    Default Help with FAL build

    I just bought 4 barrels and 4 DCI receivers. I have tried every barrel on every receiver and each will tighten to about the 9-10 oclock postion. I am unable to get any of them to the 12 oclock postion.

    If I back them each off I get a nice gap between the receiver and barrel face. Any ideas how I can get these mounted correctly??

    There must be a solution. If I use a big washer then I have a large gap in my breech.

    I need advise on this one.

    if they go to far you need to shim the bbl sholder, if they don't go far enough you need to trim the bbl shoulder.

    Sounds like inch barrels and metric receivers.

    Hey here is a site where a guys used an grinding pad put over and up to shoulder of the barrel
    and spins it by hand to take off a little at a time until the barrel clocks to 11 oclock position
    here is the link WECSOG.org - "Texas Jungle" Carbine Build

    You can either trim the barrel shoulder or trim the fwd face of the receiver


    Did I do that?

    Not an uncommon problem.
    Easy way to trim, if you don't have a lathe, but access to full size drill press. Take off the flash suppressor. Put the muzzle in the chuck and center it. Use a slow speed spindle on the pulley system. Using an abrasive disk from a grinding disk with the open spindle hole, grind of small amounts of the facing. Check fit often. If you take off too much, you will need a barrel index bushing. Check with James, the Gun Parts Guy. he usually has them. Gun Parts Guy - Military Surplus Gun Parts FN FAL L1A1
    Good luck on the build!

    First make sure that the barrel is not bottoming out inside the receiver.

    Remove the material from the barrel shoulder VERY slowly. You will be amazed how little it takes to go from 9 O'clock to 12 O'clock. It will only take a couple of thousandths
