The two best civilian power lasers on the market at present are the DesignateIR-V and MAWL-C. The IRV is about $2k, the MAWL about $3600.
The civilian PEQ is a dog. The full power PEQ has a great laser, but the MAWL-C and DIR-V come very close due to the tech they employ. And both have better IR illumination than both PEQ options.
The DBAL-D2 is toaster size and seriously lacking compared to the MAWL-C and DIR-V. It clown shoes large, seriously.
I’d skip all the other laser options including the full power grey market stuff and go with DIR-V or MAWL-C. Both have great laser power and IR illumination.
The DIR-V is really small, lightweight, and has a great user interface.
As for the rifle, you have three nice options. I’d choose a longer handguard over a shorter handguard. And choose whichever has the least handguard deflection when loading the handguard.
My primary nvg gun has a 12.5” BRT barrel, 10” mk16 handguard, capped nx8 1-8 in 1.97 NF ultramount, and DIR-V. It had a MAWL-C on it until this week.
