The PSA Guardsman-15 16″ Midlength 1:7 CL Phosphate 15″ MLOK Upper with BCG & CH is a high-quality, American-made AR-15 upper receiver assembly built for reliability, durability, and performance. This complete upper features a premium 16-inch chrome-lined, phosphate-coated barrel chambered in 5.56 NATO, paired with a mid-length gas system for smoother cycling, reduced recoil, and excellent reliability—ideal for duty, home defense, training, or recreational shooting.
Crafted from 4150V Chrome Moly Vanadium steel, the tapered-profile barrel offers a 1:7 twist rate that stabilizes a wide range of bullet weights (55-77 grain), an M4 barrel extension, .750″ gas block journal, pinned low-profile gas block, and standard A2 flash hider on 1/2-28 threads. The barrel is fully chrome-lined for superior corrosion resistance and longevity.
The upper is topped with PSA’s 15″ Guardsman Hex Full Picatinny M-Lok free-float handguard, providing a rigid platform with full top Picatinny rail for optics and ample M-Lok slots at the 3, 6, and 9 o’clock positions for accessories like lights, grips, or bipods—enhancing accuracy by eliminating barrel contact.
The forged 7075-T6 A3 flat-top upper receiver is machined to mil-spec tolerances, hardcoat anodized for maximum durability, and includes a forward assist and dust cover. It comes complete with a full-auto profile BCG (8620 steel carrier, phosphate-coated and chrome-lined, with shot-peened, HPT/MPI-tested Carpenter 158 steel bolt, Sprinco gas rings, properly staked gas key) and a standard charging handle.Proudly manufactured in the USA to mil-spec standards, this upper delivers exceptional value with proven components for consistent performance.
