    I have a couple Lmt Mws’s and a handful of barrels. A few are converted Noveske’s which are armalite pattern and the others are factory Lmt. I run the armalite bolt in the Lmt carrier with the Noveske barrels. Same .068” dia firing pin, protrusion, etc.

    As best I can tell the Armalite bolt has about a .004” deeper bolt face than the Lmt bolt. Lug length, width, OD, etc all seem to be the same. Is there any reason I can’t have my Noveske barrels reamed to headspace with the Lmt bolt? This is partly for the sake of simplicity, not having to swap bolts, and because I prefer the dual ejector Lmt bolt. They’ve been more reliable and are much easier on brass vs single ejector versions(virtually no ejector swipes).
