I hear this a lot on this forum. I am still have yet to understand the concept. Let me explain.
First when firing a firearm, the gas from the powder pushes the projectiles down the barrel until it exits. While the projectile is moving through the barrel the gas continues to build until the projectile exits or all the powder is burned.
The amount of gas is determined by the powder and the volume of space that is has to burn. So the longer the barrel, the more gas. Now from what I have seen a read, most barrels have a standard size gas port and depending on the length they have standard gas systems, carbine, mid and rifle.
So why would say a BCA or PSA barrel be over gassed and a higher price barrel not?
The logics just don't make sense if all other components are the same.
