PDI palsonite cylinder question.

Hello everybody, I am currently in the process of figuring out the upgrades I want in my VSR and I have a question.

I know that the laylax teflon cylinder makes the bolt pull significantly lighter, does the PDI palsonite cylinder do the same thing?

Also does the PDI vacuum piston really make a great difference as far as accuracy goes? Or is it not really worth it?


Thanks in advance, Josh
