Edit..... UPDATE, turns out I unknowingly had an armalite pattern BCG installed in a DPMS pattern receiver.....
Today my 6.5 upper build had a kaboom, details
I pieced this together, this wasn’t a factory gun
Stag 10 upper receiver, dpms pattern
Stag 10 22” 6.5 barrel, rifle length gas system
Brownells 308 BCG, headspace was checked
Stag 10 lower with rifle buffer and spring, luthar stock
The kaboom happened on exactly the 75th round fired, the rifle ran flawless until the kaboom and was grouping under 1 MOA with factory ammo when I did my part. I was shooting federal 140gr non typical ammo when the kaboom occurred.
Pressure vented down the mag well and destroyed a 10 round Pmag, I had my hand on the mag and my left pinky finger has a small cut and feels like it was hit with a hammer but no other injuries, thank god.
I was shooting 5 round groups and this was the last round fired for the grouping, it did not slamfire, I pulled the trigger, I have no idea what went wrong??
