Bolt Carrier Compatibility

[MarkB]

Hi All,

I'd like to ask for some Bolt Carrier info.

My build is a MA-TEN monolithic upper/lower with Lothar Walther barrel/bolt.  I am waiting on an Armalite BCG, but would like to know if there are other bolt carriers that would be compatible to Armalite.

Thanks,

MarkB

Contact Noveske and ask if they can part with one.

nice combo mark, i have a lw barrel on my larue it is sweet

[MarkB]

Thanks for the info.

Here's my build/order so far.  Am I missing anything?

Thanks,

Mark

Sounds good brother Mark,is it ready to shoot?

[Robocop1051]

Do LW barrels come in both LR-308 and AR-10?

Yes, they will build them for either style.

They made me a 20" for an Iron Ridge upper, DPMS style.  What I thought was weird is that it uses an Armalite gas tube. It is a bit longer than a normal rifle gas tube.

[MarkB]

Thanks, hoping I am not missing something.

And, I WISH :)

I think I am still out 4-6 weeks on MA-TEN (getting monolithic nib) and barrel.

Have a few parts in-hand and am getting antsy for the rest.

Here are a few concerns I have in red for clarification...

[survivalshop]

Why wouldn't the lower DPMS parts group be compatible with an Armilite BCG ? Or for that matter Ma-ten.

[MarkB]

yes, rifle length.

I am also curious as to why you say DPMS lower parts kit will not work.

I am getting parts thru Dave (group MA-TEN buy) and this was part of his recommendation.

I built a MA TEN carbine using a Noveske barrel, Armalite BCG, DPMS bolt catch, ATC SR Gold trigger, CAR X heavy buffer and spring, AR 15 colapsing stock, and the rest AR 15 small parts, (selector, springs,detents, etc). I've had no compatability issues. As mentioned above, I'm not aware of compatability issues with DPMS lower parts and the Armalite BCG. Although I seem to recall a member posting about having an interference issue with the hammer clearing the bottom of the Armalite BC, unfortunately I don't recall what hammer he was using, (maybe DPMS?)

[edgecrusher]

the only difference i think i have heard is that the armalite bolt catch is beefier.

The DPMS bolt catch is smaller than the ArmaLite bolt catch and may not have the positive control in front of the bolt itself being that small.

I am not 100% positive on this, but I think DPMS uses a standard M-15 bolt catch on all their rifles.

The DPMS 308's bolt stops are much larger than a std AR 15's. I think the Armalite firing pin is spring loaded & might make a difference in what Hammer you use .

[mrraley]

Thanks for that picture. I see the DPMS is bigger than a standard M15 bolt catch, but similar in design and the ArmaLite is just bigger period.

And yes the ArmaLite firing pin does have a retarding spring on it. But I use a standard hammer spring in my rifle and have had no problem with it.
