I am asking this because I have a new build that is short stroking... Mainly failing to lock back on the last round. Anyway hear it goes.

What is the standard diameter for the the Mushroom head portion of the gas tube ( the portion that enters the key)?.

I have two brand new BM barrels and the gas tube heads (end that enters the key) both  seem much smaller than what I am used to looking at . It was noticable before I even shot the gun, and now that I am getting this short stroke issue I am thinking that may be a place to start! Blow by???

Thoughts, measurements, specs would be appreciated???? Thanks?
