In addition to aligning the gas system, the index pin also separates the barrel’s torque while firing from the fastening system.
It’s in there for multiple reasons.
You can get by without one, but Aero is a good company and will take care of it.
Now, the only real reason I’m here is to get the story on how you broke the pin off.
Jeez! Remind me not to shake your hand!Nothing crazy, I wasn't paying attention and switched torque mode off on my wrench so I just tightened too much.
I will be surprised if there is NOT any damage to the receiver simply due to aluminum being softer than the steal pin. Plus the fact that it would take a whole lot of torque to brea the pin which very well could have stretched the receiver threads.
LMAO anything from 8" to 11" barrel would cause me to form 1 for a integral suppressor.I got a little impatient and I decided to test it. It functions fine, and accuracy seems good for a run of the mill 8.5" barrel and 147gr ammo. I was able to consistently hit 18" plates a 100 yards...
