Choosing an M1 Carbine Suppressor: Everything You Need to Know

One of the often discussed, but seldom applied rifles adapted for suppressor use is the legendary M1 Carbine, the classic light infantry rifle designed for the military in the 1940s. We say discussed because this rifle is not as easily suppressed as others, which we’ll get into in a moment. Can it be done? Definitely, and we will point out the best options for doing so. Picking the right suppressor is the key here, as the M1 Carbine is a tricky platform to start with. Done right, however, can yield amazing results. Here is everything you need to know when choosing an M1 Carbine suppressor.

M1 Carbine: a Brief History

The M1 Carbine rifle entered service with the U.S. military prior to World War II, and was used throughout the military into Vietnam. It was designed as a lighter alternative to the M1 Garand, with lighter ammunition, coming in at roughly 7.5 pounds. The initial idea came about in 1938 when the military expressed a need for a light rifle for infantry. The formal requirements were set in 1940 and Winchester took on the task of design. Ed Browning, John Browning’s half brother, served as the lead designer, coming up with the Winchester G30 rifle. David Marshall Williams completed the design by adding a short-stroke gas piston design he had developed with a rotating bolt design from the M1 Garand.

Winchester developed a new cartridge based on a 110-grain .30-caliber bullet. It is a straight-wall, rimless cartridge that would go through some trial and error before being completed, becoming known as the .30 Carbine. Effective range for the .30 Carbine is around 200 yards. Energy and velocity are close to that of the .357 Magnum. There are some newer load options for the .30 Carbine, but most have a similar performance due to the rifle’s low rate of twist (1:20). All of this adds up to a rifle platform that is tricky to suppress while not hurting performance.

During World War II, there was a developmental program at the Royal Small Arms Factory in Great Britain to develop a suppressed version of the M1 carbine for use by the US Office of Strategic Services and the British Special Operations Executive. While the guns never really got past the development phase, the fact that they exist is proof of concept that you can indeed suppress the M1 carbine today.

Modern Uses of the M1 Carbine

Today, most M1 carbines are vintage guns from the middle of the 20th century; they’re widely seen as collectibles and many see them as “off-limits” for modification to use with a suppressor. Thankfully, there are companies out there making brand new M1 carbines that are more affordable than the vintage ones and you don’t have to feel guilty about modifying them to suit your needs.

Modern M1 carbines are a ton of fun to shoot and people use them for competition, range plinking, sometimes in defensive capacities, and, where legal, even for hunting. Because of the wide range of applications, it’s easy to see why one might want to suppress an M1 carbine.

Choosing the Best M1 Carbine Suppressor

There are a lot of different factors that need to be considered when choosing the best suppressor for an M1 carbine. This includes things like sound reduction and decibel ratings, overall weight and length, durability of the construction materials, and price.

Benefits of Suppressing the M1 Carbine

If you really want to shoot your M1 carbine and do so more quietly than normal, the only way to achieve that is by adding a suppressor to it. Shooting suppressed is a unique experience, and a suppressed M1 carbine is definitely high on the list of unique suppressed experiences.

Obviously, this would be better suited to a modern production gun than a vintage one both for the historic value and the build quality. You’ll need to have the barrel threaded to accept a suppressor, and we offer that service in-house, too.

If you need a couple more reasons why you’d want to suppress an M1 carbine, we have you covered.

Decibel Reduction

Suppressors cut down the sound of gunshots on all guns, including an M1 carbine. It won’t be silent, but it will be quieter. Whether you’re shooting on an indoor range or just having a day full of fun, it’s always better when you can do it more quietly and not have to worry about damaging your hearing or the hearing of those around you. A well-built suppressor will help knock down those decibels and protect your ears.

Decreased Felt Recoil

Less felt recoil is a bonus feature of suppressors. While the M1 carbine’s .30-caliber cartridge isn’t known for its heavy recoil, it’s nice to know that you can still cut down on the recoil if you’re going to be shooting a high volume number of rounds or if you’re introducing someone new to the gun or shooting in general. Less felt recoil makes for a more pleasant shooting experience.

Less felt recoil also translates into less muzzle rise. When combined, a decrease in felt recoil and less muzzle rise can lead to more accurate shooting and faster target reacquisition for additional shots. All of which adds up to good things.
