Amazing quality and service.

Review by Whitney J. on 27 Feb 2025 review stating Amazing quality and service.
Great rifle, shipping was fast and got to my FFL in just a few days. The rifle quality is above and beyond anything you could possibly ever need. I ran it suppressed and it ran quite and smooth. The recoil on this rifle is ridiculously smooth when suppressed. I’ll be buying another rifle for my wife from Rainer soon.
