This is a MP5 endcap adapter that utiziles an H buffer and whatever SBI spec stock or brace you wanna throw on it. I Have personally only tested the SBT-evo and the SBT5A braces, they function with minor fitting.

Credit goes to AllArms LLC for their MP5 AR buffer tube adapter on myminifactory and massive credit goes to @BrokenBullets:9 for his SBI spec that I ripped to make this. Check him out for some 3d printable UMP style braces, along with all of his cool cz scorpion based projects!

Any questions can be left below, or feel free to DM me on twitter @UberPoor
