Great Scope

By Chase S. on Apr 20, 2023
I purchased one of these and put it on a 7mm Rem mag. Works great. Handles the recoil. Very clear. Same quality as some other brand scopes that have a much higher price tag. Liked it so much I got the same one to put on a 6.5 PRC. I will probably get another one some day. I recommend this product.

I have 3 of these nice little Sightron 3-16X42 STAC scopes

By S Peter P. on Apr 04, 2023
I would not have bought #3 if I did not like them
Very good optics
Excellent tracking
Compact but mounts easily on long action receivers.
Reticle great for long range targets
Markings on windage dials are from 1 to 15 MOA, would be better if they went from R 1-7 & L 1-7
Shooting deer & elks in deep dark forests might be
difficult with .08 MOSA hash marks/cross hairs & .25
dot but great for long range targets on nice days.
The little flip up thingy in the power ring is sort of useless.
