Rewire

Posts Tagged ‘Rewire’

Still Airsoft never goes away even if real life is a bit busy on occasion.

Recently started a rebuild of my SRC M4 including a paint job. Now I’ve never done a rewire so it’s a bit of a learning curve and chuck in the addition of a Gate Nano AAB mosfet


then things get interesting. Especially for a non electrical type like me.

Started by taking lots and lots of pictures of the current wiring as I stripped it down to ensure I could put it all  back if need be. A word or two on the strip down – bloody awful. The SRC is a very badly designed V2 piece of kit. Shame as it runs great but the take down is complicated. Gear box internals are as standard however which is good news.

This is the first time the box has been opened on my SRC and from the get go everything was clearly coated in shed loads of an unknown grease. First job – a clean down with electrical contact cleaner and a relube with a good quality synthetic grease containing PTFE. The PTFE aids in preventing what is known as stick slip in lubrication parlance. At the point of start up there is always a high level of friction between metal surfaces when they’ve been at rest. The solid PTFE keeps the surfaces separated and aids immediate start up. Not sure how much it adds to performance but the theory is sound.

Decided to upgrade the spring at the same time and have a go at porting the piston to see what happens. It’s always been slightly underpowered so this should help.

Cosmetically I’ve added a FAB defence mag well grip. Had it for ages so it’s fashionably uncool in a magpul world but I don’t care as its comfy.


So the rewire…. Turns out that the twin core I normally use for such jobs is a tad too thick for the job. It caused a jam up between the hop unit and the upper receiver putting a twist on the hop onto barrel connection. Not good.  Hmm. Still don’t like electrics. So the rebuild is on hold until the narrower gauge bendy silicone wire gets here from flea bay. Also took the opportunity to order a replacement mag catch and a CNC hop unit. In for a penny I for just over a few quid in this case. Money well spent. Stay tuned.
