👉 Rifle length gas system with carbine stock?

With uppers, the term rifle refers to the length of the gas tube. A rifle gas tube/system is longest, mid length gas tube is a little shorter, carbine shorter still. With lowers it refers to the length of the buffer tube and the design of the buffer itself. The carbine buffer tube and buffer are shorter than a rifle buffer tube and buffer.

👉 Carbine gas tube length?

Advantages of Carbine Length Gas Systems The carbine gas system is more compact than ...

Carbine-length gas systems: A carbine length gas system is the most common and has a gas tube about 7.5 inches long. AR-15s with shorter 10-18-inch barrels function their best when paired with a carbine-length gas system. Mid-length gas systems: Mid-length systems are a little bit longer and measure in at approximately 9.5 inches. Carbines with barrels 14 to 20 inches long will deliver optimal results with mid-length gas systems.

Carbine-length gas systems are better suited for close-quarters because the barrel is shorter and more compact. This makes them easier to maneuver around tight spaces with less obtrusive barrels. Carbines are also lighter and great for rapid-fire shooting.

The below chart shows the typical gas system lengths (distance from receiver to gas port) ...

Both of these rifles have 16" barrels, but the gas system length (marked here by the position of the front sight tower) is different. The M4 carbine has a 14.5" barrel and a ‘carbine’ gas system, meaning the gas port is at the 7.5" mark. Civilian clones of the M4 usually have 16" barrels for legal reasons, but traditionally keep the carbine gas ...

The DGI family's most common gas-tube lengths are carbine, mid and rifle. Actual sizes vary slightly, but the gas tubes used are typically 9.75, 11.75 and 15 inches long, respectively. There are...

There is nothing wrong with this length, and a carbine length system is well suited to operate with a barrel this length. The civilian market did want the ability to attach a bayonet to match what the military was using, so to achieve this the mid-length gas system was created to allow a bayonet to properly interface on a 16 inch barrel. Once again, the bayonet continues to dictate gas port location and barrel length.

Carbine gas systems work perfect for any barrel that's 10" to 18" long. Mid-length gas systems work best for 14" to 20" barrels, and rifle gas systems are reserved for 20" or longer barrels, only. Note the distances of the gas port to the chamber, too. The shorter the distance, the greater the amount of harnessed energy.

In other words, a 12.5'' barrel with a mid length gas or a 16'' barrel with a rifle length gas is not going to cycle the same as a 10.5'' carbine gas. A mid length system has lower pressure than carbine. A mid length has less dwell time than carbine.

Let's assume a 16" barrel with carbine-length gas system. Looking at the table above, your gas block rear end (closest to the shooter) will be at 7 5 16" away from the Upper Receiver. So you need to choose a 7" free-float handguard, and you'll have about 5⁄16" of clearance between the handguard and the gas block.

On a 14.5 inch or shorter barrel, we recommend a carbine length gas system.
