Armalite M15A4 5.56mm NATO Semi-Auto Rifle, 20 Inch Barrel, Flat-Top T-Marked Rail, A2 Stock, Custom Sights & Bipod
This Armalite M15A4 stands out with its 20 inch barrel, flat-top upper featuring a T-numbered MIL-STD-1913 rail, and forged aircraft-grade alloy receiver with a matte anodized finish. It is configured with a fixed A2 stock and rifle-length ribbed polymer handguard, and it includes practical upgrades: a clamp-on folding front sight, a detachable bipod, and a rubberized finger-groove pistol grip. The receiver carries the Geneseo, IL roll mark and the rifle comes with three 30-round magazines.
Built on the AR-15 platform with a direct impingement, semi-automatic action, this M15A4 combines classic A2 features with a versatile flat-top upper. Sights include a detachable A2-style rear assembly and a clamp-on folding front sight, giving the shooter flexible iron sight options. The rear sight body shows a diamond logo mark.
The 20 inch barrel is threaded and fitted with an A2 birdcage flash suppressor and crush washer. The upper includes a forward assist, case deflector, and ejection-port dust cover. The rifle-length, two-piece ribbed polymer handguard provides a secure, traditional grip surface.
Ergonomics are anchored by a fixed A2 buttstock with trapdoor buttplate and a rear sling loop. The rubberized finger-groove pistol grip with logo medallion enhances purchase, and the length of pull measures 14.0 inches. A manual safety is standard.
This rifle accepts AR-15 pattern magazines and has a stated capacity of 30+1. It is made in the United States and retains the hallmark Armalite markings from Geneseo, Illinois.
