    Default JTK Barrel conversion

    Hey JTK

    Hows it going with the .20 conversion on your s410 ERB?
    Any news from your side?
    I got a mag yesterday? My rifle should be ready by the weekend for testing.
    Also got the AA TX200 Silencer.

    The only downside so far is you wont be able to load heavy pellets (24grains) in the magazine.

    .20 24grn (actually 23.2grn) Eunjin's will fit perfectly into the .22 S410 MAG I sent you JTK. Tested it myself.

    The S410 Mag is 10mm deep and .20 EJ's are 10mm long so the fit is exact. If you experience a few too many sticking on the turn just remove the front plate on the Mag and space it a fraction with a washer.

    Fox I have to admit, what a brilliant idea. The only problem on my rifle is the gap where the mag slides in. Thats very tight and no room for a washer on the yellow plastic. Please advise?

    Take the mag out and sand it down by lying sandpaper on a flat surface like a kitchen counter, and moving the magazine in circular motions over it.

    Not sure about that, the mag I had was only for R&D purposes and I don't have an S410 rifle. Nevertheless, we are only talking a fraction of a mm here. I doubt whether a spacer will be necessary. Just mentioned it due the inconsistence sometimes experienced with EJ pellets.

    All this talk of s410 's is influencing my decision on whether to buy or not to buy!! AAAARRGGG!! The S410 I have my eye on is the older model and it does not have the adjustable power lever but I'm sure all the same things will apply to the .20 mods
