The 9,3 Jimbo was designed for the DPMS LR308 and ARMALITE AR-10 platform.  In addition, it is an ideal choice for the short action rifles such as the Remington Model 700, Remington Model 7, Savage Model 10 and any other bolt action sized for the 308 Winchester.

THE 9,3 Jimbo AR

On the 308AR (generic term describing the DPMS LR308 and ARMALITE AR-10), the 9,3 Jimbo requires only a barrel change.

  • Standard 308 Winchester Bolt
  • Standard 308 Winchester Barrel Extension
  • Standard Buffer and Buffer Spring
  • Standard Upper and Lower Receivers
  • Standard Carbine or Mid Length Gas System (16-22 inch barrels), or

On barrels, we find an 18-22 inch barrel is the ideal length range to give full combustion of the powder charge which will range between 40 and 50 grains for supersonic loads depending on the powder you use.  Using an even longer barrel will not provide additional benefit given the volume and burn rate of the ideal powders.   During testing, we have used  18″, 20″ and 22″ barrels.
