Hey guys, looking to see what kind of interest there is for this. I have a G&P m16a3 with a 14" outer, 12" Daniel Defence Rail, And Crane Stock. There is an issue with the gearbox, but not entirely sure what it is. From the sound it makes, it's something with the gears or pistons. It makes a sound as if the gears are turning, but maybe not catching correctly? Shouldn't be to much of an issue, just don't have the time or expertise. The gun itself is around 300 new. The Rail and other parts puts on it, plus the original furniture and barrel puts would be about 150-200. A new gearbox specifically from g&p would be 70ish. So I'd value around 300 for it. Would definitely move on it, it's just a suggestion. I would trade for a 416 either g&g, elite force, etc. hmu and we can talk thanks
