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)

A 5.56mm 10.3″ barreled sub-carbine/PDW featuring the new Colt side-folding stock. It is able to use an upgraded gas impingement system or the Colt Piston System (CPS)

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.

    Too bad that Colt's new SCW' folding stock will dump the magazine when the stock is fully extented, buttplate is down, and the stock is hinged forward to the left. This most likely carry state that will enable the stock to be rapidly deployed. The large button that locks the buttplate hits the ambidextrous mag release with the slightest tap. Colt's sales force does not want to hear about it. Their reply is that "training will solve all problems!"
