SI DEFENSE DPMS LR-308 15.5 JP VTAC Build

This 308 AR rifle build is an intermediate stage of another project. The plan is to use a matching SI Defense Generation II Upper and Lower Receiver, but at this time the lower is not in my possession. So for curiosity sake I took the SI Defense Upper and installed it on my DPMS LR-308 Lower from my DPMS LR-308 Precision Rifle Project on this site.

The upper consists of the following hardware:

  • SI DEFENSE GENERATION II STRIPPED UPPER RECEIVER
  • DPMS 308-BL-SASS 18″ FLUTED BARREL and MATCHING SASS GAS BLOCK GB-SASS
  • JP/VTAC¬† JPHG-6D JP Modular Hand Guard, Extra Long 15.5
  • DPMS 308-BCA Bolt Carrier Group
