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 Stainless Steel in 12”, 16.1", 18" & 20" lengths. They are Wylde chambered, and feature polygonal rifling in 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.
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”, and 18" models come with a 6-position Magpul CTR and LaRue medium A-PEG™ Grip. The 20” Model Comes with an A2 Stock, in black and LaRue medium A-PEG™ Grip.

XTRAXN™ is a proprietary chamber feature added to reduce frictional forces
caused by pressure-expanded cartridge cases bearing against chamber walls.
Facilitates reliable extraction through a wide range of temperature / chamber
pressure extremes. XTRAXN™ extends extractor life, while having no effect on the
firearm's accuracy. All this, and it dovetails well with the OBR's world-famous
accuracy.
Guaranteed sub-MOA accuracy (with Federal GMM, 77 grain ammo)
Proprietary handguard design keeps the rifle cool, aids in accuracy and ease of handling
Unique fully freefloating barrel and barrel-nut design, that does not touch the handguard at any point, aids in accuracy
Upper, lower and rails are CNC-machined from 7075-T6, Type-III hard anodized
10 MOA built into a continuous, T-marked, 1-piece upper rail
Drop-down at rear of rail, for zero MOA when using iron sights

I got the 20". Build quality-excellent. No wobble between upper and lower, yet the pins don't require a steel punch to drive out like certain other ultra-accurate ARs. I thought I would be bothered by the dual-stage trigger (I normally use single-stage), but I found it to be extremely consistent and a non-issue. This gun does not move. Super steady, even in rapid strings. The accuracy is exceptional. I got a .42 MOA group at 104 yards with Black Hills mk262. That was using MBUS sights. When the rifle can shoot a tighter MOA group than the MOA width of the sight, you know it's a good rifle. You get more than what you pay for. Top-notch rifle. If you are considering one, do not hesitate any further. Get it.
If you are in the market for a cheap, piece of crap AR - by ALL means DON'T by this rifle, as you will be grossly disappointed..!!! However, if you are in the market for a top tier rifle that is very solid, (as Mr. Clark pointed out), is of exceptional quality, and can split a needle (driving tacks is too easy) at 300 yards - buy this baby. She will do you right in every aspect. When you look at it, you see the highest level of craftmanship, go crazy - pick it up and you will FEEL the highest level of craftmanship, shoot it and you will experience the highest level of craftmanship. Mark and his team has built the perfect rifle. Just don't tell them they need to charge twice as much, because I'm getting ready to get the 7.62 version..!!!

I've had my OBR 5.56 for six months now and it continues to exceed my expectations. I researched every AR on the market and held most of them. The LaRue OBR 5.56 is the most solid, accurate weapon I've found.

Best AR on the market at any price. I will be purchasing the 7.62 at tax time. Special thanks to the support team who were very patient and helpful during the decision process, even after I changed the order slightly 2 weeks after placing my original order.
God Bless our troops!
