View Full Version : 80% take down pocket too tight.

Apparently it is fairly common when machining a 80% lower to find that the lower and upper won’t mesh properly due to the square lug of the upper not have proper clearance at the corner of that lug. Can anyone suggest the best way to address this problem. I believe that it is a small, perhaps 4 thousands too tight but I don’t think making a whole pass is needed, just at the corner. One of my friends just put a file to the lug corner. Thoughts?
