R51 General Discussion / UpLULA mag loader
May 11, 2017, 05:30:32 PM
Most people probably either have one or know about the UpLULA mag loader. It works fine with the R51 mags. However if you have a 1911 mag adapter (I believe it comes as a set of two) you can modify one to make the opening a little wider, and then the loader works even better with the R51 mags.

I will try to give the short version. I have shot several thousand rounds through my R51 without issue. The other day I had a round fail to go into battery by about 1/3" and it jammed up the slide. I could not pull the slide back no matter how hard I tried. I had no choice but to force the slide the rest of the way forward into battery (after I ensured there was not a squib hanging things up), and I was able to fire the round. That was not my ideal solution, but I really had no choice.

After I got the case out, it looked like this. Obviously it had been folded over which caused the failure to go into battery and caused it to get wedged in the chamber. And I'm sure that forcing it the rest of the way just made it worse. I normally do my own reloading, but I was shooting some left over Freedom Munitions ammo that I had. I have shot thousands of rounds of it without issue. But they are reloads, so you never know.

I am not totally sure how this had happened, but speculation was that the case mouth somehow got hung up on the barrel chamber and caused it to start to fold over and my forcing it the rest of the way made it worse. Note how the spot with the arrow looks like it got hung up on something.






At first I did not think that the barrel was the cause as the barrel chamber is beveled. Until I looked a little closer and saw that where the bevel and the feed ramp meet, there is a pretty sharp "point" where the arrow is in this picture (on both sided of the chamber). It is possible that the case mouth may have been a little too flared to begin with, and caught on one of those sharp edges.

I rounded those sharp points just a little bit, and polished it up (bottom part of the picture), and that should prevent this from happening again. It's barely noticeable in the picture, but it no longer has a sharp pointy spot. This was mostly an ammo issue, but the barrel probably contributed to it. So, while this is probably an isolated incident, you may want to take a look at your barrel and see if it has that sharp point where the bevel and feed ramp meet. it does not take much to round it just a bit.

R51 General Discussion / Racking with a full mag
December 25, 2016, 11:09:47 AM
I have read where people have complained about having problems racking the R51 with a full mag. I too initially had the same problem. However after keeping the mags fully loaded for about a week so the mag springs can take a set, and running several hundred rounds through the gun, I no longer have a problem. I have done no modifications to the mag. Here is a short video where I demonstrate racking the gun with 7 rounds in it.

Introductions section / New member from Texas

Hello everyone. Not a new gun owner, but a new R51 owner. I had always wanted one since they were first introduced, but just recently finally bought one.
