Yeah the 1145 fps. And I did not function test it prior and I’m regretting it now. I have another stock m4 I plan on taking out with me next trip to test along with the stuff mentioned above with my problematic m4. If both have issues I’ll leave it at that.

Also when it ejects the flitecontrol it’s really weak. Maybe 10 inches out of the gun. I’m wondering if that’s an indication of a spring conflict? Maybe with the buffer system not the mag? Maybe too much power for the bolt carrier for the lighter loads? My next plan was to swap back the oem trigger guard to illuminate that but I like your idea so I’ll try that! Thank you

I recently replaced the 5 round mag tube with a 7 round oem mag tube from benelli parts. I originally installed the recommended oem 7 round spring. Because I wanted to be compliant I also ordered a trigger pack from FFT and an A&S trigger guard. I actually assembled and entire trigger guard and left the oem untouched in case I ran into issues. Well…I ran into issues. Now the gun doesn’t cycle bird shot and certain buckshot ammo. It doesn’t like Flitecontrol. It’ll shoot 5 of the 7 then hiccup. It hardly ejects and the following round will get stuck on the lifter. I replacing the spring with a longer aftermarket spring from Carrier Comp but it didn’t make much of a difference. I have a feelings it’s the mag spring still?
