i picked up one of the rebuilt us airforce kits from the ee several months back and have managed to acquire a few extra mags for it. honestly, i havent shot it yet. id just as soon use a 22 rifle. however, i thought the conversion might be a useful shtf item.

Pick it up! I really enjoy my .22 conversion kit and it has a permanent place in my range box. Great for training with the AR on indoor ranges, or for shooting the Newbold 'Hang Tuff' targets outdoors.
$100 is a very good price for one of these kits - it should come with a magazine or two (my Oly .22 Conv kit came with one magazine and cost $99 - its a copy of the US Army conversion kit). I prefer the US Army style over the Cienner version as the Military one allows you to practice using your full size magazines (with a .22 conversion insert). I have not tried the Air Force version so I can't comment on it. The rifle works really well for training at 50 feet (indoors) or up to 25 yards. the 1:12 rifling twist rate is best - but I find 1:9 to adequate to 25 yards. |

Well, I hate the white mags, but the AF unit does what the others don't. It holds the bolt back after the last round is fired. Also, the "barrel" portion ahead of the chamber has very shallow rifling; just enough to get the bullet started spinning and still allow it to engage the fully cut rifling of the barrel without deforming. Haven't yet tried it in my new M4gery w/ 1in9 twist, but it's always been very accurate in the 1in12 preban barrels.
I keep threatening to paint the mags black, but never seem to get around to it [:D] |

Good luck with your 1 in 9 M4gery. .22 cal. are generally fired in a 1 in 16 twist barrel. A lot of people have had a lot of trouble with severe leading in 1 in 7 barrels.
There was a company with a double barrelled English sounding name that was planning to offer .22 cal. dedicated uppers (perfect M4gery on the outside). Don't know if they're still around. |

Leitner-Wise Rifle Company. I think they must be having production problems, but according to the website they're still in business. I got an email from their sales guy last week about a couple .22 uppers I'm supposed to be getting and he said there's a "delay", but that they're still planning on shipping them.
Compass Lake also makes a dedicated .22 upper. Personally, I'd rather get a dedicated upper and not lead up my barrel. |

Have never had any appreciable leading using my unit in a 1in12 barrel, and at one point fired between 1500 and 2000 rounds thru it w/o either cleaning or firing any .223. Oddly enough, when I did go back to center fire, I started having failures to eject, and assumed that lead had piled up in the gas port. Tore everything apart, even replaced the gas tube, cleaned the hell out of the gun with no success. Put the gun up for 7years, and it wasn't til I got to this website, and read about the extractor spring problem, that I finally got the piece working again. It never was any lead fouling causing a problem. [:D] Guess I'll find out about accuracy w/a 1in9 twist this Saturday.
