JP Enterprises AR-10 MK III Free Floating Modular Hand Gaurd DPMS LR 308


Rainier Arms Free Ground Shipping

Manufactured as ever to the uncompromising JP standard, the MK III system is the final word on modular design fusing simplicity and utility with the benefits of both:


  • New, patented attachment method dramatically improves structural integrity while allowing for perfect alignment to bore axis comparable to one-piece, monolithic systems
  • The only forend system other than monolithics to offer top rail continuity, allowing bridging of the receiver and hand guard rail with optical mounts
  • Barrel nut redesign allows for easier and faster barrel installation or replacement
  • Internal barrel retainer nut serves as a lifetime component that doesn't distort like one-piece, one-time-use aluminum barrel retention nuts
  • Unified nut design accepts both the iconic, rock-blasted JP Signature and practical Rapid Configuration tubes with new knurled finish and allows for easy change between them
  • Easily interchangeable tubes with rapid re-indexing
  • Standard, readily available 10-32 screws for rail attachment less limiting compared to the problems of proprietary hardware

Machined from 6061 T6 aluminum with a 4140 steel barrel nut, this mid-length hand guard includes two JPHGS quick-detach sling studs.
