Not a problem man.
I've got everything on the gun now, except for the mag tube.... and the light obviously.
I ordered a Tacstar extension, but it doesn't fit the M3's... Anyone else, be forewarned. Also, the Tacstar is steel, and adds a shitload of weight anyway.
I just ordered a "Dave's Metal Works" 3-rounder (extends to JUST behind the barrel like in all the pics we're used to seeing) from Midwayusa.com. It's aluminum so much lighter which is good for the inertial recoil guns.
Should be about 3-5 days, and I'll either post pics in this thread, or make a new one. Not new to vBulletin boards, but not sure if the admins want me to make a completely new post for simple pics lol.
Anyway, like I said before, I had to do mods to make the shroud and shell holder fit, but all is professional looking and didn't change the stock config of the gun... much.
