Just the AN/PVS-14 Gen III Pinnacle will set you back $4k. Add an Aimpoint ($500), BUIS ($300), and front grip ($50) will get you real close to your $5k figure.
And that doesn’t even include the rifle! (another $1k-$1.5k depending on options)
Damn, what BUIS are you talking about that’s $300? I think top of the line LaRues are half that.
One each YMH Smooth upper: 16”, BUI, birdcage...
Oly lower, self assembled, RRA two stage trigger.
CCA telestock, open to replace...
Comp M3: 4 MOA.
Expected use is targets under 200 yards, with in truck support a major requirement.
Does what I need it to do, so why ask for more?
... although, there was that low light camera/thermal imaging sight system I did a few years back...
