BSA R-10 Dust Plug - Standard
This is a brass or black delrin dust plug to keep dirt and debris out of your BSA R-10 fill port while you are out and about.
It has a port to allow it to vent off any air should there be a leak from your fill port on your rifle.
This model may not work if you have a tilt & swivel bipod like the Harris because it covers the fill port.
I do sell a flush fitting model, please look in the eShop.
These will also fit the HW100 fill port.
