Bushmaster has recently released its civilian version of the Adaptive Combat Rifle and displayed both the Civvie model and the so-called "Enhanced" version of the ACR intended for military customers.
Bushmaster rep Ryan Smith went through the features of the gun formerly known as the Magpul Masada and explained the Bushmaster was working the state national guard and law enforcement customers, while Remington was working the military deal.
As you well know, the Army is in the middle of an internal look at whether to replace the M4 as the standard issue carbine, and the ACR would be a strong candidate for the job. The ACR is the only rifle in the running that can undergo a quick and easy caliber change. A source with Bushmaster who declined to be quoted on the record said that Remington plans to offer the ACR in both 5.56mm and 6.8mm.
The Army could buy the Improved Carbine and Personal Defense Weapon all in one package...?
