Alpha test for a slip trip of Matador Arms roller delayed MAT-9.

DISCLAIMER: My own upper broke during test. Both the upper and the slip trip lasted approximately 120 rounds. The Easy Take-down System (recoil spring guide unit and its retaining plate) cracked. The bolt also showed greater than normal friction inside the receiver. After online research, I found out many other people are having the exact same issue shooting it without the super safety. While I don't think my modification broke the upper but you still need to use your own discretion and INSTALL AT YOUR OWN RISK.

PRINTING INSTRUCTION: See thumbnail for printing direction. Print with support, 100% infill.

INSTALLATION: 1. Remove the rubber buffer on the EZTS. 2. Hook the slip trip over the 2 protrusions on the bolt. 3. Insert the bolt into the receiver.
