I want an MP5 clone.
I was looking at the PTR 9c

What are some of the better options out there?
I saw Zenith, and POF but not a fan.
I really don’t want a threaded barrel


Here are my must haves:
Needs to be USA made because I’m going to Form 1 SBR it and don’t want the hassle of the 922r law.
Has to have the tri lug for my suppressor.
I prefer a welded rail for optics not the claw mount.
Has to be reliable

So what are my options? Who makes the best?
