Here is a devoid plug for a SBA4, I created this because I abused my old SBA4 and it was became uncomfortable to shoot with in a rifle configuration, now it's less uncomfortable. I plan on making further improvements.
Was made in CATIA.
Print at your own risk, I printed with 100% infill with supports.

Keep in mind...
NFA rules apply. The use of this plug may constitute a re-design of the brace. It is your responsibility to know the rules surrounding the use of the brace for your particular firearm.
