Oberland Arms BL M12 .223 Rem

The OA-15 BL M12 is the short-barrelled carbine of Oberland Arms’ Black Label line, built in Huglfing, Germany around a forged 7075 upper/lower receiver set and a Lothar Walther LW19 match-grade barrel. The 12.5″ barrel combined with the 11.5″ slim BL M-LOK free-float handguard yields a compact, highly maneuverable rifle intended for sport, defensive training, and authority use where overall length matters. Each rifle is ~95% custom-built to customer specification and ships with an OA M4 telescopic stock, the OA Muzzle Flash Device, and Oberland’s “new generation” golf-ball grip in two sizes.

Forged German Receiver Set

The upper and lower are forged from 7075-T6 aluminum in Germany and finished with hard black anodizing. Oberland’s tolerance standards and careful hand-fitting produce a receiver set that feels noticeably tighter than typical mass-production ARs.

Lothar Walther LW19 Match Barrel

Lothar Walther’s LW19 is one of the most respected match barrels in Europe. The 12.5″ version retains the match-grade bore uniformity that makes longer Lothar Walther barrels famous, in a package built for quick handling. The 1:7″ twist stabilizes heavy match bullets.

BL M-LOK 11.5″ Slim Handguard

The BL M-LOK slim profile handguard is free-floating and covers the gas block. Its reduced diameter is noticeably thinner than typical AR rails, making it comfortable to grip even for smaller hands, while still providing a full complement of M-LOK slots.

Hand-Built in Germany

Each OA-15 rifle is ~95% custom-specified by the customer and delivered in a lockable OA transport case.
