LaRue Tactical PredatOBR 5.56
View Individual State
The PredatOBR 5.56 was designed for those who are searching for a hybrid cross
between the standard OBR and PredatAR 5.56x45 Rifles. The most remarkable feature of the PredatOBR is its ability to be completely
“broken down” and stored into the optional Rollup Bag and Toolbox. The PredatOBR
handguard has a locking stainless steel QD Lever system on each side. Once the
levers are released, the handguard slides off of the upper assembly in seconds.
The PredatOBR's barrel can easily be removed with the supplied PredatOBR Barrel
Wrench, unscrew the Barrel Nut from Receiver and pull the Barrel Assembly free
from Receiver. No need to remove the gas tube, gas block or muzzle device.
Reverse the process to reinstall. Hand-tighten Barrel Nut and torque
approximately 1/8-turn past hand-tight (Approximately 40-50 foot pounds). Once
reassembled correctly, the point of impact (POI) shift will be 0.0 to 0.5 MOA of the original.
PredatOBR barrels are chambered in 5.56x45mm, and feature rifling in a 1/8 twist
rate. All muzzles are threaded in 1/2 x 28. Like the OBR and PredatAR riles,
LaRue has eliminated the conventional AR barrel nut and bolt the handguard
directly to the proprietary upper receiver, creating a true “free-float” barrel.
The handguard does not touch the barrel or barrel nut at any place. The zero-MOA
upper rail provides plenty of room for weapon-mounted night-vision day/night
combinations. Both the upper and lower are CNC-machined from billet aluminum for
the optimum fit and consistency. Even though it has been lightened certain
features, there is still additional material in strategic areas to achieve
The PredatOBR has threaded stainless-steel hard-points over the entire length of
the handguard at the 3, 6, and 9 o’clock positions. These hard-points have an
integral spine built-in for structural support. Provided with the system are
three 3-inch MIL-STD-1913 rail sections that can be positioned anywhere along
the handguard, per operator preference. These rail sections are
attachable/detachable using a supplied tool (Torx® T-15 wrench). The rail
sections are CNC-machined from billet aluminum. This robust solution provides a
perfect precision mounting space for aiming lasers, illumination and bipods.
The PredatOBR's Port Selector Technology™ (PST) gas block is adjustable, to aid
in the optimum function when using a sound suppressor. This special gas block
contains a dual port mechanism that is operated by rotating a lever from one
side to another. When the lever is rotated to the right-side of the rifle, the
gasses are reduced, to compensate for the extra blowback created by the
suppressor. When rotated to the left side, the gasses are increased for use
without a suppressor.
The LaRue Tactical 6-position Retract Action Trigger (R.A.T.) Stock comes
standard with every PredatOBR. It is ergonomic, has protected control surfaces
and contains a set of cleaning rods in an internal compartment. Since the height
of the 12 o’clock rail is at the optimum position, there is no need for a cheek
riser as part of this system. The New A-PEG grip also comes standard. This grip
was designed to be ambidextrous and places the hand in the corrected position
for precision shooting.

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.
