LaRue Tactical OBR 5.56 Overview:
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 7075-T6, 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.

Barrels:
The barrels are LW-50 stainless steel in 12”, 16.1", 18" & 20" lengths. They are Wylde chambered, and feature polygonal rifling in a 1/8 twist rate. We have used these barrels with great success for years in our popular and accurate Stealth uppers. LW-50 Stainless has proven itself for over 15 years, in military and civilian uses ranging from sniper, tactical, target, and other high-performance applications where long life and accuracy are critical.

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.

Internals:
The Bolts and Bolt Carriers are hand-polished hard-chrome with max-staked carrier keys. The carrier key contact areas are surface-ground flat for zero gas leakage. The trigger group is the same excellent Geissele SSA Combat Triggers we use in the OBR 7.62.The SSA provides an average 4.5lb pull weight.(2.5 lbs on the first stage and 2lb on the second stage).

Furniture:
The 12”, 16”, 18", and 20" models come with a 6-position Magpul CTR and LaRue medium A-PEG™ Grip. The 20” Model Comes with an A2 Stock, in black.
