I see ads all over for night vision scopes, cameras etc. including the Sightmark Wraith for around $600. any others out there, reasonable price for less that 100 yard shots?
The less costly units are going to be some sort of adaptation of a “camera” onto your existing day optics.
Note : the sightmark / ATN products feature their own built on mount to adapt to the firearm / this will always yield the optimal repeatability necessary for 100 yard engagements.
IF you’re a risk taker and like to tinker (with your zero) then YES there are less expensive options.
Note, anything you adapt to the back of your scope you’ll need to take into account eye relief, the unit below is going to give you night time capabilities at the expense of your daytime position of the day scope (it’ll need to be placed far forward on the top rail of the rifle).
This is cheaper than a wraith but as you’ll see has many technical challenges !
