Rainier Arms Forged Upper Receiver – Initial Impressions
This is a very high quality mil-spec forged upper offering from Rainier Arms. They are a local company, so having them in my state is a huge bonus for me. If you want to have a quality upper to base your build off of, this is definitely a solid option from a great company with a very good reputation.
