I want to give a shout out for RB Precision. They are a firearms related business in Preemption, Illinois. I have done business with them for a couple of years. They are a distributer for Rock River Arms as well as DPMS. They also have custom products for AR rifles. The lady in charge is named Krista. Everytime I have talked with her she has been friendly and genuinely interested in providing the help I needed. Their prices are usually lower than anyone else that I have contacted. I contacted her in the fall of 2010 inquiring about an AR for my son-in-law. He is currently serving in the Marines and will be getting out this December. I want to give him an AR similar to his duty rifle. This rifle will be a thank you gift for him serving our country. When I told Krista what the rifle was for, she said she would waive the shipping charges since the rifle was for a serviceman. She did not have to do that. No other company that I order from would have even offered. That gesture by Krista tells me volumes about the kind of people who own RB Precision. Next time you need a rifle or parts for an AR consider contacting them, I think you like them also.
