Faxon Firearms Match Series Gunner Complete AR-15 Upper Receiver - .223 Wylde - 16"

The Faxon Firearms Match Series Gunner Complete AR-15 Upper Receiver in .223 Wylde at 16" pairs a 416R stainless barrel with a mid-length gas system and Faxon's patented MuzzLok timing muzzle device, ready to mate directly to any mil-spec lower.

Features:

• 16" 416R stainless Gunner-profile barrel, 5R button rifled, salt-bath nitride
• .223 Wylde chamber, accepts .223 Rem and 5.56 NATO
• Mid-length gas system, fixed .625" low-profile gas block
• Faxon MuzzLok ported flash hider, nitride, 1/2x28
• 15" Faxon Streamline M-LOK handguard
• Faxon SuperFinished 5.56 M16 BCG, nitride (included)
• Faxon Edition Breek Sledgehammer charging handle (included)

.223 Wylde's tighter chamber geometry improves accuracy potential with match-grade .223 Remington while still safely accepting mil-spec 5.56 NATO, and the MuzzLok's reverse-thread jam nut locks muzzle device timing without a crush washer for repeatable field removal. This configuration uses a fixed gas block and standard MuzzLok flash hider rather than a suppressor-tuned setup — see Faxon's adjustable-gas Match Series variants for suppressor-ready builds.

The 416R stainless barrel's NP3-coated extension adds corrosion resistance and reliable feeding, and the 5R rifling reduces fouling and bullet jacket distortion for better consistency with match-grade ammunition.

Faxon Firearms manufactures and assembles every barrel in-house at its Cincinnati, Ohio facility, keeping quality control in-house from rifling through final inspection.
