American Tactical's Alpha-15 gets its 5.51-pound weight from reinforced polymer receivers, a 16-inch pencil-profile barrel in 4150 chrome-moly vanadium steel and a carbon fiber infused buffer tube. It is a semi-automatic AR-15 pattern rifle chambered in 5.56 NATO, which also fires .223 Remington, with a 1:8 twist, a full-length top Picatinny rail, an 8-inch M-LOK handguard and flip-up sights. One magazine, an adjustable buttstock, an A2 grip and a two-position manual safety complete it.

At this weight it is an easy rifle to carry all day, which is where it fits for an Oregon buyer. Under the 2026 rules a centerfire of .22 caliber or larger is legal for deer, so 5.56 qualifies, but a hunting semi-automatic may not hold more than five rounds, so you would run a five-round magazine for the western Oregon general buck season, October 3 to November 6. Elk requires .24 caliber or larger, which rules this cartridge out. The rail takes a scope or red dot when you want one.
