MCR Series AR type Rifles for the 21st Century

At Cobb we are proud to introduce the worlds first true multi-caliber AR type rifle for the 21st

century. The MCR (Multi-Caliber-Rifle) series rifles are chambered in a long list of calibers, from 9mm

to 338 Lapua and pretty much everything in between.

MCR 400 Rifle shown with optional equipment

MCR stands for Multi-Caliber-Rifle and it is built on the AR type design. MCR Semi-Automatic rifles come in

four different models which interchange with each other from one series to the next. To change calibers

for example from a .223 (MCR100) to .308 (MCR200) you simply change the upper receiver and magazine module.

To change calibers on the same series rifle from one caliber to another within the same series for example,

on an MCR400 from 300 Winchester Magnum to 338 Lapua Magnum you simply change out the barrel and bolt.
