How to know how many shims for lvl 10

[Blackice7]

How do I know how many shims to put in for lvl 10. Should I keep adding till it leaks then take it down one?

[Dayspring]

Yep. I don't use any though. You don't NEED to use them, but to really fine tune it, you start using them.

[Cool fool!]

do shims make the trigger pull lighter? Adding more i mean.

Not w/ level 10. The ULT uses shims also and that may be what you are thinking of.

[BlackVCG]

Use zero shims unless they are needed.

[Cool fool!]

why use 0 shims unless they r needed?

[Cool fool!]

wat do shims do?

[Dayspring]

They alter the vent point of the bolt. It's adding space between where the vent hole on the bolt and the oring in the carrier sits.
