Will this fit on pic rail ?? Expert Answer

Helpful Positive Review Highly recommend it! by Harold, June 4, 2024
I’ve been using the RFX45 on my AR-15 and it’s awesome. The installation was super simple with the included riser, and it holds zero perfectly. The green dot stands out so well, definitely better than red dots! Highly recommend it!
