Re: PEQ 2A
While they are legal to have, they are almost sure to be stolen military property. They cannot be sold (by the mfg or dealer) to other than a Mil/LE agency. It's POSSIBLE that hey came from a LE agency that ignored the end user document not to resell. That said, the MFG will not do any repairs or offer any support whatsoever to a non Mil/LE owner.
If you need an IR laser, get one of the civvie legal units from TNVC. Warranty, supported, more than usable for an individual.
