Rainier Arms (https://www.rainierarms.com/?page=shop/detail&product_id=4359) is starting to offer custom Uppers built around their new FORCE Rail and RAC Brake. Some of the first are these 14.5 and 16" Uppers. These uppers offer midlength piston system built around an Adams Arms kit and Voodoo Innovations barrel. Check out Rainier Arms' webpage (https://www.rainierarms.com/?page=shop/detail&product_id=4359) for more information or to order.
Description:
Our Piston Series are built in collaboration with Adams Arms Piston Kits. The 5.56 Midlength Base 14.5" Upper is a standard mil-spec upper that incorporates the patented Adams Arms technology and Rainier Arms Force™ Free Float System. The midlength piston system will give you the benefits of a longer forearm by giving the user a longer, more ergonomic grip, a longer sight radius between the front and the rear sight for quicker sight acquisition and less felt recoil. The piston system parts and the barrel have been treated with salt nitride Meloniting process making them harder and more corrosive resistant than hard chrome. Our Piston Series system allows you to have an upper that will run cleaner, cooler, and longer than any other AR upper you own.
