Hello, everyone. Have played airsoft for 4 moths now. Played with rental guns on a good site so have got some experience but not much. Have got my UKARA and now in a stage of gearing up slowly. Few weeks ago bought a second hand G&G l85 carbine, researched about it and it looked like a good deal, it looks ok. But the shooting from it in first place did not impress me much. I have got 260 fps out of it on .2bb... when people say they`ve got about 330 out of box....grrr ok, but the range was not great either. OK, said I, lets look what can I do with it) First cleaned the inner barrel out, which did help with range but not as much as I wanted. Next step was changing the spring to increase fps a little bit, bought a PDI 120% spring for AEG, when it came in it was shorter then the one which was fitted before.... ok... maybe I am not so top tech yet, so installed it to check what happens. The fps gone to 280 on 0.2bb. To be honest I was expecting much more. In same time the Lonex metal hop up unit with flat hop arrived, installed them, apparently it is good mod for range. Yes, the range did increase but still does not go further then 20-25m as I can see, in a game it is impossible to compete to another m4 and g36.... Also changed a air nozzle as old had some wear on the end. I am using the 0.25bbs as they still more accurate than the 0.2. Did the check of the cylinder and stuff when I compress piston and hold nozzle with finger in looks gas tight. The carbine inner barrel is not so long and I am thinking if there are any chances to buy outer barrel from ics L86 and fit into it or just get standart L85A2 outer barrel as it has got 510mm inner barrel comparing to my 407mm. As longer inner barrel is better for range as well, isn`t? Any suggestions what to do to increase fps and range a bit more, please? Also about the spring lengths, is there any standart for some gearboxes or it is all about metal and wire thickness? Thank you,
