For the new barrel length on AR-15/AR-10 barrels, we will measure the barrel length from the closed bolt face to the muzzle. SPECS: Thread Lengths: AR-15/AR-10: 0.625″ .22 LR/WMR: 0.440″ All barrels will be dialed in when threading so the threads are cut concentric within .0005...
Most M16 barrel lengths are between 14.5 inches (military M4 barrel) and 20 inches (classic civilian AR-15). The most widely-used civilian barrel is probably the 16 inch one, mainly since the 14.5 inch one is not legal in all states. Some civilians purchase a 14.5 inch barrel, but add ...
These barrel lengths are not written in stone, and there are anomalies: The mate to that 21-inch-barreled 7mm-08 I mentioned is a .257 Roberts that wears a 23-inch barrel. My CZ .375 H&H has a 25-inch barrel. For most of us, for most purposes, the range probably runs from 20 ...
If you look at AR 15 barrels, you will see them listed with 4 different lengths of gas system. Pistol, Carbine, Mid, and Rifle length. And if you laid 4 barrels out side by side, you would notice that the ports are all different distances away from the chamber, rifle being the furth...

The wide base of such a cone is firmly connected to the respective base material and thus also determines an upper limit for the areal density of the asperities. The lengths of the cones and their bottom diameters can be different, related to each of the two tribo-surfaces, but they are ...
If you search the web, you can find quite a bit of data on 223 Remington and 5.56 NATO ballistics from 20″, 16″ and 14.5″ barrel lengths. This makes sense since these are the most commonly used in the AR style rifles. Intermediate barrel length data is som...

I think you would need to look at the full literature, for every person that pulls selected articles that point to ECS being higher than in AR5, another person can put up references that say the opposite. The IPCC report is a good middle ground. The evidence for this is there are a ...
In addition, it is sometimes be desirable to swap out barrel configurations and/or lengths depending on changing field conditions or combat environments encountered in which the automatic carbines will be used. For example, shorter lighter barrels are often desirable for close-quarters engagement like...
