuzzLok patented timing system locks muzzle device orientation with a reverse-thread jam nut — no crush washer, repeatable field removal and reinstallation without losing timing.

Compatible with any mil-spec AR-15 lower receiver. Accepts both .223 Remington and 5.56 NATO ammunition. Note: This configuration uses a fixed gas block and standard MuzzLok ported flash hider (1/2x28). This upper is not configured for suppressor use — for suppressor-ready builds, see Faxon Match Series variants with adjustable gas block and Plan B-compatible MuzzLok muzzle device.

416R stainless barrel with salt-bath nitride finish and NP3-coated extension provides corrosion resistance, reliable feeding, and easy cleaning. 5R button rifling reduces fouling and bullet jacket distortion for better consistency with match-grade ammunition.

Best for precision AR-15 builds, competition shooters, hunters, and anyone who wants Match Series accuracy and .223 Wylde ammo flexibility without sourcing and assembling individual components.

Faxon Firearms button-rifles and inspects every Match Series barrel in-house at their Cincinnati, Ohio facility, ensuring tight quality control across the complete upper lineup.
