Adding weight beats things up both ways and plays havic on the weak buffer tube threads. Wait until you have one of those break. I saw Tubb's break, funny as heck. The weights increases recoil to the shooter. The high power and race guns that we assemble are timed for low recoil. The buffer spring compresion rate is one of the main players. There will be no damage with the increase power buffer springs as long as you count the stack dim of the wire dia and don't have the compresion bottom out. It will increase forward recoil very little and the bolt cam pin takes most of the hit in the cam area only shired with the face of the bolt carrier and the barrel extension which has the most impact. Change cam pins every 20000 rounds. Ejection location is a direct factor of bolt carrier rear thrust speed. The more important thing is travel of the spent case. The rule of thumb is 3'at 3 o'clock. You only need 19500 psi to cycle the actions so gas port location is targeted to that location. Bullet weight factor is key here, a 243 set up for 58gr bullets can use a +2" gas port location where as the same using 107s will use a +4" gas port location. There aint a good combo location for the 243 where as a barrel set for heavy bullets most of the time won't cycle the light ones. The weight systems and heavy buffers should be left to blow back systems on the pistol rounds. We had a guy put all that stuff in his rifle and his scores dropped in the rapid fire stages because he couldn't stay on target. He wouldn't hear of doing it the right way and then wanted to enrole in my civilian class, he didn't get in that ether. I never told him why because it put him out of winning the matches.MSH
