strike industries megafin in a KWA m4, fit?
 

Guys, I have a KWA RM4A1 (my first airsoft gun) and would like to know if this rail system, in this size, would fit in it:

I'm a bit afraid to buy a rail longer than the actual barrel or that wouldn't hold with the stock outer barrel format.

I don't think that rail system would fit but I am not 100%. The barrel nut is standard aeg threading so most standard keymods will work. Airsoft depot has a bunch of keymods that will fit if that's what your looking for. I just installed the 16.2" wirecutter on my km4 from there and they had a bunch of different lengths of regular keymods

well, it turned out it worked like a charm. extremely easy to install, no movement like any good free floating, very low profile, love it. I'll post some pictures this weekend for those curious about it.

I have the same one. Very easy to grip to the small hex diameter.

The finish to grippy , edges are sharp and feel a little abrasive on bare hands. Other than that, it is super light and strong.
