The goal of the Crazy Horse rifle project was to offer current military units a reliable and cost-effective modernization program for Squad Designated Marksmen (SDM) using existing M14 rifles in inventory. The Crazy Horse rifle was designed in conjunction with the Picatinny Arsenal and the Army Infantry School. Although the rifle has many "precision" features built in to make it accurate, it is not a sniper rifle and was designed as a battle rifle to fit the needs of the Army's SDM program.
The Crazy Horse rifle is built by Smith Enterprise Inc. and is used by various units within the US Military as the M21A5 and the M14SE. The Crazy Horse's metal components are cryogenically treated prior to assembly, which eliminates the need for bedding the stock with fiberglass and steel inserts. Additional upgrades include a completely adjustable trigger system (from 2.5 to 5 lbs) and an extended bolt handle for use in extreme cold environments.
The chamber is hand cut using chamber reamers specially designed for the M118LR round. Smith Enterprise Inc. is the only civilian rifle builder who uses these reamers. The gas system is unitized and hardened via Melonite. The gas piston is hard chromed to tolerances to ensure a precision fit within the hardened gas cylinder. Unlike traditional M14 rifles, the front sight is mounted on the gas lock as opposed to the muzzle to allow use of a direct-connect sound suppressor that mounts to the Vortex Flash Hider.
The scope is mounted to the rifle using a SEI scope mount and ring package made via electrical discharge machining (EDM). The scope mount is attached to the rifle's stock and not welded to the receiver.
