Currently all branches of the US Military purchase match 5.56mm ammunition from Black Hills. Law enforcement agencies nationwide rely on our ammo too. Jeff Hoffman has been a sworn officer since 1979. Before starting the business Jeff personally inspected the ammunition he carried on duty. Now every round of ammunition leaving the factory is hand inspected by our quality control staff. Firearms manufacturers use our ammunition for testing during development because we have a reputation for excellence. We currently sell to Armalite, Beretta, Browning, Cimarron, Colt's Manufacturing, Colt's Defense, DPMS, Dakota Arms, Detonics, FN, Freedom Arms, GA Precision, H&R 1871, Heckler and Koch, Iron Brigade Armory, Kimber, Landtee, Lewis Machine, Marlin, McMillan Brothers, Mossberg, Patriot Arms, Robar, Rock River Arms, Savage Arms, Sig Sauer, Smith & Wesson, Springfield Armory, Sturm Ruger, Texas Brigade Armory, and Wilson Combat. Dealers have been our foundation since the beginning in 1981. Generally speaking, Black Hills may not be the lowest cost ammunition available, but we do feel it is one of the best values. If the combination of precision made ammunition, excellent customer service and reasonable pricing appeals to you, then we'd be happy to add another discriminating customer.
