I had three mp5s that were all pre may.  I could have kept them but sold them off before I gave up the FFL.  I'm glad they are gone.  They were fun to shoot but frt can replicate FA fire.  Believe it or not, it gets old shooting FA.

Why? This one is basically factory config and can run any trigger group you want?

Swapping it to a decent host that's not a 9mm? Belt fed 21 ?

I was an FFL holder and paid the SOT.  I had more guns than that. Here is a pic of an HK53 and an MP5.

Personally I prefer using a factory sear group vs a "depends who made it" sear trip lever.

Qualified is good to go but Hard Times Armory was a stamped steel one leg trip lever that will eventually break.

If I didn't already have a transferable sear pack I would just get an FRT for the HK roller delayed guns.  FRTs are going to gut the shooter grade transferable market unless they get banned.  I was about to pull the trigger on a converted AK in the $40k range and instead put an FRT in one of my semi autos.  It's not exactly the same as real full auto but close enough that I no longer want a converted transferable.

Collectible machineguns like my Type 96 lmg won't be affected by FRTs.

If you are buying a registered sear or registered frame you do need to do your homework to make sure you understand what you are getting.

The Fleming "H" and Qualified "K" series of sears are IMHO the best of the bunch.  They were both made on the same Fleming owned stamping dies via the same process and essentially identical.  I own three of them and they all have a huge number of rounds through them and all basically look new when you clean them.

Below the Fleming H and Qualified K series are the S&H sears.   They work well and are mechanically identical to the Fleming/Qualified sears but are cast and a bit more "rough".  The material around the pivot pin holes also isn't robust based off the ones I have personally worked on and the ledge on the sear were the hammer engages can round over since they are generally softer material being cast vs. stamped steel.

The rest of the registered sears are definitely a mixed bag and you need to really understand what you are buying.  Same with the registered frames as some of them are not being full auto spec and having proprietary parts in them.

For most owners a Fleming, Qualified or S&H sear or a DLO registered frame is going to over a lifetime of enjoyment across every host type in the HK lineup for not much more money than a MP5 registered receiver push pin conversion.  

This particular gun being sold by AIM the conversion looks well done and my best guess is probably a Billistics conversion.  If you want a  registered received push pin MP5 this one looks nice and the price isn't bad.  I suspect it will probably get bought by somebody in the near future now that its confirmed to be push pin vs. clip on conversion.  Personally if it were me I would spend maybe another ~$15K more and get a former pre-may flipped to transferable factory MP5.

Very nice.  Do you know who did the conversion?  It will be on the owners Form 4 as the manufacturer.

I’d rather buy this than a Ford Ranger Raptor.
