Hey, I'm looking to "overhaul" my M4 (M15A4, if you're going by Classic Army terms). I want to change the retractable stock to a crane stock, rewire it, and change the front hand guard to RIS or RAS. I know the crane stock can added and the battery rewired, but I don't know if you can convert the front end. So my questions are:
1) Can the front be converted from the two plastic halves which currently house the battery to RIS or RAS?
2) If so, what "kit" do you recommend? What retailers sell it?
3) What crane stock do you recommend? What retailers sell it?
4) I know a lot of you can rewire it, but I'm trying to figure out how the AEG works so I can do some upgrades myself and start understanding the general mechanics of the thing so I'd like to try to do the upgrade on my own. Is there a trick to rewiring?
Thanks.
