Plug for all Milsig owners who decide not to use BRH (Bolt Reset Handle).
Bolt reset handle is used only in case that bolt got stuck in front position. Bolt stuck can happen when you break First Strike round in breech (due to the hardness of material FS shell is made of).
If you do not shoot First Strike rounds, than you can safely remove BHR from your marker and use the BHR Plug.
