Just finished my build the other day. Like the OP - my blood, sweat, and tears went into this build. Everything that could go wrong, did go wrong - lol.
Worth it though. Learned a lot along the way.
This version has the JP Rifles hand guard. It's front wired with a 1500Mah 70c 7.4v in the PEQ. Considering getting a longer outer barrel and reversing the silencer like previously suggested in the thread. With this, I could fit quite a large nunchuk battery in there I figure
Oh and I'm totally aware there's no front site on it yet.
