Main Differences between AR10 and AR15 (Assault Rifles)


The AR10 was created in Hollywood, California during the mid-1950s. This gun might have been created in Tinseltown, but it certainly wasn’t used in movies as a weapon for battle action heroes or as a prop for on screen stunt men. A weapons designer by the name of Eugene Stoner was the lead engineer for the creation of the AR10.

Stoner’s team developed the AR10 and it became the main product at ArmaLite weapons manufacturing company. However, it wasn’t well received in the arms market. ArmaLite decided to revamp the AR10 and created the AR15. While both weapons have similarities there are some differences.
