PSA 9mm upper?

[mitommy]

I have a PSA 9mm, 16” upper. It has PSA handguard that I’m considering changing. Does anyone know if the PSA upper takes a mil spec barrel nut?  Has anyone done this change?  

I’m considering Foxtrot Mike Products Ultra Light Free Float Primary Arms Exclusive M-LOK Handguard - 15"
Has anyone had experience with Foxtrot Mike products?

I have their billet lower.  It's well made and I've had zero issues.  There's a lot of YouTube videos showing FM products.  I've not seen any complaints and their customer support is supposed to be outstanding.

You'll be fine switching to that handguard.  The upper receiver is mil spec and the FM handguard comes with it's own barrel nut.
