MULTI-CALIBER RIFLE (FOUR CALIBERS)

Windham Weaponry’s RMCS-4 Rifle offers four calibers in the same AR platform with a simple barrel change. The key is on the underside of the MCS upper receiver (shown far left). Once
the barrel retaining block is unlatched and moved forward, the barrel retaining arms rotate out to release the barrel - ready to be replaced with the barrel of your choice.

In the MCS lower receiver, drop the trigger guard and push the mag release button. One caliber’s mag well slides off and another slides on. Then, if required, the appropriate bolt carrier
is inserted into the upper, and with the appropriate magazine and ammo, the rifle is ready to fire.
