Mark LaRue founded the machine shop that, in 1980, evolved into LaRue Tactical. His extensive background in precision machining has paid great dividends in terms of his understanding of what it takes to control and maintain the quality of his AR builds.
LaRue Tactical’s AR rifles can be broken down into four broad categories: the Optimized Battle Rifle (OBR), the PredatAR, the PredatOBR and the Costa Edition 5.56. The OBR, PredatAR and PredatOBR come in models chambered for 7.62mm NATO and 5.56mm NATO, with various barrel lengths available. The Costa Edition is currently available only in 5.56mm NATO. Each category of LaRue rifle is intended to accomplish a specific goal.

LaRue OBR

Intended as an “Optimized Battle Rifle” and chambered in 7.62mm or 5.56mm, the OBR features LaRue’s newly designed upper receiver and proven lower-receiver design. Both the upper and lower are CNC-machined from 7075-T6 billet for consistency and strength. The continuous upper rail provides plenty of room for mounting night-vision day/night combinations, along with correct ballistic orientation for all in-line night-vision combinations. The 10-MOA cant gives users an advantage when using magnified optics at longer distances. The Mil-Std-1913 side rails on the forend are detachable so that they can be configured for mission-specific gear or left off. The forend’s bottom rail also is detachable and can be positioned anywhere along the entire lower length to interface with Mil-Std-1913-equipped bipods, grips, tripod mounts and so forth. These rails are offered as spare parts for field-service replacement, thus keeping repair cost at a minimum.
The OBR’s barrels are stainless steel and offered in several lengths. The LaRue gas blocks feature Port Selector Technology (PST), which includes a two-point adjustable gas selector and allows optimum function in suppressed and unsuppressed modes with the flip of a switch. The barrel and barrel nut do not touch the handguard at any point, so there is very little heat transfer to your support hand. The result is a reliable, highly accurate rifle that remains cool even after high rates of fire.
