If I were to get the 22lr conversion kit would I need a different barrel? Don't laugh,I really don't know.

You can do it either way. My KPF upper has a real .22lr 1-16 twist barrel, but on my MG I just use a cheap Model 1 .223/5.56 1-9 twist barrel. The KPF upper is very accurate so I don't use it for full auto, just target shooting. The Model 1 upper I use on my MG is much less accurate, but who cares. It's just for bullet squirting. When I say my .223/5.56 barrel is much less accurate, I mean my groups are almost twice as large at 50 yards. It's no big deal though. You can still kill a pop bottle with either one. If you buy a Ciener kit, you can use the .223/5.56 barrel that's on your rifle now. It will work. |

You can use your existing barrel. It isnt ideal for best accuracy, but will do fine for plinking at 25-50 yards. The M261 manual recommends shooting a magazine of .223 every 400 rounds of .22lr to keep the gas tube clear, IIRC. Most people think this is overkill. I just run 5 rounds or so through the upper at the end of a shooting session. |
