Over the past few months Colt has been unveiling a variety of new AR-15 firearms. If a replacement for the M16 or M4 is chosen they want it to be a Colt. To ensure this designed a range of weapons that should cover all bases. David @ Defense Review has been relentlessly covering the new firearms.

Many of the improvements Colt have developed have been applied to all these guns, I won’t list them all, click the links to read the full details.

Colt Sub-Compact Weapon (SCW)

Colt ACC-M (Advanced Colt Carbine-Monolithic)

This is basically an upgraded M4. It features many small improvements over the M4A1 and Colt’s new monolithic rail system. If it was adopted it I think it would probably be named the M4A2.

Colt Advanced Piston Carbine (APC)

David calls this the HK416 killer. It utilizes the Colt Articulating-Link Piston (ALP) system.

Colt Advanced Hybrid Carbine (AHC)

This carbine features a hybrid gas impingement and gas piston system. I am very interested to see how that works.

Colt Infantry Automatic Rifle (IAR)

I covered this a few weeks ago on the blog. It is a light machine gun and Colt’s entry into the Marine Infantry Automatic Rifle competition.
