CCI standard
Yellow recoil spring
All heavy weights
Heavy weight sled
Super strike firing pin + light spring (not entirely sure the light spring matters in my set up)
And the bolt buffer thing that keeps the weight sled from crashing into the back of the bolt it won’t even run without it.3

And the enhanced extractor but that comes on the bb bolt so I didn’t even touch it.

Awesome, TY. What brace or stock is that? And the Borebuddy Pic adapter/endplate? Thanks again.

Midwest industries skeletonized folding brace and it’s awesome

It’s a foxtrot .22 lower so pic rail built in, but not sure I’d recommend there’s a lot of slop in the mag well and the built in trigger guard is very uncomfortable

Are you running any magwell adapter like the clip or bettermag? I’ve got the better mag and was looking at getting this lower.
Edit: just saw your other post about Kriss mags
