Bren Gas Cylinder

[Joe H]

Guys,

Anyone have the specs for the I.D. of the Bren Gas cylinders. I found the spec for the piston head .626"-.6245". I'd like to be able to check a used cylinder before it is installed.

My interest is in rebuilding Brens into semi-autos in the US, particularly getting the gas system functioning properly. The semi's have an additional striker spring to compress so it's important to have full gas pressure.

I've read the thread about replacing the cylinder, no surpises there

Thanks,

Joe
