Accuracy fixed.

[Klem]

Klem, there is no issue with a little loctite on the face of the receiver. The point of lapping and loctiting is to facilitate a "single piece of metal" barrel thru receiver. If there is a little loctite on the face ( after cleaning off the excess), when the barrel nut is torqued down, it just helps to insure that there is no slack anywhere between the barrel and receiver. If there is any space or gap anywhere in this transitional area, there is opportunity for movement at ignition which creates an upredictable shot to shot variation. Just remember that if a little loctite is a good thing, a lot of it isn't!

Thanks for replying but I remain unconvinced that glue between the receiver face and barrel extension increases accuracy. If you go to the effort of shaving minute angles of metal off the receiver face to square it why then let glue or any other substance in between that carefully machined interface? If there is slop between the extension and receiver then by all means try and fill it with something that hardens (and does not flow when heated). But the receiver face and the extension journal needs to be intimate.

I am aware quite a few people don't care about the excess glue squeezing onto the shoulder but I imagine your guns would be even more accurate if you could somehow get the glue to where it is needed, and keep it from where it is not.
