LaRue Tactical OBR 7.62 Rifle

  • Sale
  • MIL/LE


The LaRue OBR (Optimized Battle Rifle) was built from the ground up, using a newly designed upper-receiver platform, combined with a lower, inspired from our successful 5.56 MM lower. Both the upper and lower are CNC-machined from billet, for the optimum fit and consistency. The receiver components are designed with more material in critical areas to alleviate known issues of weakness in 7.62 platforms and to stiffen the receiver, translating into maximum accuracy.

The upper-rail provides generous room for all issue weapon-mounted night-vision day/night combinations (suitable for 7.62 MM). The built-in 20 MOA cant provides correct ballistic orientation for all inline night vision combinations. The MIL-STD-1913 side rails are detachable, so that they can be configured for Vis / IR illuminators, etc, or left off to keep rails pristine, without the need for bulky rail covers. The bottom rails are also detachable, and can be positioned anywhere along the entire lower length, for the interface of MIL-STD-1913 equipped bipods, grips, tripod mounts, etc. These rails are offered as spare parts for field-service replacement, keeping repair cost at a minimum.

Available in 16.1", 18" & 20" lengths. All gas blocks feature our unique Port Selector Technology (PST), a two-point adjustable gas selector that allows optimum function between suppressed, and unsuppressed operation at the flip of a switch. All barrels are threaded in 5/8 x 24, with an A2-type flash hider attached (other muzzle devices can be added at an additional cost). 

Suppressor Compatibility:
LaRue 7.62 rifles with Port Selector Technology (PST) have been optimized for best-performance with SureFire suppressors. We understand that there are dozens of 7.62 suppressors to choose from on the market at this time. We feel that SureFire suppressors fall somewhere in the middle-range in regards to effect of performance with gas-operated rifles. Many users have met with success operating different models of their choice. Combined with variables in ammunition, 7.62 suppressor owners have experienced a large spectrum of conditions (much greater than seen with 5.56 suppressors). This range of variables is easy to manage with a bolt-action 7.62, but with a gas-operated system it is not. While we made a concerted effort to design a gas system that will work with a wide range of suppressors, we can not guarantee proper-function with suppressor hardware other than SureFire. 

The Bolts and Bolt Carriers are hand-polished hard-chrome with staked carrier keys. The carrier key contact areas are designed for zero gas leakage.
