Does anyone know the breach inside diameter of the FX Maverick 25 and 30 caliber barrels



Thank you in advance

If I am correct, and understanding your question, someone will surely tell me, they are the same no mater the caliber .177-.35

Please forgive my ignorance

My question should have been with relation to the inside dismeter of the 25 and 30 caliper liners respectively



I am truly sorry as I am new to FX barrel and sleve nomenclature



Thank you all in advance
