View Full Version : First build, next problem

June 29, 2007, 19:05
Using a DSA G1 receiver and Imbel barrel. Had to chase the threads on the barrel with a 1X16 die to clean up the threads enough to screw into the receiver. Threads cleaned up nice and tight but barrel now overtimed to 1:00 position. Any suggestions? I'm kind of stuck. Thanks.

Sounds like you might need some Breeching washers to get it to time correctly just like they use on the inch style l1a1 versions..........

The concept is sound, and the correct cure for your problem, but an Inch breeching washer is going to be much too thick to serve your purposes. Use a set of feeler gauges to determine approximately which thickness will bring you into proper hand-time territory, then make your own breeching "washer" out of appropriately-thick shim stock.

The cleaning up of your barrel threads and the overtiming are two separate issues; one is not responsible for the other. Perhaps some previous barrel owner relieved the shoulder for a former build.

Gun Things has special very thin breeching washers that will make up a few thousands of space. Or you can do what I did and buy shim stock 1" id washers and trim the outside diameter to the proper diameter. I wish I had found out about the pre made ones. Or you can do what DSA recommends and lathe turn the barrel to allow the use of a L1A1 breeching washer.

One of these folks should have what you need.
Think it would be a .010 or .011 washer, but I could be nutz! :p

Gunthings is a FAL Files vendor. The other "guy" has abandoned the board although his forum is still up for a little while longer. I know where I would spend MY money.
