The Diamondback DB9R is a Versatile Pistol Caliber Carbine

Diamondback Firearms is an industry leader in AR-15 production, and now you can get all the advantages of an AR-15 combined with a more affordable pistol caliber! The Diamondback DB9R is chambered in the very popular and more affordable 9mm Luger cartridge, making it more affordable to shoot than standard 5.56 NATO AR-15 platforms. Additionally, because it uses double stack 9mm Glock pattern magazines, you may even have the option to interchange magazines with your sidearm! With a full length Picatinny top rail for mounting your choice of optic or sights and an M-LOK handguard, this AR-15 pistol is ready for you to customize in whatever way suits you. Diamondback's pedigree of creating high quality AR-15s speaks for itself, and the DB9R AR-15 pistol continues that legacy with some added innovations.
