**WARNING** When you get your stock and start to assemble it, DO NOT, and I can't stress this enough, force anything. If it's tight, find out why and FIX it. The Dremel is your best friend. Do not force any screws either. You will strip the inserts. If you don't like how the mags load, contact us, we have a fix for that also. It's called the G5 mag adapter. Sorry if this sounds like a sales pitch guys, but we do have a fix for the mags and the clearance issue behind the pistol grip.
