4.00" OAL extended magazine. DIY?
I have a .338 RUM that I would like to put an longer mag in, but dont feel like paying $200 for a gun smith to install it, when the guys in these parts will probably just use a dremel anyways.
So my question is, has anybody done this themselves? I know that I would also have to machine the bolt stop down. Can I do it with a dremel (im pretty good with power tools.)?
