Hi guys. Has anyone used JB weld to build a "shim" on the rear bolt baffle to improve primary extraction? My idea is to build up the jb weld on the front of the baffle, the side closest to the receiver and them sanding it down until i get maximum primary extraction. Can anyone see any downside to doing this? Or any durability issues? This is my training/operating rifle so it sees quite a bit of abuse.
Yeah. Bonding epoxy to metal is difficult under the best of circumstances. Using a cheap epoxy like J.B. Weld further reduces your chances of success.Quote:

Adjust them in and out to get the extraction you're looking for, being sure the parts are not skewed. Then use a drop of Locktite and you're good to go.
You can also use an end mill in a vertical mill to cut it off of the end of the bolt
Nifty idea, I wish I would have thought of it!:pQuote:
