There’s been problems reports of it in the past. But a few guys here are reporting that it’s trouble free. Some guys here even have stated that it’s their agencies duty round.
I shoot PRVI M193 in my 1/7 with no problems. Prvi also makes an M855 spec load if you want to stick with 5.56 pressure in a 62 grain. Otherwise Winchester is a good source for milspec M193/M855. Beyond that I think most other manufacturers loads are .223 pressure.
I found a whole bunch of it for $3.50-$4/ box a while back so that is why I like it.:o And it runs fine in my guns. I believe Q3131 is the Federal Bureau of Prisons duty round. I have no idea why they didn’t just use Lake City M193.
Federal XM193 is good ammo. I just finished firing about 1300 rounds of it through my 6920 at a Gunsite carbine class. No malfunctions and good accuracy. I plan to get some additional cases of it soon!
You heard right, the BOP uses Q3131. It works for us. When we got it a couple years ago, it replaced Federal Eagle .223 55gr., we had several misfires with it during Annual Training. It was enough that my buddy who is one of our Firearms Instructors mentioned it to me. One of the issues turned out to be the rifle, not the ammo, but I can’t remember what was wrong with it. We have M16A1s, M16A2s, and M16A2 Carbines (pre M4s with A1 uppers). All are Colts but there are a couple Vietnam era Harrington and Richardson M16A1s, very cool, didn’t know they even made those.
