Any experience with PK custom AR uppers?

[Aaron who?]

Anybody ever buy or shoot 5.56 uppers built by PK Firearms? More specifically FN, but input on any brand that they build would be greatly appreciated.

Google isn't turning up too many reviews, so I thought maybe the Green Screen Brain Trust would have some opinions.

Thanks a bunch,

Aaron.

Never heard of them. I'd stick with one of the well known brands like BCM, Colt, etc...
