    First off...for those of you new to Airsoft Society.

    Let me say this first off. American Consumerism Does NOT apply in Airsoft.

    This thread has been create to help those of you suffering with the "odd" tolerance issues with EF G17 in Gen 3 and Gen 4

    Here are some videos of them working - AFTER Hand Fitting:







    Slide was binding on outer barrel with this unit. I "Hand fitted" this unit and now it's working.



    This is the comment from another user:

    There's another company called gas blowback central that makes a threaded outer barrelnfot ef gen 4 glock 17s but only issue is that it has the same design problem as the pro arms. I like the ef glocks, only downside is the little support it has. But I am looking forward to the ghk glock 17 gen 3 since they're working with umarex so its also a liscensed product and will definitely have more support than the elite force glocks.



    My comment
    Geez...thanks Umarex/Elite Force....

    da_469169 says:

    Yeah mine has that nub.

    My comment
    Wow...are tolerances that varying from unit to unit? You have the Anti-cant nub too on that Gen 3?

    da_469169 says:

    Another thing I wanted to add, is that the tm barrel that I also bought works fine with the stock hop up for the gen 3, didnt have to sand down the nub however it is a little more stiffer if I use the maple leaf hop up. I bought my glocks this year.

    treefel issues with his Gen4 - Notes for all.

    So, I took your upper and put it on my lower and it works...flawlessly.

    I take my upper and put it on your lower and it binds.

    So that means the issue is in the tolerance of the lower.

    I ended up hand fitting the slide with PA barrel to your lower to get it to work.

    Issues were:

    The tongue on the outer barrel was too tall for your lower.
    You anti-tip plate was thicker, so I filed a shallow channel and it no longer rubs. You will see blue sharpie on the inside.

    The front rail was bound down tighter than my model.

    The centering collar on the PA barrel was honed out. Stock barrel doesn't have a centering collar...it used the orange tip for that.

    The outer barrel anti-tip space was enlarged.

    So...now it works.

    christm-43 from ebay had a stock slide that gouged his stock outer barrel and prevented use with PA outer barrel.

    He ordered a new stock slide and now the PA barrel works.

    Old Slide caused outer barrel rub damage.

    Another case of the tolerances being really bad in this line of Glocks.

    Yeah I didn’t think I’d have such an issue with this gun. I didn’t expect the new OEM slide to work any better since the main reason I got it was because my last one was just really damaged. Thankfully it fixed the issue for me and works decently now.

    How is Vega able to make some nice rifles and pistols, and then this happens? Christmas rush? All guns are made on Friday?

    I didn't see the first order, but it was 10,000 pieces I heard...when you normally batch out 1200 pieces per run (large run too)...you can throw out QC with 10,000 pieces.

    And ironic...VFC contacted me to get Birchwood Casey Aluma Black because his supplier did not have what he needed.

    BTW...that wasn't Vega chatting at me and sending me hearts...that was the sales manager and it's a lady.


    I sent him 4 quarts of the solution...guess he has what he needs to touch up a LOT of Glocks.

    Wow you got lucky. Go get a lottery ticket, quick.

    Ace Tech unit is 14mm-. Pro-Arm units are 14mm+

    You will need an adapter or switch the thread adapter to a 12mm+ to 14mm-

    ppra1742

    No everything works fine I’m happy with the Barrel...... hey quick question the barrel that you sold me doesn’t fit the Acetech Lighter R what thread adapter should I use? If you know please

    Fit is one thing, it always fit. Operation is another issue if the lower grip is out of original tolerance.

    Gen 3 Variants, use TM Spec Outer Barrel
    Gen 4 Variant, use EF GEn 4 barrel.

    These are all for EF Glocks. Albeit with potential hand fitting required.
