Re: Keltec Sub 2000 9mm??
They're good little carbines, my dad has one. It's an early one with the metal receiver (which is apparently worth a decent amount of change now)
It is a little uncomfortable to shoot because the recoil tube IS the cheek weld are so the vibration gets to be annoying. We fixed it with piece of foam pipe insulation.
Get it with the Glock mags and find some 33 round 9mm mags and you have a really portable little rifle. It's easily accurate out to 100y with no issues.
He has a Hi Point carbine as well that he setup for can use since he didn't want to "bubbasmith" the rare Sub2k. Between the two, the Keltec is a far superior weapon in fit, finish, and out of the box accuracy.
