The lower receiver is factory-marked ArmaLite Inc., Geneseo, IL, and carries the AWB-era law-enforcement restricted rollmark that collectors seek. The US-prefix serial range places it in the 1995–2004 period, adding clear historical context to this example.
Configured with a flat-top A4 upper receiver on an M15A2-marked lower, this carbine uses a carbine-length gas system with a round delta ring, a fixed A2 front sight base with a pinned sling loop, and a 16-inch M4-profile barrel capped with an A2 flash suppressor. The barrel is threaded, consistent with the installed A2 device.
The installed Troy carbine-length quad-rail handguard provides a rigid aluminum interface, while the detachable rear iron sight complements the fixed A2 front sight. Furniture includes a 6-position collapsible polymer stock offering a 10.35–13.5 inch length of pull and an A2 pistol grip.
Built on hard-anodized aluminum receivers, this AR-15 platform rifle is a semi-automatic, direct-impingement design chambered in 5.56mm NATO with a 30+1 capacity. It uses a STANAG-pattern magazine interface and retains the A4 upper’s forward assist and ejection port cover. Made in the USA, it blends AWB-era collectibility with a practical, updated top end.
