| I have seen different trigger groups available in the EE from time to time that are FA parts. Is it legal to put then in a new production semi-auto mp5? I know there are no new machine guns to be made after may 86', but I've heard that certain parts themseves are registered as NFA items and are legal to use in new guns. Are the trigger groups themselves registered as an NFA item or they made and offered to be replacement parts? Is this even true? I wouldn't want to try anything illegal, but if it is ok, they are only like 6-700 bucks the last time i saw them and about 1k for a new gun. It would be an inexpensive way for someone to play with go fast stuff. Any help or guidance is appreciated. |

FA trigger housings will not (they had better not) fit onto SA guns as-issued. You must modify both the outer grip assembly and the inner trigger box which both removes the ability to fire FA and allows the assembly to fit onto a SA gun. And there is no inexpensive way for you or me to play with a FA HK. Dealers/manufacturers, yes. But for you or me the entry price to FA HKs is about $15,000!

Here ya go, this explains all. www.hkpro.com/hkconversions.htm There are pre-86, fully transferable autosear trigger packs out there. Always wanted one because the trigger pack is the same for all the roller locked guns. You could use it in an Mp5 type, then swap the 9mm hammer for a G3 hammer and put it in an HK21E and neither gun would be subject to the BATFE's usual "once a machinegun, always a machinegun" rule. You could have several different guns firing full auto and yet only have to buy one registered sear pack. Unfortunately, I'm not the only person who thinks this is cool. Last time I checked, registered sears were going for nearly ten thousand dollars, not including the cost of a host gun to drop them into. |
Thanks for the answer duke. I thought I saw some in the EE for like 600 bucks, maybe there weren't any guts in them. It is a cool idea. Guess us poor folks gotta stick with bumping off mags  j/k it's all a matter of priorities, I could have one, but I;d have to do w/o some other stuff and I just don't really want one THAT bad.

Well your receiver is finally straight at least. Not sure how Kerry pulled it off but that's done. Now we have a problem with the rear sight block, that is supposed to go around the base of the barrel where it goes into the trunion. It is way too small for the diameter of the barrel and is out of spec compared to other Krink kits we have on hand. We have no spares since those other Krink kits are also waiting to be built, including one poor soul who has been waiting since MAY for his build. We have no tooling to ream the rear sight block out bigger and we don't want to put the barrel in a lathe to make it smaller since that's right where the chamber is. 40,000+ psi has to be withstood every time you pull the trigger so its not an area on the barrel that we want to remove lots of metal from. Here is the part that is out of spec, except this is a full size Bulgarian which is nothing like the one on your Yugo.  K-VAR also has full size Romanians in stock which still doesn't do you any good. Nobody I can find has Yugo Krink parts for sale seperately. So when we figure out how to modify your out of spec rear sight block and actually pin to the barrel correctly, THEN that will "get me moving". I keep telling people, building AKs requires problem solving and problem solving requires time. Its not like an AR15 that goes together like a kiddie lego set. Sorry for the thread hijack, but you asked here so I'm responding here. |
Close. Un-married sears, ones that can be moved in a trigger pack from one gun to a different caliber gun, now go for $12,000-$15,000. |

How the heck could the kit itself be out of spec? The gun was fully assembled by Zastava into a working gun and then cut in half for importation into the US. The sight block was assembled onto the barrel when I sent it to you. I know there are those completely unassembled/undrilled kits out there, but mine wasn't one of them. I thought Armory USA recievers were the best, so that's what I sent you. I hope you have me confused with another person/build. |
Ack, I was. That's what I get for posting at 1am. Had that particular problem on my mind and for some reason thought it was yours. That problem is indeed with one of the unissued "virgin" kits we are building. |
