The following information will help you truly understand the differences between the design of the Revolution vs the AR10 platform.
The Colt 901 was the first attempt at reducing the size of the large action/frame of the AR10. DPMS mimicked the design and showed the GII two years later at Shot Show. Many other companies have copied this trend resulting in more “me too” products. They call this the “small frame” AR10. We will now refer to it as an “intermediate frame.”
The Revolution is an AR15 that is engineered to shoot the .308/7.62×51 cartridge. We started with the footprint of the M16 and added the overmatch force multiplying punch of the .308/7.62×51 battle rifle.
Firing pins (in order of left to right):
- M16
- .308 Revolution
- “Intermediate Frame” .308
- AR-10
The M16 is the shortest. The .308 Revolution & AR10 at the same length.
