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.

Barrels:
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).

Internals:
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.

About LaRue Firearm Accuracy:
LaRue accuracy is known world-wide. The accuracy of each LaRue Rifle is proven at our 100-yard tunnel using match-grade ammunition. No LaRue firearm can leave the facility unless it obtains accuracy of less-than 1 MOA (1.047”) at 100 Yards. Each firearm ships with a copy of a 3-round group obtained from that actual firearm. While we guarantee the rifle is capable of sub-MOA accuracy, we can not guarantee the end-user will be able to shoot sub-MOA…since we have no control over shooting proficiency, familiarity with the system, ammunition choice, environmental factors, etc. LaRue firearms are precision instruments that require discipline, training, proper ammunition and maintenance to yield the best results.

Furniture:
Base Model comes complete with A2 Rifle Stock and LaRue medium A-PEG™ Grip, A2 Flash Hider, plus two LaRue-made 20-round magazines.
