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.
[2] 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.
