Folding mechanism for MPX with an AR style stock...

My buddy wants to get an MPX and put an AR style stock on it but have it fold. What are your recommendations for a folding mechanism for an MPX?

Thanks.

Correction, he does not have an MPX, he has some sort of system that does not use the buffer but is still an AR lower. My apologies (should be his dang it!) for the confusion.

So, if someone has an AR lower but doesn't use an AR buffer and they want to put a folder on, what do you like for that?

If he wants to use ar stocks, the law folder has good reviews.
The Ace ststem can use any of their stocks and is a good option as well.
Personally, if a buffer tube isnt needed, Id peobably opt for the Ace.

Might be newer options Im not aware of
