BSA R-10 Dust Plug - Flush Fitting
This is a flush fitting brass or black delrin dust plug that fits into the fill port on your BSA R-10. It is designed to keep dirt and debris out of your fill port while you are out and about.
It has a vent to allow air to vent off should you ever have a leak from your fill port on your R-10, preventing it from locking into your rifle.

These will also fit the HW100 and Steyr quick fill port.
