22LR Chamber Plug

thingiverse

I created this chamber plug so I can soak the bore of my 22LR. There is a groove in the body to insert a 1.5 x 4 x 7mm o-ring to create a seal. It has a rim that will allow you to use your bolt to extract the plug. Instructions: place o-ring in groove, insert into chamber, gently close bolt, fill bore with your favorite solvent. I made this for semi autos not bolt guns, simply use the recoil spring to hold the bolt closed and seal the chamber
