    I'm the one that voted "insane". I would recommend NOT building one....

    The HK21/11 series is based on a G3. Think of a G3 with reinforcement plates on the sides. OK. The roller-lock system is prone to wear by peening the inside of the receiver. This causes some slop and can cause issues. IIRC it was to do with lock-up and the inside of the "rails" peening out and causing cycle issues.

    The quick-swap barrels are prohibitively expensive. Was as much as PKM barrels but more difficult to find. If Cal's didn't have it, you couldn't buy it.

    On a positive note, the resale value WILL be maintained! These seem to be popular. Most likely due to the HK quick-change trigger pack that allows you to easily switch to class-3 if/when you get a registered sear.

    I did a great deal of research on these a few years ago and arrived at the conclusion that while a clever design/package, it just wasn't up to par with its bigger cousins.


    Do yourself a favor - spend some quality time with the search tool on HKPRO and (gasp) hk54.com (Todd's board). If you can still dig up those old threads, you'll read what I read about the reliability issues.

    Arguably, it may be a non-issue if you keep the number of rounds you feed it down to a manageable rate.

    I don't know - I'm on the fence. I do think it was mikesmachines or something like that that was making the HK23 (.223 version) around the time the Shrike was going to start shipping () but I stopped looking shortly thereafter.

    Personally I think I'd tackle an RPD before a -21.

    After it comes out of the oven? are you making a gun or an apple pie?
    Or is this something new? like a shake and bake ppsh kit?

    HC, I already have a vector RPD. I can see how the fa version would pound itself apart, but in sa I think the receiver will hold up. one of the appealing points is that it is a small light beltfed. the others, the 34, 42, rpd and 1919 are all big and cumbersome to lug to the range.
    another selling point for me is that it can use mg42 belts or m60 links, I have a loader for the 42 belts and you can get 308 in m60 links from sg.
    and lastly it is a WELD build, my kind of project!!

    With cinnamin sprinkles on top LOL . After me and Stephie ran a few mag's through it , I broke it down , blasted, k-phos'd and sprayed it with KG's ceramic coat. I preheated the hell out of it for the final coat and dusted it on , a real smooth, dull- semi gloss finish . I'll let it bake over night , it can keep the AK's cooking in there company

    Well, OK, you ARE insane, so then go for it!

    I still think these are cost-prohibitive. US parts count is relatively easy on these but also pricey. But it is an HK... think BMW vs. Yugo vs. ??? what does most of Europe drive?

    Wasn't it ORF that re-welded some of the Special Weapons kit built -21s into a more beefy build? That was around the time I was shopping for one and couldn't afford the $3500 or so to get one. Todd at SW about blew a gasket, called ATF, and basically tried to cause all sorts of mischief to shut it down. But I think the ORF kit rebuilds or improvements or whatever they called them were better after the fact.

    I honestly don't know the round threshold to start expecting issues... may be 5k-10k. There may have been some mid-life improvements, but then again HK stopped selling them altogether. Seems FN has the market on current belt fed stuff these days. HK is kinda giving away all their market share and imploding from their own marketing strategy. Hope the XM8 gets back on the table... the G36 can't sustain them forever.

    Is this a Semi or Post Sample?

    If it's a semi PLEASE give some info on the conversion, I got 2 kits and would like to get started on one.

    Oh and I voted to "go for it"

    Here's the .223 version:

    It isn't a true -23, it is mostly US-built parts (like the barrel) and Special Weapons is one of the parts builders. That may or may not be an issue for some people.
