Great service.
Sent out a pvs-14 parts kit and a tube and got back a very clean working unit. Sourcing my own parts and having them built by a professional saved me a few hundred bucks and I encourage you to do the same.
Shipping was quick and easy, and I've had zero problems with my finished unit. The spec sheet they give you is a nice touch too.
Note: tube photo kind of a fuck because camera wouldn't focus properly.
