Accuracy fluke ?

[Rex colt]

Hello I was wondering if anyone would be able to answer my question. I have a AR chambered in 556 that shoots extremely good but from what I heard the barrel isn't a super precise barrel. Although I am able to obtain .36 moa groups with it. The barrel is a Danial defense light weight cold hammer forged chrome lined barrel on a standard arrow upper. From most accounts I hear this barrel should only be capable of around 1 MOA. I was just wondering if I got a fuke barrel that is extremely accurate or is this actually normal for Danial defense? This gun shoots almost everything sub MOA the .36 groups were with fiochi 55g psp witch is definitely not even a mach round. Thanks for your input.

luck of the draw. come barrels will shoot better than others

You have heard wrong...

DD has made its name on being a tough accurate rifle that only incorporates what is needed...no frills... just an extremely dependable hammer. My experience is that Daniel Defense makes a superior barrel compared to majority of factory AR15 barrels. All of mine will shoot 1/2" or better. It is as good or better than my Noveske barrels. The only step above this is a full on custom barrel.

Your barrel just sounds like another typical DD barrel.... nothing special for DD, but huge for everyone else! You got lucky in that there is a DD barrel in your rifle... you will not be disappointed.

Did you obtain any groups that weren't 0.36 MOA?

Rex,

Yes, it's a statistical aberration.

It's all about statistical averages. You will not be getting an average of 0.36MOA in an AR, with a DD barrel and PSP bullets. 0.36MOA assumes a Normal curve, so some groups will be even tighter, and some groups will be wider than 0.36. Plus, not discounting a single bullet - being honest and including all the 'fliers'. If however, every group with that combination is on average 0.36 then you need to contact DD because they will buy it back off you for a handsome price so they can frame it on the wall in their Head Office.

My limited experience of DD barrels is a 14.5" pencil barrel shooting 1.14MOA on average; 8 x four-round groups from the bench with a NF scope - factory Aussie Outback ammo which uses 55gn Sierra Blitz Kings. Best group was 0.5MOA and worst group was 1.7MOA.

Sorry - I went Big with my statement. 0.36" is an exceptional group and not going to be typical for factory ammo. As Klem pointed out, you should not expect the same results when using factory ammo. I have been shooting Daniel Defense rifles for +10 years for plinking, hunting, and 3-Gun. By dumb luck it was my first AR15 and since has become the only off-the-rack AR15 that I buy. I have been impressed with their barrels, and as a result it is my first choice of barrels for a standard quality build. My experience is that their barrels are reliable/consistent, accurate and well made. My generic bulk reload using 55gr Hornady FMJ (bulk box) with TAC or H335, and range brass is 1/2" - 3/4" in all of my DD's. I used their barrel in my 300BO build and it delivers. For what it is worth, I am not a fan of pencil barrels on AR15's. They aren't rigid enough for hanging a suppressor (too much POI shift) and heat up too fast.

I had a guest pick up a cartridge off the ground and load it into the magazine (he should have known better and I didn't see it happen). Next thing I know he detonated one of my DD rifles by firing a 300BO through a 5.56. Fortunately, no one was injured. The gun broke where it was designed to fail. The gun was toast... the barrel was pristine... no noticeable bulge or swell. Felt weird throwing it out, but safety first. I was sold... and Larry Vickers torture tests episodes confirmed/solidified my impression of a Daniel Defense rifle. Best Ugliest Hammer right off the shelf.

DD is top shelf

Yes, it's a statistical aberration.

As Klem stated, many post groups from their guns that are great but are not statistically accurate.
Klem wrote years ago, (not a direct quote but the same meaning), that a group could be shot that prints 5 through one ragged hole. However, that same barrel may never do that again. Ever! It was an anomaly.
And in the great grand plan of the cosmos, a BCA barrel has a chance of being an exceptional shooter. Hell, I even have a chance of being a great shooter! Every dog has his day. But if Vegas were to do the odds, well, not so great a chance.

Thanks for the info guys and yes the .36 moa group with that ammo is repeatable. I get around .70 groups with Hornady frontier and .65 with Hornady eld match. I will do some more grouping at some point to see how other ammo performs. The thing that was getting me was that it seems like I need to spend a lot more money on a 6.5 G barrel to obtain the same level of accuracy ?

Really? So you are saying with that rack barrel and cheap ammo in an AR you are getting on average 0.36MOA? That is unbelievable.

What's your setup? How many rounds are we talking about? How many bullets per group? Any photos?

[Rex colt]

I have only a few photos I will post them and will continue to test new ammo and keep updates. The setup is palmetto lower with palmetto lower parts kit Magpul MOE furniture, standard aero upper that's been lapped and locktighted, BCM bolt and carrier, Daniel defense 1 in 7 lightweight cold hammer forged chrome lined barrel, ( mid length ) palmetto low profile adjustable gas block, A2 flash hider and Midwest industries free float gunfighter rail. They are 4 shot groups I have shot 2 to 3 groups with each ammo and it seems to almost prefer 55g to the heaver stuff I have more ammo on the way for testing I will update when I get it.

How do I post pictures ? new to the sight

And I forget the sight is a PA 1 to 8 ACSS

This is the interwebs. You can shoot a group at 25 yards and say it's 200.

Rex,

So, you have fired two to three groups, which is eight to twelve rounds of factory 55PSP with a $400 scope, MILSPEC trigger and rack barrel.

One thing is for sure, before buying a lottery ticket you need to shoot a lot more rounds through that gun to say with any confidence what the average group size is.
