[QUOTE="budlight, post: 2790763, member: 2939"] I don't have the test to post, but the highest peak pressure is after the bullet first starts to travel down the barrel and then with more bullet travel distance pressure decreases. Carbine length gas tubes are hit with @30,000 psi Mid length gas tubes are hit with @ 22,000 psi Rifle and even the rifle plus 2 inch at subjected to less than 14,000 psi and 11,000 respectively. These are not exacting figures because of the many variables. Like powder type, bullet weight , barrel temperature, and friction. This is why the buffer assembly differences and BCG weight. All my stuff is rifle and rifle +2 to not beat up my buffer weight faces...... You get higher velocity using longer gas system and that includes buying barrels with the smaller diameter gas ports [/QUOTE]
