I have the cva BH209 breech plug and do not like it to hard to clean so I mod one just like sabotloaders and ronlaughlin did and they work great and better for cleaning and when the flash hole gets to big you just replace the ventliner for $5.00 and not the breech plug for $25.00 for me this was the way to go for the dallors becouse I shot alot at the range and you have to check your head spacing for blow back and this is EZ to do

Clean the carbon from the plug with a 3mm or #32 drill bit and then adjust your head space. Should work flawless after the head space adjustment!
