Dan_uk86 Posted March 28, 2011 Share Posted March 28, 2011 I have been looking round for some cheap m4's and i came across one that does not fire and the gears are seized. this is going for 80 pound and i was wanting to know how easy would it be to fix? or would getting a better gearbox be the best option?

kejot Posted March 28, 2011 Share Posted March 28, 2011 id want a working gun for £80, by time you strip it, get the replacements parts, bevel gear, motor pinion and poss anti reverse latch at least youve added another £20odd, but you can get a element v2 box for about £45+ Link to comment Share on other sites More sharing options...
Dan_uk86 Posted March 28, 2011 Author Share Posted March 28, 2011 I already seen the vid to unjamming the gears. but for 80 pound im still unsure. i wouldnt mind getting it and having a go at fixing it myself. but realisticly if its a big job that may in the end require more money i may aswell save up and get a full working one with out battery seeing as it will be cheaper and i have one i can use being delivered.

Dan_uk86 Posted April 5, 2011 Author Share Posted April 5, 2011 I managed to get it reduced to just £68! i have had the thing open and had a good look at all the parts ( 8 hours+!!) for my first time id say ive learnt alot i have had the gears aligned and firing but they lock up soon after. i dont have enough shims to better adjust the gears or bushings or any grease to place on the gears.
