I've just ordered fiber optic sights for my new 10/22 and was thinking about one for the front of my PLR. I replaced the rear sight with a peep sight from the SU's and painted the front post fluorescent green, these have improved the performance greatly. Maybe a fiber optic post would help even more in lower light situations. I know a red-dot would be cool but, i want the lightest weight, most reliable (no batteries) gun I can get. Ive seen some AR-15 fiber optic posts (Tapco AR0902 AR15/M16/A2 5-Piece, Color Front Sight), can these or something similar be used on the PLR?
