 KAC SR15 vs LaRue OBR accuracy

Just curious if anyone had any concrete information about the SR15 accuracy? I saw a review that said under 1.25" MOA at 100 yds for the SR15 was to be expected, but the OBR was sub-MOA. Is there any truth to this (the SR15)? I have not been able to find too much information on the topic (the larue has a lot, but not the sr15). Any help would be appreciated.

The OBR and the SR15 are two very different systems. The SR15 is not meant to be a tack driver.
Ammunition is always a variable.

I know this is does not answer your question about accuracy, but comparing the OBR and SR15 is comparing apples to oranges.

I think the most one could expect, from reading many reviews of chrome lined barrels, emailing companies in doing my research before making a buy, is 1.5-1.25 MOA. In shooting a 10-round group, this is very good accuracy. Keep in mind, this is going to be with match ammunition. Don't think you'll be there with Wolf.

On the same token, a good stainless barrel will typically be right at or under 1 MOA. The cost for this is decreased barrel life, and increased cost and weight. Again, you aren't going to get sub-moa groups on cheap ammo. If you're chasing mouse holes, be prepared to buy good ammo.

I have a stainless custom Noveske barrel on my rifle, and it shoots great and I love the gun. But stainless barreled guns aren't for everyone.

That being said, if I were to by a complete chrome barreled rifle, it would without a doubt be a SR15E3.

What is the SR15 designed for? To be a reliable piston weapon? I've looked everywhere, and I'm relatively new to the AR world, so I'm not up on everything, but I consider myself fairly knowledgeable.

I'd be using the gun scoped, for hunting at medium ranges (sub 200 yards). I really like the OBR, but I also like the taupe SR15. I figure that the SR15 is more of a "combat accurate" weapon vs the OBR being more like a semi auto sniper rifle. They both have good features and are within the same price range, so I thought they were similar in performance. I guess I was wrong. Any more info would be great, though.

The SR15 is more of a combat rifle...something you'll be fighting with from close quarters out to 300 yards or so. At 300 yards, 1.5 MOA accuracy is plenty when you're aiming at center mass on a human size target. It has a chrome lined barrel, which is what makes it less accurate than stainless, but also helps with durability...especially with higher rates of fire.

The OBR is what you would consider a precision rifle...commonly called a Recce in 16" form, or an SPR in 18" form. I don't know the exact weight of the SR15, but the OBR is undoubtedly going to be a bit heavier. This type of rifle is meant to get out a little further (maybe 500-600 yards), where 1.5 MOA might not be enough. With the OBR, you will likely be able get a little better than 1 moa with good ammo (I haven't shot an OBR, but my Noveske 18" SPR is better than 1 MOA and I'd expect the Larue to do the same). As someone mentioned, the stainless barrel is what makes the rifle more accurate, but the cost is barrel life and durability under a high volume of fire...something most of us will not subject our rifles to. I think the OBR is going to be a bit heavy for hunting...once you put a scope on it, you'll be lugging around 9-10+ lbs of gun...not ideal.

You may consider the ligher weight Larue PredatAR if you want something that's kind of a "happy medium" - plenty accurate (especially at 200 yards) and extremely light weight. With the PredatAR, you get a rifle with a light profile stainless barrel, which is designed to be more accurate than one with a chrome lined barrel, but they've trimmed a lot of the weight to make it just as light (if not lighter). At 6.25-6.5 lbs, I would imagine the Larue PredatAR is at least 1-1.5 lbs lighter than even the SR15. I would imagine you'll get 1 MOA accuracy out of the PredatAR...if not, it'll be pretty damn close. With that, you'll have a rifle that's light enough to hunt with, but accurate enough to shoot competitions if you ever decided to.

Bottom line, you just need to take into consideration weight, accuracy and barrel durability, and then find the one that meets your needs the best. If I were looking for a rifle I could hunt with, I think the PredatAR would be a very serious consideration.

You should also note....some high quality chrome lined barrels on the market can be just as accurate as some of the cheaper stainless barrels, so you can't always say that any stainless barrel will be more accurate than any chrome lined barrel.

The SR15E3 can be considered a product improvement over the standard AR15 design. It's not a piston gun, its still a DI design. There are quite a few enhancements in the design, in the gas system, bolt, and ambi features of the lower.

You can put any color furniture on the gun you want, plus you can always use one of the bake on finishes if you want a really tough durable finish.

Your assesement of combat accurate is pretty good, same with the OBR. They are really designed for different things. 1.5 MOA with good ammunition is plenty accurate. An inch and a half group at 100 yards is very good.

If you want a rifle for groups, and to lean more toward precision shooting, I think the OBR is the way to go.

If you want a great handling high round count weapon, I would go with the SR15E3.

This isn't to suggest the OBR isn't capable of shooting a lot of rounds. Both guns kind of overlap in capabilities, but one does precision better and the other does high round count better.

The SR15 e3, as stated before, is a great general purpose gun or SHFT weapon. It is reliable, smooth shooting, light, and more than accurate enough for general purpose/LE patrol and other similar roles. I will also say that we are releasing some new systems this year at SHOT that I believe you may find interesting especially for your hunting needs. If you head over to our Industry Section you will get a hint as to what is coming out.

I took a look over there and posted a question there. I had seen that thread before, but it looks like some other pictures and stuff have been added since. I will definitely take a look into your new productions, thanks for the heads up!

Accuracy, it's far better to have it and not need it, then need it and not have it.

Shoot all you want with a precision rifle, and some day, in the far, far future, you end up with "battle rifle" accuracy.

We are introducing a 18" Precision platfrom this year, with the E3 bolt.

The Larue 5.56mm (be it OBR 556 or PredatAR 556) guns are a different type of gun that the SR-15E3 Carbine. The SR-15E3 has a CHF Chrome Lined barrel, with the E3 bolt –– bascially you won't get tack driving accuracy gurantees –– but you will get a gun that the bolt and barrel are good for 20k rounds, which you will not get from the standard AR bolt with a Stainless Steel barrel.
While we has seen a few subMOA SR-15E3 guns, it was not designed to be that, and does not come with an accuracy guarantee of SUB-MOA.

At the end of the day its up to you the customer to decided what you want in a gun.

I agree and no bashing.
OP you picked top tier AR platforms this is like comparing Ciroc vodka to Grey Goose vodka. One if made from grapes the other grain and both are top shelf items just made a little different but will accomplish the same thing.

My .02 I would get the LaRue it is made in Texas and they are sweet rifles.

My point was if accuracy is his goal, that he would be better served by the Larue gun, or if he was not as desiring of accuracy but looking for a longer part life gun to get ours.

and Mark, did you get your hair cut yet hippy?
