best peq out there

I assume you're looking for a unit for photo shoot / demo use.  To me, the newer PEQ15 replicas are very close to the real deal with regard to IR lasers.

ALL of the PEQ-2s I have seen are different enough in dimensions to be visible in photos.  

The PAQ-4C replica from G&P is spot-on as far as looks, function, and fitment.  It's an older style laser, but there are still units out there using them.  I haven't handled any of the replica IZLID units, or the D-BAL, but they look good.

If you NEED a PEQ2, try Gearbox Airsoft.  I got a good looking replica from them awhile ago that has held up well.

im not sure about gearbox, because i live down here in crapsun, but the main purpose of the peq im looking into is to hold my m249 battery, have a lazer, and be durable all together.

Then the Nitro Vo. PEQ2A box should suit your needs.
