I'm a babe in the woods on this topic.
I have a grand total of one lonely Nighthawk.
It was built by KJ Phillips.
I have yet to find a single flaw with the gun. I've looked hard, too.
Granted, I don't have a pile of rounds through it yet...less than 500. The gun is to my liking in every way.
As far as my Nighthawk deficiency....I'm waiting on Nighthawk to resolve that. 12 months into a wait on a TRS-Comp order now. Hopefully it'll arrive soon. I didn't request any specific builder.....but hope it's on par with first.
