Hopefully others will find this helpful if they run into the same issue.
So I recently just finished my first ar pistol in 9mm. I've always loved and wanted the mp5 but they, and their 9mm variants are usually far too expensive for my taste, and the .22s, though fun, just don't have the umph I'd like it too have and the one I did have was way too unreliable to ever really enjoy.
Anyways, for my build I decided to use the RRA pistol buffer tube which would be mated to my new frontier armory glock 9mm lower. And for the end plate I used the Odin works with the dual sling loops. When mocking up the lower I found that the buffer tube was tight before it was able to engage/hold the buffer retaining pin. A small annoyance that could be left alone, sure, but over time i know a day would come when I would forget the pin isn't there and I would open up the pistol and have a 7.5oz buffer headed toward my face.
As you can see the Odin works end plate is rather thick, but even with a regular end plate it would still barely be over the pin, not enough for me to trust it. Plus I really liked and wanted to use the Odin works plate.
I had a cheap out of spec carbine tube laying around and figured I could cut off just the end with enough thread to hold in the pin and still fit between the buffer tube and allow the upper to close still. So I took the old buffer to a band saw and cut off the end with about two rows of thread giving me enough to sand down and adjust as necessary.
Once in place I installed the tube to see where I was. First fitment the buffer tube couldn't thread in quite all the way before hitting the ring. Since the pin was already sitting pretty deep into the retainer, I thought it would be better to sand out the retaining pocket on the ring a little deeper and spin the ring out one more rotation, then sand the front of the ring so it would sit flush with the ear of the lower and allow the upper to pin in.
Their may have been easier fixes for this but hey it worked! Cutting, fitting and sanding maybe took me 30min to get it to fit perfect.
The end result!
