All rite, a second try. Thanks to all you guys comments I changed up the weapon a bit...well quite alot from the first pass of textures. Any further C&C is lovely welcome! Thanks for watching.
I'm not sure why you moved the center point of the barrel all way up to the front? Pull that back down the barrel no amount of texture tricks normal map or otherwise are going to give the illusion of depth, more then actual depth. If you're set on leaving it the way it is, then remove the extra loop. It seems really low…
