Hey guys,

Got a stripped AR lower laying around and wondering what to do with it. I was thinking about doing up an M16A4 type build with 20" barrel.

Is it worth it to spring for a Krieger 1/7.7 over say a BCM 1/7 Govt profile?
 
Re: Krieger barreled upper or BCM 1/7 for precision?

A barrel is only one part of the formula for accuracy.
Krieger does make nice barrels.
 
Re: Krieger barreled upper or BCM 1/7 for precision?

IMO, you'll get better accuracy from a Wylde chamber than from the 5.56 that comes with the BCM. Have you looked at the 20" DMR barrel from WOA? Can't go wrong with Krieger if you can afford it though.

Can you elaborate more on the Wylde chamber vs. a standard 5.56 chambering?
 
Re: Krieger barreled upper or BCM 1/7 for precision?

Definition stolen from Wilson Combat:

.223 Wylde is a hybrid .223/5.56 chamber designed by Bill Wylde to yield the accuracy advantages of the match .223 Remington commercial chambering but without pressure or reliability failures when using high velocity 5.56 NATO spec ammunition. The .223 Wylde achieves better accuracy by having a chamber throat that is tighter than 5.56 but will still function reliably with military 5.56 ammunition as the case dimensions are the same.
 
Re: Krieger barreled upper or BCM 1/7 for precision?

Krieger's website is horrible. I don't think they do govt. profile barrels for AR's, at least that I can find on their website.

I think their DCM would be pretty front-heavy on a 20". White Oak barrels look pretty beastly too.

I just basically want an M16A4 that I can squeeze more accuracy from by adding a good trigger and barrel.

I'll be hand loading for it, so that Wylde chamber would be nice but it sounds like a lot of $ to get a Krieger the way I want it so I may just have to settle for BCM.

Call Compass Lake Engineering. They will make what you want out of a Krieger blank and headspace it for what bullet you specify.
 
Re: Krieger barreled upper or BCM 1/7 for precision?

Krieger doesn't make Gov't profiled barrels IIRC but they do make some AR barrels and they're expensive as hell. Last i checked around 500$ IIRC. As to BCM's accuracy i feel it's pretty good with SWA 77gr SMK Run N Gun at 2700fps. WOA does make some damn accurate barrels for just as good of a price so thats something to consider as well. I like Krieger a lot but my BCM is shooting Sub-MOA and thats all i ask of it.

Re: Krieger barreled upper or BCM 1/7 for precision?

yeah as long as I can get sub-moa from a BCM that's all I'm asking for right now.

I can always shoot the shit out of out and then get a Krieger down the road.

Why the hell is everything sold out at BCM's site?

I have a 16" rainier ultra match and it is insanely accurate. </div></div>

White oak is the standard for Ar barrels, just walk the line at Camp Perry

What I would buy.

If you want a 20" maybe see if white oak has a stainless HBAR for sub 300. Or RRA I had an RRA NM and it was very accurate.
</div></div>

This is the one that I was going to buy (UM 18") but it was always out of stock so I opted for the WOA SDM 20" 1/7.
I am glad I did as it is lights out accurate.
I can see now Rainier has the same thing in their Ultra Match series except for it is 1/8 ~ I wouldn't mind that one at all either.

That's an option. Does it come with a standard A2 FSB, as I'd like to keep it on there. A2 sights are my favorite irons. How front-heavy is it with a standard A2 stock (if you know)?


Sweet rig!
 
Re: Krieger barreled upper or BCM 1/7 for precision?

I wanted to clarify something I said earlier. I referred to the WOA 20" as the DMR model when it is the SDM one others have mentioned. It weighs 41 oz. just like the Rainier Arms Shilen model.

If you're not concerned about the weight, you can just buy a pre-ban WOA service rifle barrel with the front sight for a lot less. And FYI, the SDM barrel has flats for their 4 screw FSB.

I've never heard anything but good about BCM. It's not just a recent thing that much of what they offer is out of stock though. Some items will pop up and sell out quickly so if you want something specific I'd sign up to get notified and act on it when it's in stock.
 
Re: Krieger barreled upper or BCM 1/7 for precision?

Four years ago I would have said go with the krieger. Today however you have a slew of choices in 1/7 with the wylde chambering. Finding it in stock will be your challenge.
Good luck!

I am almost 100% sure that you can get a stainless HBAR 20" from White Oak with an A2 front sight/gas block.

edit: yes of course you can shoot 55gr out of a 1:7.
 
Re: Krieger barreled upper or BCM 1/7 for precision?

Comparing a Krieger barrel to the BCM 1/7 gov't profile is a bit of an apples and oranges comparison. A better comparison would be between the Krieger and BCM SS410 line. The main difference between the two is that the Kriger has cut rifling and the BCM has pulled rifling (I believe). I got wind that the BCM SS410 barrel is being made by Criterion (unless I'm mistaken, owned by Krieger).

Regardless, they both shoot really well. I've had both and liked both. Is the Krieger worth the extra money? I don't know. I ran a 10X on my AR rigs and didn't see much difference between the two.

If I was running a higher powered scope, it may have made a difference. I don't know.

I will say that the BCM SS410 is a great bang for the buck. Don't let the spec of the 5.56 chamber throw you off. They shoot great.

Yes the SS410 is what i posted above. Sorry about that jello, I know that's not the Gov't profile. The SS410s shoot great, and at 300$ not a bad price either.
