Tightbore for a L96 Mauser
 

I had a inner barrel for an L96. I can get it measured but what is the diameter on a tightbore? I know with paintball when u put a paintball in the barrel it should just nicely push through by blowing on it. Is there a similar way to know if its a tightbore? or just by diameter?

what is the dieameter for a tightbore supposed to be???

Tightbores usually range from 6.01, 6.02, and 6.03 in diameter. 6.04 is starting to run out of that range and further on.

If you're curious about your stock barrel on your mauser. I really doubt it'll be a tightbore as they're generally cheaped out on.

the random barrel i picked up i tried putting a bb through it manually but it was tight on it until i blew it through but it WAS quite dirty so i doubt its tight bore. but thanks for the info
