HI All I am wondering what the clearance between the front of the bolt locked in the extension and the breach face should be on an ar-15?? Thanks Hoz

I have found if you cut the tenon length to .620" the clearance will be .008-.009"

I chamber all my service rifle barrels to .007, never had a problem
