This premium, custom-built carbine is built on an elite Alexander Arms multi-caliber foundation (Serial Number: ALEXA-00040) and meticulously assembled and fit by professional gunsmith Brian Searcy. The rifle features a total build and labor value exceeding $4,300, representing an absolute zero-compromise approach to performance. Originally constructed as a 300 Blackout carbine, this high-end rifle features an Evolution Armory PVD DLC Ionbond finish for unparalleled wear and corrosion resistance. The fire control group features a match-grade Geissele 2-stage trigger with a crisp 4.5-pound pull weight, housed within a Seekins billet trigger guard. The lower receiver controls are further elevated with premium components, including a Battle Arms Development ambidextrous safety selector, a Seekins enhanced bolt catch, a Seekins billet magazine release, and a comfortable Fab-Defense pistol grip.
The rifle's precision architecture centers around a 16.2-inch Wilson 416R stainless steel barrel, featuring a 1:15 right-hand twist and a 6-groove design optimized for the hard-hitting 300 HAMR caliber. The barrel is surrounded by a 15-inch Seekins free-float KeyMod handguard, maintaining a sleek, modular profile while providing excellent heat mitigation. Reliability is driven by a precision carbine-length gas system regulated by a Seekins .750 diameter low-profile adjustable gas block. The action cycles flawlessly utilizing an ultra-slick, NP3+ coated Ambush Tactical Bolt Carrier Group (BCG) and a rugged Bravo Company charging handle. Finishing out this high-end tactical build is a heavy-duty Troy CQB stock and a Wilson Accu-Tac flash hider threaded to the muzzle. This professionally fit and assembled custom carbine delivers master-tier gunsmithing, premium coatings, and elite components into a single, high-performance package. Please see the photos.
