Re: PEQ-15
CoryT is correct reguarding the regulations.
I can tell you the PEQ-15s you see on ebay, gunbroker, arf, or where ever are 99% likely stolen. If you have seen what they sell for (~$3000) you can understand why people steel them. It really infuriates me. I just shat on some supply theifs post a few weeks ago on ARF for listing a stolen PEQ-15. I don't know if he still sold it or not.
