I only have experience with Mirco direct pf’s that i have installed. I Didn’t have any issues during install or in the time since - of course thats not to say things cant change, only time will tell. So far so good.

I don’t own any JJP’s or am one of the unfortunate people who had issues with their pf’s. I am not a Mirco fanboy, or any others for that matter. But i think the poll option for the mirco direct will not only reflect the quality of pf - it will reflect the quality of install.

If someone wails on t nuts to drive them in i would not worry about cracks - i would expect them. They will form along inserts or between closely spaced through holes. Same with installing topside screws. You really need to remove the clear away from the threads. Otherwise they can grab and lift or crack clear around the holes. This applies to any repro pf not just Mirco’s.

I would post my PM between me and Mirco when i asked him that very question before i populated the pf. But i dont want to get in shit with the Mods!

Basic response - ‘swing away Merrill’. They use a special clear coat system which allows for immediate installation.

I only asked about the ones he sells direct. No idea if it is a different system for the JJP’s. And if anyone installing is still unsure they should ask Mirco too. I have no affiliation!
