Last updated August 2026 · By Nick Hall, has run a Colt 6920 hard enough to resent the safety selector every time the support hand did the work
Quick take: Colt has updated its direct impingement M4 platform with fully ambidextrous controls and released it as the M5 Carbine. It went out with almost no fanfare. For anyone who has shot a Colt from the wrong shoulder, it is the most useful thing the company has done to the platform in years.
- What it is: The M5 Carbine, a direct impingement AR platform carbine built on Colt’s legacy M4 architecture with fully ambidextrous fire controls.
- Price: Positioned in Colt’s carbine line rather than as a premium halo product. Confirm current pricing with a dealer, as launch pricing has moved.
- Where: Colt dealers. The launch was quiet enough that stock is patchy and many shops have not catalogued it yet.
- Why it matters: Colt has left its controls essentially unchanged for decades while the rest of the market went ambidextrous. This closes that gap.
Colt spent twenty years being the company that made the rifle everyone else copied and then declined to copy anybody back. Meanwhile every serious competitor shipped ambidextrous safeties, bolt catches and magazine releases as standard, and Colt buyers bought aftermarket parts to fix a rifle that had cost them a premium in the first place.

What Ambidextrous Actually Buys You
The argument for ambidextrous controls has never really been about left-handed shooters, though they benefit most obviously. It is about the fact that shooting from cover, around a barricade, or with an injured hand means running the rifle from whichever shoulder the situation allows.
A right-handed shooter working a left-side barricade has to break their firing grip to reach a right-side safety, or roll the rifle, or expose more of themselves than they want to. An ambidextrous selector removes that decision. So does a bolt catch and a magazine release that can be reached from either side.
This is not a novel insight and it is not new equipment. It has been standard on competing carbines for well over a decade, which is precisely what makes Colt’s absence from that consensus so conspicuous.
Why Colt Took So Long
The uncharitable read is inertia. The more accurate one is federal acquisition contracts. Colt’s business has been anchored to military and law enforcement procurement for decades, and those contracts specify a configuration and then punish deviation from it. A rifle built to a government specification does not get redesigned because commercial buyers would prefer it.
The commercial consequence was that Colt’s civilian rifles inherited a control layout optimised for a 1990s procurement document. Buyers paid the Colt premium for the rollmark, the barrel and the reputation, then spent another hundred and fifty dollars on an ambidextrous safety and a bolt catch to bring it level with rifles costing less.
Direct Impingement Is the Point
Worth noting what Colt did not change. The M5 stays direct impingement. There is no piston, no proprietary operating system, no reinvention of the gas key.
That is the right call. Direct impingement is lighter, cheaper to maintain, more accurate on average and vastly better supported by the aftermarket than any piston conversion. The market spent a decade being told piston guns were the future and then quietly went back to buying DI rifles, because the problem pistons solve is mostly a suppressed short-barrel problem and most people do not have that problem.
Colt updating the ergonomics while leaving the operating system alone is a company correctly identifying which part of its rifle was actually dated.
What the Rollmark Is Actually Worth
Colt occupies a strange position in the American rifle market. It is simultaneously the most historically significant name on an AR-15 and, for the last fifteen years, rarely the answer to which rifle should I buy at this price.
That gap between reputation and recommendation is what a launch like this is trying to close. Whether it succeeds depends on execution rather than heritage, because the buyer who does not already care about the rollmark has an enormous number of alternatives and knows it.
What Colt Still Charges For
The uncomfortable part of any Colt launch is the price conversation. Colt has never competed on value and the M5 does not change that, which means a buyer is paying a premium over rifles that match or beat it on specification from makers who ship ambidextrous controls, better triggers and free-float handguards as standard.
What the premium buys is real but it is not mechanical. It is a chrome-lined barrel built to a military specification, a company that has been making this rifle continuously since before most of its competitors existed, and a rollmark that carries meaning for a certain kind of buyer. Whether that is worth several hundred dollars is a question only that buyer can answer, and plenty of them answer yes without embarrassment.
Who Should Care
Anyone who was already going to buy a Colt. That is the honest scope. This does not make a Colt the best value carbine in America, because it was not competing on value before and it is not now.
But if you want a Colt specifically, for the rollmark or the barrel or because you carried one, the M5 removes the one concrete functional argument against buying new. And if you are cross-dominant or left-handed, it moves Colt from a rifle you had to modify into a rifle you can buy.
The quiet launch is the odd part. A company with Colt’s brand recognition addressing its most persistent product criticism should have made noise about it, and instead the rifle appeared with almost no announcement and patchy dealer stock. Whatever the reason, it means a lot of the people who have been waiting for exactly this rifle still do not know it exists.
Colt built the rifle everybody copied, then spent twenty years refusing to copy anybody back. This is the company blinking.
Frequently Asked Questions
What is the Colt M5 Carbine?
An update to Colt's legacy direct impingement M4-pattern carbine, adding fully ambidextrous fire controls while keeping the direct impingement operating system unchanged.
Is the M5 piston operated?
No. It remains direct impingement, which keeps it lighter, cheaper to maintain and fully compatible with the enormous AR-15 aftermarket.
How is it different from the Colt 6920?
The core rifle is closely related. The meaningful change is the control layout, which is now ambidextrous rather than the traditional right-side-only arrangement.
Is it worth upgrading from an older Colt?
Probably not on the controls alone, since an ambidextrous safety and bolt catch can be fitted to an existing rifle for well under two hundred dollars. It matters most on a new purchase.
Does it take standard AR-15 parts?
Yes. It is a standard direct impingement AR platform, so handguards, triggers, stocks and optics from the general aftermarket fit as normal.
Why does ambidextrous matter if I am right-handed?
Shooting around left-side cover, from a vehicle, or with an injured hand all require running the rifle from the other shoulder. Ambidextrous controls remove the need to break your firing grip to do it.
Where can I buy one?
Through Colt dealers, though the launch was quiet and stock is uneven. Many shops had not catalogued it in the first fortnight.
