MPA BA Comp night vision bridge issue

Its a little tight, I can get card stock between the barrel and the top of the bridge but I dont know if its enough. I'm thinking of getting some gasket material from Napa in the morning to make shims. Eventually the rifle will be rebarreled when I kill the current barrel. Gasket material shims be good enough to get me some clearance and keep the bridge steady enough when I use a friends gear?

Barrels are like a tuning fork and flex more than one thinks
