Is a Remington model 11 forearm interchangable with a browning?

The Remington Model 11 and Browning Auto-5 share a similar design, as the Remington is based on John Browning's patent. However, their forearms are not directly interchangeable due to differences in manufacturing tolerances and slight design variations. While they may appear similar, it's best to use parts specifically designed for each model to ensure proper fit and function.
