Product Info for STNGR AR-15 5.56 NATO 11.5in M-LOK Complete Upper w/13.5in RPTR Handguard, BCG & CH

This STNGR 12.5in complete upper is configured for compact AR-15 pistol or SBR builds using a carbine-length gas system for reliable cycling in shorter barrel setups. The 1:7 twist 5.56 NATO chamber handles both 5.56 NATO and .223 Rem ammunition, making it a flexible option for training or defensive use. The 13.5in RPTR M-LOK handguard provides extended rail space and a rigid lock-up with integrated anti-rotation tabs that interface cleanly with the billet upper receiver.image
