Finished my MAC-9 build with the velocity upper and lower parts kit. Printed with polymaker PLA pro. Modified the STL to remove the rails, optimized the print orientation for larger contact points with the print plate, and reinforced the rear of the lower.
First outing was halfway decent. 3 malfunctions throughout 150 rounds. Thinking it may be magazine related. Magazine follower got stuck and didn’t push the rounds up and and 2 double feed jams. Any tips for the feeding issues? I’m using the curved sten mag that came with the files and Glock 17 extended magazine springs cut to about 3” longer than the magazine.
