Fixed: 18" Alexander Arms barrel: 2.5+ MOA

I cannot emphasize how easily the barrel came out of the extension.

Barrels can not rotate in the barrel extension after they are assembled. Once they are installed they are pinned to the barrel.



They cant rotate without shearing the steel pin. If your barrel rotated in the extension then it was not assembled correctly by the barrel manufacturer. The pin was probably not pressed in properly or the barrel was not drilled deep enough for the pin. Can you post a pic of the barrel extension and pin? It would be interesting to see how far the pin is protruding from the barrel extension compared to the pic above.

However, he did reply that the barrel should be torqued to 120 lb ft into the extension and to use green loctite

I cant believe Alexander Arms would give you this advice. It needs to be headspaced, timed and pinned.
