Is carbine length or mid length better?
On a standard 16 inch or an 18 inch barrel, we recommend a mid length gas system. On a 14.5 inch or shorter barrel, we recommend a carbine length gas system. With this shorter barrel, there is less space between the vent hole and the end of the barrel, so the correct amount of gas will enter the gas tube.
Can you put a mid-length handguard on a carbine?
Generally, you need to match the handguard length to the gas system. But if you use a low-profile gas block, it is possible to put a longer handguard on a shorter gas system – such as a carbine handguard on a pistol gas system, or a mid-length handguard on a carbine gas system.
Does the military use mid-length gas system?
The M16 uses a 20-inch barrel and gas system, but the M4 designs were crunched down to fit a 14.5-inch barrel. The M4’s port pressure measured at 17,000 psi, while the M16’s was at 10,000 psi. Many civilian clones of the M4 utilize longer barrels, but also place mid-length gas systems on their custom-built designs.
What is a carbine lower?
A lower with a carbine length buffer system, and usually a length adjustable stock. A “rifle lower” would likely reference a lower receiver with a rifle length buffer system and a fixed stock.
How long is a standard AR upper receiver?

Which is better mid length or carbine length gas system?
As you can see there are wide ranges here, typically the closer that the barrel length is to the middle of the range, the better it will function (example 14” barrel with a carbine length gas system). It’s worth mentioning that there are factors that can affect the gas system, beyond the length of the system.
What does mid length mean on a rifle?
The mid-length designation isn’t about the barrel length – other than the fact that is not a full rifle-length barrel (20″). Mid-length actually refers to the length of the gas system (placement of the gas block and length of the gas tube), not the barrel or overall length.
