    Galil top cover question

    Hi all, I'm new to the forum and have a question, I just got a new to me ohio rapid fire galil and am noticing some play in the top cover (very little really). I was wondering what is an acceptable amount of play in the top cover if any.

    If this is bad I'd like to get it fixed before I start pouring ammo through it given todays prices ofcourse, any point in the right direction is greatly appreciated.

    I can't tell you about whether there should be any play, but my TennGalil build is super tight with no play in it.

    Welcome. Need a further bit of info. This is a CAI rifle or some other? CAI used ORF receivers and some pretty tired South American stuff for many of their builds, most of which were less than OK. How much play do you have as some of them have quite a bit. The cover should be tight on the top of the receiver. If it's rocking side to side, you can put the squeeze on the top cover to get it to tighten up a bit. Is the recoil spring guide tight in the cover? Is the cover tight against the gas tube? Take the recoil guide rod/spring assy out and check the cover fit side to side, front to back. Is the rear of the cover tight in the recess on the back of the receiver? Are the sides of the cover tight against the receiver. If the answer to any of the above questions is NO, then think about replacing. I had a CAI Golani that the top cover was loose and ended up replacing it. It had been stretched and abused too many times in the past. Sometimes, the covers are just tired and need to be tossed for a new one. All of mine are TIGHT!! My

    Brouhaha,

    Welcome to the forum BTW! To answer your question on what is an acceptable amount of play on a Galil topcover. It should be close to none. Here is why. The development of the Galil rifle was loosely taken from the AK-47 design so in a effort to improve accuracy the Israeli engineers moved the rear sight further back on the Galil's topcover opposed to the AK-47 sights which where placed much closer together. The AK's rear sight was fixed on the upper receiver making it a more stable platform. The Galil's rear sight of course is removed when the top cover is taken off for cleaning. If you have a slight play when you move the topcover by hand you will surely have even more play during firing affecting accuracy down range.

    The Galil/Golani/ORF topcovers are notorious for being a S.O.B. to put back together and many new/novice Galil owners will break out hammers, mallets trying to get the damn thing back on. Sometimes this will lead to warping the topcover and giving this type of play you described. Start first by laying your topcover on a flat surface and checking for gaps towards the back of the topcover. If you are good and flat there the next thing I would check is for a worn gastube (yes gastube) My CAI Golani came with a loose topcover and I noticed where the topcover and the gastube meet (channel) there was quite a bit of wear. I bought a new gas tube (with less wear) and my cover was tight again and problem solved! Congrats on your new rifle! Lou

    Any good sources for reasonably priced and good condition top covers?

    try adjusting the top cover first.
    tension is adjusted at the rear bottom of the T/C where the strap it spot welded on.
    you'll need a small hammer and a block of scrap wood.

    if it's loose turn the top cover w/ the back(square hole) sitting on the block so you are facing the inside of the cover.
    tap along the bottom edge w/ the hammer- lightly- a little is a lot.
    check fit.
    if the cover is too tight hold the T/C facing the strap(spot welded piece) or front of cover away from you.
    at the bottom edge below the square/op rod hole lightly tap along the edge- check fit.
    you want the cover to require a slight whack with the heel of your hand to seat.
    if you need a hammer to put the cover on it's too tight- if it drops on it's too loose.
    if it's a PITA it's just right.

    Looking down the barrel, the left rear raises about 1/8" of an inch with the right being against receiver groove... Front sight moved far right to compensate.

    Will adjusting the back strap fix this or do I need to bend it, or just try to source a new top cover?

    I thought about JB welding a metal shim, but I'd really like to fix it correctly.

    Thanks Tennagalil. Plan on sending it your way eventually anyway to raise/fix Century's feed ramp and possibly a chamber bevel if you think it's advisable. But would like to fix the cover on my own if possible.

    unless you're using a 5lb hammer to put the T/C on your rec. needs the bevel cut on the front trunnion.
    you're fixing the T/C when the rec. is the problem.

    with the top cover off look at the left front trunnion.
    just above the ser. # is a square edge behind the ears/slot for the gas tube- that's what is causing the T/C to cant.
    the outside edge of the flat needs to be angled/ground to allow the T/C to fit.

    i use an 80 grit disc on a air grinder and do a 45 deg. angle all the way from the rear of the gas tube ear back.
    at least 1/16-1/8" flat.

    if you look at a pic. of an IMI or CNC rec. you'll see what i'm talking about.
