I made a change to the buffer system after removing the armaspec. As i mentioned in my last log, i removed the SRS and replaced it with the KYNshot with expected success since i have the KYNshot in my other AR9 builds. This time i added the addition 2.5 weights to make it a GRS system. I didn't notice too much of a difference if im being honest. The recoil with just the KYNshot buffer and flat spring was already really good. It probably gets about 5-10% better with the weights. The time i really did notice the difference was when focused on pulling the rifle into my shoulder firmly. The shots back on target felt the same as the standard hydraulic buffer system though so i wouldnt necessarily go out of my way to build a GRS system if i was looking to save some money or have the most lightweight rifle.
