Product Info for STNGR AR-15 5.56 NATO 14.5in M-LOK Complete Upper w/15in HWKXL Handguard, BCG & CH
This complete upper from STNGR delivers a full-length, suppressor-ready platform for shooters who want maximum velocity and a true rifle-length setup without the added paperwork. The 14.5-inch barrel is the go-to choice for patrol rifles, competition builds, and multi-purpose setups where you need the ballistic performance of a 16-inch barrel in a more compact package. This is ideal for duty use, 3-gun competition, or anyone building a lightweight rifle that still delivers full 5.56 velocity. The 15-inch HWKXL handguard extends past the muzzle for that clean, tucked look - perfect if you're planning to pin and weld a muzzle device to reach 16 inches or add a suppressor down the line.
The AT3 14.5-inch government profile barrel in 5.56 NATO pairs with a mid-length gas system for smooth, reliable cycling and reduced recoil compared to carbine-length systems. The STNGR HWKXL handguard is built from 6061-T6 aluminum with M-LOK slots at 3, 6, and 9 o'clock, plus QD sling points front and rear. At just 9.6 ounces, it keeps the weight down while giving you a full-length top rail and plenty of room to mount lights, lasers, and grips.
This upper comes fully assembled and ready to run - STNGR includes their phosphate chrome-lined M16 bolt carrier group with a C158 bolt and a standard GI charging handle. Built on AT3's slick side billet upper receiver with a low-profile .750 steel gas block, mid-length stainless gas tube, and KAK Slimline flash can. Available in Black, Flat Dark Earth, and OD Green to match your build.
