Re: 21" Noveske barrel for an AR-10(Yes Armalite)
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: bignada</div><div class="ubbcode-body">DPMS and Armalite AR-10 bolts are interchangeable. Difference is in the carriers. Armalite uses the bolt rebound spring, DPMS does not. DPMS carrier has about .010" more steel between bolt face and rebound, thus no spring needed.
Noveske has always built on the Armalite platform. If they are doing DPMS now, it is a recent development.
Possible to run the DPMS bolt carrier group in the Armalite receiver; have done it. Understand the DPMS extension has different thread pattern than Armalite.
Noveske is Pac-Nor unless that too has recently changed. Nice gear. If spending the money, why not ask George Gardner GA Precision about a 10 barrel and matched bolt. If you really want The Best... </div></div>
While a lot of the work is done at Pac Nor according to John they are not exactly the same. He buys his own barstock and the tooling they use is his and the barrels are "finished" at his shop, whatever that means. I don't know if it is still up but there was a good article in defensereview about it.
