Rainier Arms Forged Upper Receivers - Minus FA


Rainier Arms Forged Upper Receivers minus Forward Assist was made based on comments we received from customers who were looking for a lighter weight forged upper. These are designed to fit our forged lower receivers with color, texture, & machining but will fit all milspec forged lowers well. Comes complete with Dust Cover Installed. These uppers are "T - marked" engraved and have extended M4 feed ramps. Weighs a mere 7.5oz compared to 8.6oz on a standard forged upper.
