LaRue Tactical 20" 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.

Barrels:
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.

Internals:
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.

Furniture:
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.

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.

    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. Dave Clark Houston, TX

    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.

    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 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.

    I've had my 5.56 OBR w/ 20" barrel for 2-3 years. I brag about it so much, I feel guilty. Now I just wait til they ask, and then I just say LaRue. If they know gunns, they usually OOH and AHH. I shoot FT/R 200 yd prone, and so far my best is a 600-42X, but I'm not a very good shot. A friend of my son, who is a good shot, on his first 5 shots with my rifle got a .72" group at 200 yd. (That's .344 MOA from an AR!) I also have a NightForce 8-32x56 NXS scope on it using a LaRue mount of course. (if you can't see it, you can't hit it.)

    I bought this rifle and outfitted it for the first trip to the range on 3/29/14 a few miles north of its birthplace in Texas. Installed the OBR base with a Leupold VX-6 2-12 riflescope. The base is fantastic and returned to zero exactly as specified. Leupold optic is clear and a work of art. I shot from a concrete bench rest at 100 yds using the Atlas bipod on the front and a sandbag on the back. I could not get Federal Gold match 77 gr ammunition, but I shot 5-shot groups with four different types of Match ammo: 1. Norma 223 match with a Sierra MatchKing 77 gr BTHP bullet. Results were excellent and within 1" group size. 2. Right to Bear Arms with a 75 gr BTHP bullet. Results were ok, but were not as good as the other three rounds I shot. I saw some vertical stringing, which usually indicates to me powder charge variability. However, laterally, it was as good as any ammo I shot. 3. Hornady 223 Rem 75 gr BTHP Superformance® Match™. Results were excellent and within 1" group size. 4. Federal Gold Medal Match 69 gr. Apparently the little brother to the round LaRue used for test firing. It did extremely well and within 1" group size. Based on my initial test results, I am very pleased with this rifle. However, I am just getting started with it, and most of my experience is with bolt-action rifles. This is my first project with an accurate AR-15, but I am having a lot of fun! I recommend this rifle to any and all. It is a work of art, it is accurate, and I am proud to own it.

    Outstanding rifle as others have said. I already have two carbines (Colt LE6920 and Noveske N4 300 BLK), so a 20” rifle was the next logical choice for me. I was looking for a “designated marksman” capable rifle. I put a US Optics 1.8X10 scope with Larue LT111 mount on mine. Its a great package capable of perimeter control, CQB, varmint, predator, hog hunting, etc. The goal was to push a 77 grain tactical bullet at 2800 fps or more, and keep it accurate. This would equal or exceed the the power/energy of the 300 BLK and shoot much flatter. This rifle does this easily and does not exceed published 5.56 maximum hand loads. So far, I have worked up loads using 77 SMK, 77 Berger OTM TAC, and 75 Swift Scirocco’s. I used reworked Lake City brass, Ramshot TAC powder, and CCI #41 primers. All three of the above loads shot sub 1/2 MOA 5 shot groups with cold/warm barrel. The groups opened up a bit as the rifle got hot but all stayed within 1 MOA. The Swift’s edged the other two in accuracy and would no doubt make a good hunting or tactical bullet. I have used them in .308 and 270 on large game and they shoot and perform flawlessly. Accurate Arms publishes load data for full power 5.56 NATO. Back to rifle; I have never owned an AR with the precision and innovation of the Larue. Continuous one piece top rail, bolted receiver/hand guards, hard chrome bolts, LC50 barrel steal, etc. They are just a cut above the rest in form, fit and function. Of course the selectable gas block means a suppressor is next on the agenda. Why blow out your ears when shooting O-Zombies? I seriously considered the 7.62 OBR. I already have a precision tactical 7.62 bolt gun. But, I like to shoot a lot and the 5.56 just made more sense for me. Someday. You won’t regret owning any of the Larue AR's

    What can you say that has not already been said. Excellent rifle. I have the 20" barrel 5.56 OBR and have had no problems with it. Very accurate and works well suppressed. The only problem was the 16 month wait to receive it. This rifle has become my favorite over an H&K and an LWRC.

    Words fail me to express how much I love this rifle. I did many hours of research before I bought this, and could have bought about any rifle in this class. I expected a lot, but the OBR 5.56 surpasses my expectations in every way.

    I have to say that everything that I have purchased from Larue has been top of the line. However, the 20" barrel OBR is a spectacular rifle. The only change I made was to add a Magpul fully adjustable stock. I mounted a Leupold 8.5 - 20 from another rifle, using one of Larue's great detachable mounts. I then took it to the range where I shot 2 shots to confirm the zero and then moved to 100 yards for 3 more shots and then to 200 yards. Being experienced (another word for old) my shooting is not perfect, but I was able to three times put 20 of the 52 gn Sierra match bullets into a 1" group including fliers. One of my 10 shot groups measure .6". I shot the rifle 255 times with no issues at all. I am planning to try and wear the barrel out. Paul Turner, Salem, Oregon.
