Dear smart people. I've got a .875 diameter barrel and I see plenty of gas blocks for it. But I don't see where they state port size. Other than an adjustable block, How do find the port sizes?
A lot of assumptions can be made with varying degrees of accuracy. Barrel diameter has no effect on gas port diameter. Things that do affect gas port diameter - barrel length, gas system length, caliber... All have an effect on port size selected by the maunufacturer. As stated, measuring is best. You can buy a small selection of gauge pins in the range you need on Ebay or from McMaster-Carr without breaking the bank.
