So I've been out of the game for quite some time now! I've been getting the bug again to build an M4 gbb what is everyone using these days as a good base for a GBBR?
I used to use WE M4 platform as there were lots of parts available and direct replica when it came to real parts for rails and such but I'm curious if something newer has been unveiled?
Thanks everyone and BTW awesome looking M4's!
