14.5 LMT MRP-L upper with a precut Geissele SSAE-X trigger running the AS Designs ARC-Fire. No modifications done to the upper not the lower.
Running a JP SCS buffer system with an H2 buffer weight and the 15-100 spring setup. Should I run a weaker spring to reduce the ROF? Currently sitting at approximately 786 RPM. Its that good? Bad? This is my first FRS.

Edit: added the ROF of the setup.

Like the title says, my ported barrel burned my trijicon tritium night front sight on its first range session while zeroing it. I had to pain it with a white marker.
