Product Info for STNGR AR-15 5.56 NATO 11.5in M-LOK Complete Upper w/13.5in HWK Handguard, BCG & CH
This STNGR 12.5in complete upper is built for compact AR-15 pistol or SBR configurations where maneuverability matters but you still want solid 5.56 performance. The 12.5in barrel with a carbine gas system offers a smooth recoil impulse compared to shorter gas setups, while the 1:7 twist stabilizes a wide range of common bullet weights. Paired with the 13.5in HWK M-LOK handguard and a full M16-profile BCG, this upper arrives fully assembled and ready to drop onto any standard AR-15 lower.![]()
