New! STNGR AR-15 .300 Blackout 10.5in M-LOK Complete Upper w/13.5in HWKXL Handguard, BCG & CH Up to 33% Off w/ Free S&H — 3 models

This complete upper from STNGR delivers a purpose-built 300 BLK platform for shooters who want maximum versatility in a compact package. The 10.5-inch barrel is the sweet spot for 300 BLK - whether you're running supersonic loads for hunting and home defense or subsonic rounds with a suppressor for quiet work. This is the foundation for suppressor hosts, hunting rifles, and close-quarters setups where you need hard-hitting performance without the length. The 13.5-inch HWKXL handguard extends past the muzzle for that clean, tucked look - perfect if you're planning to add a suppressor down the line.

The AT3 10.5-inch medium profile barrel in 300 BLK pairs with a pistol-length gas system for reliable cycling with both supersonic and subsonic ammunition. 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 8.7 ounces, it keeps the weight down while giving you a full-length top rail and plenty of room to mount lights, lasers, and grips. The KAK 5-inch extended flash can gives you extra length to fill the handguard and redirect concussion forward.

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 and pistol-length stainless gas tube. Available in Black, Flat Dark Earth, and OD Green to match your build.
