I'm weeks if not months away from doing anything with the rails, waiting till I get the performance right. I like the tinkering aspect of Airsotf as much as playing.
What sort of tools would I need?
I've already been busy doing loads to the internals.
I've completely stripped the Tippmann and put it back together again a few times, it's a lot easier than an AEG.
It's had 2 inner barrels and 2 different buckings, flat hopped, since I bought it. Also serviced it, greased O rings internally, removed the piston to convert to semi only, change the ROF setting, re-did the TDC mod, greased the buffer spring, taken off the buffer tube etc. Next on the list is the dwell mod.
To do all the above, in terms of specialist tools, just needed the barrel/buffer tube spanner that came with the gun and various hex keys, mainly imperial ones as Tippmann uses imperial rather than metric.
Cheers
