AR Bolt Carrier Assembly

Hey all,
I'm in the midst of putting together a precision AR and I'm wondering about bolt carrier assemblies.

I've read that one should avoid a DPMS (which is terrible luck considering I have DPMS upper with bolt carrier assembly) and am looking for suggestions. I'm not even sure what else is out there is terms of bolt carrier assemblies.

Any input would be great.
 
Re: AR Bolt Carrier Assembly

I would and do use LMT full auto BCG, the increased wieght increases lock time and slows the bolt carrier down, combine a Tubb flat wire recoil spring is perfect combo IMHO.
 
Re: AR Bolt Carrier Assembly

If you already have the DPMS use it.

Are going to order a custom barrel? If so many makers offer a headspaced bolt with the barrel.

I think you will be fine with any of the big name companys including DPMS
 
Re: AR Bolt Carrier Assembly

There is nothing wrong with a dpms bcg,ecspecially since you are going to be using it in a precision build where it will very rarely,if at all, see hard use.
 
Re: AR Bolt Carrier Assembly

The folks who have problems with their bolt carrier groups (mainly the bolt) are the ones who put hundreds or couple thousand rounds through their guns in a very short period. Guys going to combat courses and such. For the average shooter you are not going to see these problems.....if worried about it, get a spare bolt.

I especially love the part where they don't stake their carrier keys.

Seriously though, just stake them and they work. Also, COLT, LMT, BCM and CMT (if MPI'd).

Seems like a sound opinion and option. This gun isn't for blasting a few hundred rounds in a couple of hours. It's a nice day at the range kind of gun where talking is happening as often as shooting.

Whether for blasting or not, wouldn't you rather have a better-built BCG that can stand up to hard use anyway? What if you needed to use that weapon for defense? As the old saying goes - <span style="font-style: italic">"better to have it and not need it, than need it and not have it".</span>

At some point, yes, but that sounds more like a justification to buy something simply because it is "better" than because I might someday need it. That's the kind of thinking that leads to the "Nightforce is the best scope for the money" argument (as if in order to get a scope that works, even one that works well, one must spend $1500+ - Yes, I do have a NF on the way).

I will get one, but if the argument is purely theoretical, as in I might one day need a BCG that will stand up to nuclear blast, I'll wait to try and offset the cost of the gun + accessories before I start adding bells and whistles.

I was under the impression that the DPMS BCG was somehow completely inferior. It seems that it is fine unless I want to put 1000 rounds down the tube 4 days a week. I'm looking at perhaps only shooting a couple thousand rounds a year.

Re: AR Bolt Carrier Assembly

I have a Youngs bolt and carrier. Bought it through Black Weapons Armory. I'm having a gas issue with the AR I built and called Youngs Mfg. I believe I talked to Dan, which I think is the owner, and he really helped me out. I told him where I got it and he thought it might not have gotten staked properly. He said to send it to him and he said he would see to it that it was staked properly and take care of shipping both ways. Great customer serice.

Unless they've changed things in the last few months, they DO NOT stake the gas key. If purchased through most online retailers that carry Young's products they will stake it for added security. You can stake if yourself if your worried about it...it's really easy to do.

I have Young National Match carriers in all of my AR's with zero problems.
 
Re: AR Bolt Carrier Assembly

Youngs aren't staked as Onekneedown said. When I sent mine in they said the chromed carriers need to be torqued to a higher rating than standard carriers. I believe they also said they put some sort of sealant between the gas key and the carrier.
 
Re: AR Bolt Carrier Assembly

That is correct on the Young's bcg not being staked, I have 3 and none of them were.That said, if it bothers you it's easy to do yourself.Also I recently got one from Bravo company that also was not staked, but was MPI'd...go figure.

They stated all of their BCG's are staked. Did you call and see if one slipped through?

From their site on the BCG:

"Bolt carrier group (auto version) for your AR15, M16, or M4. Parkerized exterior and chrome lined inside carrier. Machined to USGI specifications. This M16/M4 carrier includes the proper Mil-Spec gas key. Gas key is chrome lined and heat treated per GI specifications. Gas key is secured to carrier via USGI domestic mfg Grade 8 fasteners and properly staked per Mil-Specs. These properly hardened parts insure a strong staking and proper gas system functioning."

I don't own one, but all of my buddies BCM BCG's are staked, along with the ones just recived for a Christmas gift.
