Update:
Well here she is in her current configuration, I measured and drilled into the feed tray cover to bolt in a rail for the Elcan, it's aligned nearly perfectly with the barrel but I still need to zero it, hence the offset in the third pic:
I did a complete disassembly and re assembly. Due to:
1. Re-wiring job required the majority of the M60 to be taken apart
2. To apply lock-tight to the Airsoft gun as it didn't have any from the factory. By doing this I have eliminated all the unwanted movement in the AEG including the barrel movement, it's solid as a rock!
So let's start off simple, what needs to be adjusted?
1. Set screw for the rear iron sign should be backed off, locktight applied, and tightened:
2. Remove the quick release barrel, set aside. Remove the bipod by unscrewing (counterclockwise) the nut on the end.
Then unscrew the entire pipe attaching it to the receiver. Apply locktight, and tighten it up good. This connection would rotate when the bipod moved. Once back on, reinstall the bipod, apply locktight and tighten the retaining nut. Leave some space so the bipod can move freely left/right as it rotates on the barrel.
3. I had some bad wobble in the trigger group. To correct, I removed it and bent the retaining tab in the receiver up to apply more pressure. There is a pin you depress on the front left of the trigger group, then it will slide out similar to body pins on an M4.
Internals:
Here is the gearbox, the one pictured has a new piston, cylinder, cylinder head, and has been cleaned out/shimmed.
Quick change spring guide:
I removed the old wiring which had a lot of un necessary runs, just a waste of wire and electricity. The rheostat burned up a lot of juice and even when you put the bit in that cancelled it, all your current is running through 2' of more wire than it needs to...
So here is the mosfet and new wiring, mosfet is accessed by removing the barrel.
I have yet to add the new nozzle but it was running beautifully after all this, still need to chrono on the new battery though but it hit 406 FPS @ 16rps on a 9.6v
