Build it. Run it. Log it.

More testing with 124 and 147gr. Only a few failure to ejects today. I also noticed that using the bad level gave some grief when chambering a round. Removing the mag allowed it to go into battery but still something to note. The gun ran well otherwise. I let a couple range friends fire it and they seemed to like it. One of my range friends that has show my other PCCs has the same feeling as I do, the AR9 with Kynshot 5501HD buffer feels smoother overall than the MAT9, even with the kynshot buffers in the MAT9. The Mat9 is sharper. Post range, did my normal clean up and inspection of parts. Notible wear on the ejector window and the inner frame is still wearing in.

Added the PROMAX to platy and noticed a little more felt recoil. Not sure if I like it. Im half tempted to put the 507 comp back on and use the promax for my dissent build.

Im happy to report that today I had an absolutely flawless range session with the MAT9 build. I reconfifmed zero on the green dot and sighted in the offset irons as well as the cheap laser. The gun ran nice and smooth. 147gr were a little smoother than the 124s. This was my first time using 147s but i feel this gun likes 147s a little better. I also dremeled out the buffer tubes and didnt not experience any failures with the buffer sticking. After all the problems, i think we are finally reliable. Will continue to test this week. I also added a phase 5 extended bolt catch i originally had on the build. Works well and no issues running it with the MAT9

Reliability is slowly increasing. Coming up on 1k rounds and its finally starting to cycle somewhat reliably. I went though 8 mags and only had less than 10 FTF or FTE issues across 8 magazines which is really good. I made sure to lube up the rails where the contact is and had minimal issues. Accuracy is good and recoil impulse is not bad. Im going to bring my angstadt build next week and see how the recoil feels back to back. Im pretty sure the buffered system is smoother.
