Someone recently turned me on to a new weird PETG-GF that is supposed to be very impact resistant and very affordable. I'm always interested in new materials, especially those that are cheap and easy to print in.

I use this "UFA compliant compact striker fired artillery boi" platform for material tests. If it's built well in PLA+, they will take a solid diet of high velocity 22lr with a standard printed breech.

This has been the best one of these I have built so far. I have ran shorts, standard velocity, high velocity, stingers, and interceptors. Extracts flawlessly. No signs of wear at all.

I'll take it out and run the hell out of it within the next couple of weeks.

This thing could probably be a bit more accurate if the rear sights were attached to the barrel instead of the receiver.

Then again, does it even have rifling at all? Maybe accuracy isn't much of a concern.

    It does have rifling, and it doesn't keyhole.

    And you are correct about accuracy in relation with the sight placement. As is, these will get you a 3" group at 20 feet on a good day, which is more than reasonable. I have an 8" pistol that I've hit steel @100 meters with a scope a few times, and the scope is mounted on the barrel.
