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 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).
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
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.
Base Model comes complete with A2 Rifle Stock and LaRue medium A-PEG™ Grip, A2 Flash Hider, plus
two LaRue-made 20-round magazines.
Beyond accurate, making ragged holes is the norm. Upper and lower fit together like a single piece. I've never seen another AR made like this. I have another "top tier" AR, but it really isn't. LaRue is top, everything else is just further and further away. I absolutely love my OBR!
