My Temperament:

Airsoft Replicas Owned

  1. So I'm a reasonably experienced tech, there really aren't any guns I haven't been able to fix. Enter the echo 1 platinum edition m4, owned by one of my friends on my airsoft team, which he absolutely loves and adores. My friend comes to me saying there's an fps/range problem (normal fps is 370-400). I open up the gun, and the gearbox is literally the most pristine stock gearbox I have ever seen (auto shim, o-ring nozzle, good grease, great compression, etc.). I take a look at the hop up, and no problems there either. so this leaves me basically stumped. I put everything back together and fire a few rounds, chrono it (shooting INCREDIBLY low, around 280 or so,) and then the piston strips. One thing I did notice was that the gun sounded kinda like it was halfway to being jammed. So we get a new piston (http://www.evike.com/products/38172/) and the seal is still great, and I check the nozzle's seal with the bucking, everything is all good. Shoot it, chronos 280. Clean the barrel, 300. Different bucking, 300. Shave the tappet plate, 300. New madbull 6.03 tightbore barrel, 300. Different gearbox shell, 300. New hop up, 300. Same gearbox shell, 300. Old barrel with new hop up, 300. At this point I've ruled out pretty much everything that could be gearbox related, so I focus more on the hop up/ barrel, and find everything to be in order. So now I'm completely stumped. My friend is about to order a prowin, and if I can't figure it out by then, he's probably gonna get a new gun. Any ideas or suggestions?
