LaRue Tactical 12" OBR 5.56 Overview:
View Individual State Variances
Building off the success of our highly-accurate and reliable OBR 7.62, we set out to apply the same proven design features into a 5.56 rifle. The result is a lightweight, and reliable, tack driver that remains cool…even after high-rates of fire. The barrel and barrel nut does not touch the handguard at any point, so there is very little heat-transfer to your support hand. Like its 7.62mm sibling, both the upper and lower are CNC-machined from billet aluminum, for the optimum fit and consistency...translating into maximum accuracy. Even though this is a complete rifle, the upper will fit to any Mil-Spec AR15/M16 type lower.
The continuous upper-rail provides plenty of room for weapon-mounted night-vision day/night combinations and provides correct ballistic orientation for all inline night-vision combinations. The 10 MOA cant gives users an added advantage when using magnified optics at longer distances. A step-down at the rear of the receiver creates zero MOA for use of BUIS’s at shorter distances.
Each rifle ships with three, 3” long, MIL-STD-1913 detachable rail sections that they can be configured anywhere along the entire length of the handguard (via threaded steel inserts), for the interface of MIL-STD-1913 equipped lights, lasers, bipods, grips, tripod mounts, etc.
The barrels are available in 12”, 16.1", 18" & 20" lengths. They feature a 1/8 twist rate. All barrels are threaded in ½ x 28, with an A2 flash hider attached (other muzzle devices can be added at an additional cost). The 12” model have carbine-length gas systems, the 16” and 18” models have a mid-length, and the 20” has a rifle-length. All gas blocks will 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.
The Bolts and Bolt Carriers are hand-polished hard-chrome with staked carrier keys. The carrier key contact areas fitted to allow 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.
The 12”, 16”, and 18" models come with a LaRue RAT Stock and LaRue medium A-PEG™ Grip. The 20” Model Comes with an A2 Stock, in black and LaRue medium A-PEG™ Grip.
