Running an ETS mag through the KF5. These mags fit very tight, but feed pretty well - I'd say they are the most reliable magazines that aren't the HK or KCI mags. ------------------------------------------------------------------------------------------------------------------------- I'm Ivan - a fella who works to document and record the history and technical background of the development of homemade firearms.

https://utreon.com/c/ivanthetroll/ Just a little announcement and heads up - as Biden increases pressure on homemade guns and YouTube continues to tighten rules, it's only become more apparent that I need a good backup - and I've decided that Utreon is the best solution. I'll continue to post short testing videos on Youtube as long as I can, but certain "more interesting" videos will have to go on Utreon, and the ability to ask specific questions and get specific answers will have to remain there as well. I'm planning on doing Q&As where subscribers can ask questions, focused feedback on troubleshooting, and some other perks for those willing to support me on Utreon - more to come on that. ------------------------------------------------------------------------------------------------------------------------- I'm Ivan - a fella who works to document and record the history and technical background of the development of homemade firearms.

Running a couple mags through the T91 on a UBAR2 printed lower The T91 is an AR-15ish design, very interesting system. My upper took some work to get it running reliably, but it's worked great since. -------------------------------------------------------------------------------------------------------------- I'm Ivan - a fella who works to document and record the history and technical background of the development of homemade firearms.
