Broke ejector while adjusting
Got my Mat-9 upper in today and started heating up the ejector so I could adjust it and it broke. 😭
Tips on ejector adjusting?

I have the proper two position receiver extension on a different lower as well, just waiting for the Form 1 approval before throwing this upper on it.
The lower waiting for it also has a faux serial with Heat’s release date.
FM9 lower. Had a stove pipe, and it seems the bolt slamming the shell into the bolt catch has bent it
I sent a dagger frame in for repair back on April 7th. On April 24th, I got an email that it was being diagnosed. The initial email said to allow 30 days for diagnose and repair.
Hey yall,
I have a spike tactical and a Foxtrot Mike FM9 lower. Both have LRBHO.
I have an upper from Pro2A tactical coming in that I want to run a Super Safety in. Which would be better off for this build?

Picked up Sierra 5 yesterday, a little nervous reading the issues people had with them.
I tried searching but only saw the length on the Mat 9K.
I ordered my upper but since it’s gonna be a while I figured I would start on my form 1 early so when it arrives I can throw the stock on it.
Can anyone tell me what the length of the Mat-9 is without a stock?
