AR-10 Build (DPMS Gen 1 pattern)

[Ehunt]

Had a bit of a SNAFU during a Barrel installation. My barrel nut was too deep and was not getting to torque before the nut started touching the receiver. I am getting a new barrel nut from the manufacturer, but during the installation the barrel was loose to the point that the I didn't notice that the Barrel Extension had moved out of the 12 o'clock position and the pin was no longer in the Receiver Notch. Thought all was good and began torquing down the barrel nut. I noticed what was happening and stopped, but not before the Barrel Extension Clocking Pin had tried to make a new notch in the receiver. Fortunately the threads are fine, and other than the depressed point where the pin tried to make a new notch, there seems to be no damage to either parts. My question is this, could this affect re-installation or accuracy? I am not thinking so, but wanted to know if I was wrong or if y'all have had this problem before also. - Thanks

Had a similar problem on my LR-308 build but it was all on me! Dropped the receiver and dented a spot on the lip of the threads. Took a needle file to straighten out the threads, applied BLUE Loctite to the barrel extension and installed as usual. I've probably run a couple thousand rounds through it since and have had no problems at all. Extremely accurate rifle and the Loctite fills all the voids ensuring 100% contact between the receiver and the barrel (just be careful to not get any on the barrel nut threads or inside the action). I use the same procedure on all my 10/22 builds because the factory barrel to receiver fit is fairly sloppy.
