    the 2 factory kits were iffy that i shot. Maybe ran 80%. They are also pricey when you could find them. Never shot a Fleming kit, but I have not heard good things.

    I owned a Fleming conversion back in the early '90s. Didn't run for crap in a Vollmer conversion or Dealer Sample MP5. The machined steel mags were rough and very inconsistent.

    Build a kit and mags that work and I am in for one!

    H&K introduced a.22LR conversion kit for the MP5 in 1970. This unit consists of a barrel insert, two 20-round magazines with plastic collars and a bolt group which replaces the MP5's single-coil recoil spring with two nested-coil springs. This latter modification reduces the cyclic rate to 650 rpm. But unfortunately the MP5 conversion kit is prone to continual stoppages. With every two or three magazines, an empty case will fail to extract and the bolt will travel rearward and then forward, stripping a another round from the magazine and attempting to chamber it. Sometimes this stoppage is easy to clear, but all too often the empty case or loaded cartridge will either wedge into some inconvenient location in the bolt group or drop down into the trigger group, requiring dis-assembly of the weapon.

    As the MP5 .22LR conversion kits never performed in a totally satisfactory manner, series production ceased after no more than 300-400 were manufactured. Until five years ago, these kits were rarely, if ever, seen in the United States. In November 1987, 137 of these MP5 subcaliber conversion kits were obtained from a West German police agency and imported to the United States. They are of value to collectors only. All .22LR rimfire ammunition produces excessive fouling. In general, conversion kits of this type, designed for low-cost training, operate with only marginal reliability in selective-fire weapons.

    Fleming kits show up for sale every now and then, the last one I saw went for $600. The problem has always been the mags though.

    If there was a reliable MP5 .22 kit, there'd be a huge market for them. You might want to try hkpro.com. Lots of good info on that site.

    Here's some threads on the .22 kits:

    Here's a cache of Fleming's old site:

    Todd Bailey is supposed to be releasing a CA53AR 22lr. It will be a dedicated .22lr barreled receiver that will look like a HK53. I'm waiting on my CA53AR which will use AR-15/M16 mags but is a 53 delayed roller blow back firearm. Supposedly once those guns are released Todd will make a .22lr version that will use Ciener or Black Dog .22lr mags.

    The barreled receiver is supposed to be around $500. All it will be lacking is a trigger group to be a pistol. It is supposed to be sear compatible for full auto use. If it runs it should be a lot less money than a 51 clone with a modified G-3 kit. Time will tell. I'm on the list of interested buyers.

    Supposedly a limited run if it ever happens (apparently it's already been years). To be sold without a lower or paint:

    Todd Bailey.
    You have got to be kidding.
    Are you guys not aware of who Todd is?
    Do a search on google "todd bailey special weapons" before you speak of this person.

    I have to be honest.... I had a problem with the finish on my SD and he said send it back and he will fix it.
    He can be a little rough, but so far he has been honest and helpful.

    Oh, and I might be interested in a 22 kit for it.

    I had two (2) of the Fleming MP5 .22lr conversion kits; one ran well, while the other did not. I sold the one which did not work well to a tinkerer, who knew it was problematic but wanted it nonetheless. I kept the other one, but now I'm interested in selling it. I think Chili17 has seen my Fleming kit at one of his subgun matches in Sanger. Anyway, BlackDogMachine, if you're looking for a Fleming kit to experiment and tinker with so you can develop mags or whatever, then I'd be glad to send you mine as a loaner...

    I'd be interested in selling it and/or trading for some mags... I have a Norrell 10/22 and could use some of your new drums, as well as some Tommy Gun mags for the new rimfire conversion!
