Tuning Gen I FX Crown convert dovetail to picatinny

I saw those but they had mixed reviews, likely from people who don't know what they are doing. Thanks, I'll give them a try.

I also use these. They typically offer the lowest adapter rise and have been rock solid on my D48 springer as well as on PCPs. 

For the most secure fitment (peace of mind really) I'll let a little VC3 dry on the inside clamping lip.
