I have a pulsar fxg50. It’s a thermal attachment. This this works great. I have never used it on a rifle other than looking through it in my back yard. You can attach to a bolt action by attaching it to the bell of the scope or you can attach to an AR15 rail. Only looking to sell, no trades. Call or text with questions. 972-310-1790. I work in Grand Prairie and would need to meet close to there.
