Reply To: MKl FX Bobcat .25 regulated.
Perhaps SPDRCER can offer some insight here. He had a .22 Bobcat Mk1 in the for sale section that has since sold.
I was under the impression that it was only the .30 cal that had the extra tubing external to the action. ( and they came standard regulated)
I thought the original FX regulator mounted inside the action. And the gauge then read the regulated pressure.
The new tube with gauge and front fill port would be the go like AZBOBCAT said.
