Noting the weapon's poor precision, in the 1970s, International Association of Police Chiefs weapons researcher David Steele described the MAC series as "fit only for combat in a phone booth". That of the 9mm is approximately 1250, and that of the smaller MAC-11 in. 45 ACP is approximately 1090 rounds per minute. The original rate of fire for the M10 in. Ingram added a small bracket with a small strap beneath the muzzle to aid in controlling recoil during fully automatic fire. At the suggestion of the United States Army, the suppressor also acts as a foregrip to inhibit muzzle rise when fired. 45 ACP versions, as most loads are subsonic already, as opposed to special, low-powered subsonic loads usually required for suppressed 9mm weapons. The barrel is threaded to accept a suppressor, which works by reducing the discharge's sound without attempting to reduce the speed of the bullet. In addition, this design incorporates a built in feed ramp as part of the trigger guard (a new concept at the time) and, to save on cost, the magazine was recycled from the M3 Grease Gun. The M10 fires from an open bolt, and the light weight of the bolt results in a rapid rate of fire.
This allows a more compact weapon and balances the weight of the weapon over the pistol grip, where the magazine is located. The M10 has a telescoping bolt, which wraps around the rear face of the barrel.
A notched cocking handle protrudes from the top of the receiver, and turns the handle 90°, locks the bolt, and acts as an indicator the weapon is unable to fire. Both guns are considered to be collector’s items now, but since the M11 is more readily available, it won’t break the bank.The M10 is built predominantly from steel stampings. This makes the M11 cost about half of what an M10 usually does. Even less copies were made of the M10 models. SWD reported manufacturing 17,000 of M11/9 and 3,800 of the. Of all the MAC models, the M11/9 is the most common. We all know that the rarity of a gun affects its cost. The one-stage suppressors are less valuable. If you are considering purchasing one of the two guns, look for sets that come with the two-stage suppressor. Later on the single-stage suppressor was manufactured but it used Nomex wipes which ended up being very unpopular due to the need to replace the wipes too often. The first to be introduced to the market was the two-stage suppressor that featured a wipeless design. There is a single-stage suppressor and a two-stage suppressor. If you are a collector who wants all of the original accessories, then you are probably interested in learning about the two suppressors that were built for the guns. Unfortunately, replacements are becoming more rare and expensive. With the M10, you get the steel magazine. Luckily, you have the option of purchasing a conversion kit and then being able to use a steel mag. If you find an M11 with a Zytel magazine be prepared for reliability issues. If you purchase the MAC 11 you can get a Zytel mag or a steel one. The M11 and M10 also use different magazines. You may be wondering about the reliability of a thinner sheet metal, but the M11 has proven that it holds up just as well as the M10. The weight and size of the M11 makes a big difference when trying to conceal it. This is because it is constructed with a thinner gauge of sheet metal. As mentioned earlier, the M11 is much lighter than the M10. If you are looking for a 9mm machine gun and cannot decide between the 10 or the 11, then there are a few more differences to consider. The Difference Between the MAC 11/9 and the MAC10/9 380, but the M10 also weighs twice as much and has a slower muzzle velocity. Which gun to get is really a matter of preference in size and caliber. 380 caliber MAC 11 weighs only 3.5 pounds, fires 1,200 rounds per minute and has a muzzle velocity of 980 feet per second.
The maximum effective firing range is 50 meters and the muzzle velocity is 280 feet per second. 45 caliber MAC 10 weighs 6.26 pounds when empty and it fires 1,145 rounds per minute. There are many differences between the two MACs, the biggest being their size, caliber, construction, and manufacturer. 45 ACP M10 and then later made the MAC 11 in a 9mm and a. Little did Ingram know, his M10 design would become very popular. He built it with as few working parts as possible to reduce cost and increase reliability. His goal was to make a machine gun that was compact, lightweight, affordable, and reliable. Ingram designed the MAC 10 in the early 1970s as a compact machine gun.
