I need a good vendor to heat treat these for me. I don't want to just send them to anyone with an oven, because of the nature of these parts containing an explosion right in front of the user's face.
The first person to refer me to the trustworthy heat treating vendor that I end up sending these to gets one of these bolts for free.
We're (sort of) almost done with the build! Now that the bolts are pretty much done, I am moving onto designing the interrupter. The build thread for the form 1 suppressor is currently ongoing at form1.org
Those are the last big things the gun needs! There will be some other tweaks and modifications here and there, but nothing keeping me from firing the rifle.
