    Default One last question..

    Hope i'm not annoying anyone on this board with my novice questions, but after asking tons of various questions on other boards about the Mp5 i think i'm about to understand everything i basically need to know for my first purchase..

    The one last thing i THINK i understand but just a tad bit foggy on is..

    A clip on with the welded shelf RR is the lower part of the gun that's registered ((The plastic housing with the trigger box)), right? Not the stamped sheet metal upper, right? So the part that's registered is the trigger box with a married sear, correct? While the registered part of the double push pin is the stamped sheet metal ((upper)) part with the hole next to the mag well, right? I guess why it's so confusing to me is because they're both called RR's and no one ever specifies if it's the lower part of the RR or the upper stamped sheet metal RR.

    I have no clue why this has been this hardest thing for me to wrap my head around. i know it's simple, but due to other false information from other sites/boards it has set me back a couple steps in trying to understand what i need to know.

    I could be wrong about this and I am sure someone will chime in if I am, but to me a RR is just that a registered receiver. For the trigger pak to be a registered item it would have a serial number engraved on its frame along with its manufacturer at least for all the ones I have seen pictures of. Most registered receivers have the push pin hole for the trigger group; however, there are some that do no have the push pin hole and you can not add one after the fact.

    No annoyance--- ask and know before you buy:

    RR = upper receiver (the part with the serial number, caliber (or not), and date code) with or without barrel
    RTP = trigger pack only (SEF, 0-1-A, etc.)--- situated inside the trigger pack housing
    RTPH = trigger pack housing only

    RR = Registered Receiver = the top part is the MG
    Registered Pack or Sear = the trigger box (or component) is the MG
    Married sear = the trigger component is the MG, but moving it to another firearm would make the rest of the firearm a pistol. And since you can’t make a pistol from a rifle, you must first SBR the non-registered upper to make the registered trigger portable between firearms.

    I appreciate these links. I'll give them a read here in a few.

    So, cutting through all the questions i'll let you guys know what i'm interested in.

    I've been keeping my eyes on this gun for the past few weeks https://dealernfa.com/shop/mp5-doubl...ing-dyer-6728/

    I am aware it's slightly overpriced, however.. i wish for my first machine gun purchase to be a smooth one, so i'm going with a well know dealer.

    I do plan on buying it possibly today or tomorrow. I do like the fact it's a double push pin so i can swap it out with any factory lower vs getting a clipped and pinned modified lower. I wish for it to be as real an authentic as an Mp5 can get.

    P.S: Can someone explain why this one is so expensive? https://dealernfa.com/shop/mp5a2-sh-...-1259-4313738/

    Is it because it's a real german hk94 with a moveable sear?

    A registered sear/box is always more valuable than a registered receiver.

    The first item you posted will always be a 9mm MP5. I guess technically with a lot of money and foolishness you could cut it up and make it into an MP5SD, but that's it.

    You can run a registered sear in an MP5k, MP5 reverse stretch, MP5, MP5/40, MP5SD, HK33/53/93, HK 11/21/51/91 and even stuff that never existed in the HK world, like the PTR32.

    If you are pretty decided on working with Rueben, then I would suggest you look at this:

    https://dealernfa.com/shop/hk-flemin...-h2358-ve2036/

    https://dealernfa.com/shop/hk-g3a2-w...-k899-a025845/

    or

    https://dealernfa.com/shop/hk-g3a3-w...h1418-a033617/

    Then spend an extra few grand on buying an MP5 host.

    Personally, I would go for the HK 53 and use the saved money for that MP5 host. But, granted, the V53 host isn't worth as much as the actual HK91s that are included with the other two. But honestly, a shorty 5.56 is going to be way more fun than a full size G3 in .308.

    mellowb1rd:

    Unless you have won the lottery or something, buying a registered sear and then acquiring various calibered hosts is the way to go these days. Its
    just too expensive to buy RR in all the various HK calibers anymore. Back in the day you could pick up sears up for $500 or less and a RR MP5 was a few thousand.
