Rainier Arms released their RUC 22 .22lr Rifle upper last year but it seems to have flown under the radar. I just recently stumbled upon it and it seems to be pretty darn nice. It includes a Rainer Arms RAPTOR charging handle, Mission First Tactical stock and grip, Rainer Arms KeyMOD rail, forged upper and lower receivers, ALG QMS trigger, Battle Arms Development 45 degree Ambidextrous Safety Selector and other goodies. All that quality comes with a price however, the Rainer Arms Ruc 22 retails at $925. Check them out at RainerArms.com, they also sell just the upper separately.
Introducing our very own .22 LR rifle. Our focus was to develop a .22 LR rifle by utilizing the same highest quality AR compatible components and keeping the rifle true to the foundation of our .223 RUC design.
We integrated the same ambidextrous charging handle, the Raptor, as well as an ambi safety selector set up. It also features our Rainier Arms Force Rail 15″.
All materials used are of industry-leading standards, each weapon carefully and meticulously assembled with a limited lifetime warranty.
