I'm not really sure what your question is. You need to type more clearly.
That said, I assume you're looking to purchase something, correct?
Are you a government organization to replace your current fleet of PEQ-2As? The next gen from there is the
PEQ-15 or
DBAL-A2. The upside for having the slaved visible laser is the ability to zero the weapon in the daylight, which you can not do with the IR only units.
If you want IR/illum only then that leaves pretty much only the DBAL-I2. it has the exact same function, power level, and government only restriction, however it's smaller than PEQ-2A.
However, if you ARE NOT government you have severely limited choices to replace a PEQ-2A. If you NEED a dual IR laser/illuminator unit, you're ONLY option is the
DBAL-D2. If you're willing to go with a IR laser and use an external IR illuminator your options open a bit to the ones listed
here including the Class 1 DBAL-I2 (visible/IR lasers, no illuminators), Class 1 OTAL or ITAL (laser only), Class 1 Las/Tac 2 (lower powered pistol laser), Class 1 CQBL-1 (slaved IR and visible lasers), or the Crimson Trace MVF-515 (red and IR lasers, with visible weapon light).
You'll find your options are severely limited being a civilian due to the 1mw IR laser limit set by our government. Doubly so for ir/illuminator combo units; reason being the illuminators in the PEQ-2/-15 or DBAL-I2/A2/A3 are laser based, using diffused lasers upwards of 30mw to create a power illuminator in a small package. This just can not be done with LED based illuminators like the DBAL-D2 which require a large reflector to project a usable beam, hence it's much larger illuminator.
