Way back when I bought a FAL kit and Imbel receiver and thought I'd built up my knowledge to where I could build one. But in '06 I got sick pretty bad and it pretty much erased my memory and now I can't tell one part from another. Now boredome has got me assembling all the tools I bought for this and while I can't find them all I found enough to do the job I think. Here I've removed the old receiver stub (that was fun) and installed the barrel. More fun there as I had to file a 1 1/16" wrench to fit the barrel and then file the barrel shoulder so it'd time right. Whew! taser1 Now I'm putting in a .264 locking shoulder, and I had to drive this thing in. I maean DRIVE it in! The side with the tab still barely sticks up above the hole - does this have to be flush? Thanks for some help!
