Night Vision Insight (mtm) wtm and pi as clipon

[Cshultzy999]

I’ve been seeing a couple of the tan model (wtm) and (mtm)-pi for sale recently at a decent price and I was wondering if anyone had any hands on experience clipon mounting either model. I know the earlier 320 models weren’t built for the recoil and lacked the collimation for clip-on but I’m interested in knowing if the tan (wtm) and pi models would make for a pretty usable clipon.

The Tan MTM is not a WTM and is not rated for weapon shock. The 17 micron systems are weapon shock rated. If you do use the early non-WTM (25 micron system) on a weapon you stand a very real possibility of frying the FPA. L3Harris has zero 25 micron FPAs left to repair the unit. THE MTM and WTM where never designed as Clip ons. You can use them as such but you will need to zero your day optic behind them, defeating the purpose of a Clip on.

Also there are only about 4 Tan MTM's that were not sold to the US Government through ADS, chances are very high that the unit is Government owned.
