HK MP5 Platform (transferable full auto options)

[New Hampshire SMG]

Hello Everyone
I’m looking for some input from the group on the HK MP5 platform. Specifically, the three legal transferable full auto options. From a versatility standpoint, I have for the most part eliminated the registered receiver (#4 Listed). Can anyone on this forum provide any guidance or direct experience with the two options listed below (e.g. Fleming or S&H Sear & registered "trigger box" (push pin swing down receiver). I’m told the registered "trigger box" (swing down) is the closest “full breed” MP5 available on the transferable market. I have also added several links below as a reference. Trying to understand if the registered trigger box option is worth the premium?

1. MP5A3, 4-Position Pack, Fleming Sear, TSC/Fleming/Dyer

2. MP5N, Push Pin / Swing Down Registered Removable (trigger pack)

4. HK MP5A3, Hard Times Armory, Registered Receiver, Dyer

Any input from the group is appreciated.

1 and 3 offer the most options.....as the sear can be used in different HK 9X host guns.

4 is the closest to a "real" MP5.....as it is a registered receiver, double pushpin gun.....and any MP5 trigger group can be used.

2 sounds like a registered pack in a pushpin receiver.....technically not a "kosher" conversion......the pack is "married" to the host receiver......think of it like a registered receiver Uzi conversion with the blocking bar intact and a slotted bolt.

If two is a registered, removable trigger pack, that would be the best.
Who is the trigger pack made by?
DLO?
Neal Smith?
Alltec?

If two is not a registered trigger pack, 1 and 3 will be your best choices

I have registered sears, but if I had a choice to do over again, the box is the best way to go IMHO

 

[New Hampshire SMG]

Thank you Villafuego & Colossians
I will check on the trigger pack manufacturer

I agree with Villafuego on the registered pack in a swing down receiver. It is either married or not quite kosher. My first MG was a Fleming sear. Very versatile and a lot of fun. I wanted a registered receiver for a while just because it is closer to the real thing. But I can’t justify it at today’s prices. The RR will not do anything a seat won’t. And the seat gives me options.

 

[Villafuego]

After looking up #2 on the Autoweapons site, it is listed as a Wilson Arms registered receiver, double pushpin gun....not a conversion sear or pack....

That would make it essentially the same as #4 on your list.....in the somewhat confusing description, they are basically trying to say that a proper RR gun has the ability to accept any unmodified MP5 trigger pack......

My analysis:

>1. MP5A3, 4-Position Pack, Fleming Sear, TSC/Fleming/Dyer
>https://dealernfa.com/shop/mp5a3-4-p...nt-h3218-5921/


Quality dealer, good conversion device, quality gun.
A very good & safe option, but you will pay a premium.


>2. MP5N, Push Pin / Swing Down Registered Removable (trigger pack)
>https://autoweapons.com/photos17/apr/4969mp5.html

It it is a push-pin, then it is married to the gun.
This trigger pack cannot be used with any other guns.
I have not heard any positive things about this dealer.

3. MP5SD3 Fleming Sear / T Dyer
https://autoweapons.com/photos17/may/13431hkmp5sd.html

Quality conversion device, quality gun
IMHO, SD is more of a safe queen type gun (they do look cool).
I have not heard any positive things about this dealer.


4. HK MP5A3, Hard Times Armory, Registered Receiver, Dyer
https://dealernfa.com/shop/hk-mp5a3-...ver-dyer-4758/

Quality dealer, good gun, but it is not a sear, so you won;t be able to use on other guns.


IMHO, of the 4 proposed options, I would say #1 is the only viable option presented.


Couple other notes:

1) If you plan to shoot and want multiple host guns, you want a unmarried conversion device

Reuben has a bunch of other guns worth considering as you are mostly just buying a conversion device:

43K https://dealernfa.com/shop/mp5k-pdw-sh-sear-sef-dyer-excellent-1750-2115443/

Personally, I would go with option #1 and then buy some other host guns as pistols (MP5s etc).

Did a quick search:

Here is another option:

31K - S&H sear https://www.machineguncentral.com/ViewDetails.aspx?p=2308--ba97cca0-00b1-4da8-9d84-ad940a3ecee8
Figure 500 to get this into a SEF or ambi-SEF pack pack or 1K into a 4-position burst pack.
I don't know the seller, but this would be the option I would pursue....

[mattnh]

BTW, as you are new to HKs, be aware that there are some negatives to having your sear in a burst pack
Most people starting out seem to want them, but they are vastly more complex and expensive and SEF packs.

You will NOT be able to assemble/disassemble it yourself (other than swap ejector levers when you switch calibers).

1 & 3 are the best choices. I would not buy 2 or 4. I have Fleming and S&H sear guns, they run fine. My preference is a standard Navy Trigger Group, in other words, I would not buy any of those.

To everyone on this thread.
Thank you for all the insight regarding the HK MP5 line (legal transferable full auto options). I'm always impressed by the professionalism of the Uzi talk forum members. Take care everyone!!

If you are looking for a registered HK sear, watch for 91s and 93s with a sear. I picked up an HK 93 with a Fleming sear on GB a couple of years ago for about $4k below market for just a sear. That left enough money to buy a nice MP5 host.

 

[mattnh]

FWIW, I attended a live auction in Manchester NH about a month ago where
4 transferable sears w/guns each went for <30K (including the 15% buyers premium):

Here are the catalog entries:

https://live.amoskeagauction.com/m/.../563?url=/m/view-auctions/catalog/id/7?page=9
https://live.amoskeagauction.com/m/.../555?url=/m/view-auctions/catalog/id/7?page=9
https://live.amoskeagauction.com/m/.../554?url=/m/view-auctions/catalog/id/7?page=9
https://live.amoskeagauction.com/m/.../556?url=/m/view-auctions/catalog/id/7?page=9

Yep, as suggested above, one of them (a 33) went for 3K less than the MP5s.

Personally, if I was looking to buy a HK sear I would post a WTB ad on the various sites. I have gotten some decent deals. Yes it would be more work and you might have to deal with a scammer or two to be sure that who and what you are dealing with is legitimate. But it is a daunting task to sell a machinegun. The # of "tire kickers" is amazing. They offer all manor of "deals". To sift through all those "offers" and questions takes a fair amount of time. If you present yourself as a qualified buyer with immediate cash that can be tempting to someone who is thinking of selling.

I would also go to the gun clubs here in New Hampshire. Go to the meetings and introduce yourself and let the membership know what you are looking for. This would also give you the opportunity to see and possibly shoot the very high priced item you wish to purchase. Good luck with your search.

For flexibility get either a registered sear ( the form will have the sear as the reg. part- not the receiver) Or a DLO registered pack/frame. Practically speaking you wont be able to tell the difference in shooting them. As in zero. The purists favor the packs. packs run about $2-3k premium over reg sear. There can be issues using a reg pack with burst and some other configs I believe.

First off you kinda need to decide whether you are more of a collector or a shooter. If you are primarily a shooter then get the sear or box. As cheap as you can find them. Then start buying host guns- whether clones (favored to beat up on) or factory guns. The clone host + reg. sear bought from an indiv is the cheapest way to get in.

If you are primarily a collector and will baby your guns and show them off and wall hang them and are a purist then skip the pack or sear and get a double push pin swing down lower reg. rec. gun. Best to buy one of these from a reputable dealer. You will pay a premium.

Note that MG prices and esp. HKs have been soft lately ...so bargain some. Its a buyers market now whereas it usually is a sellers market.

I have the same question as the OP. Is there a book or other definitive description of these differences?
