I know there’s a lot of hate but damn my Scorpion EVO is fun. Part of that is probably because I bought it when they were really cheap, to be fair.

I enjoy my MPX.  It’s a two-stamp with a dedicated 9K.  

My brother uses a JP Enterprise 9mm that uses Colt mags and it’s pretty fun too.

I am hoping to get my YHM R9 soon and put it on a PSA ARV, so hopefully it's that combo!

PSA ARV + Arizona Regulator + Maxim Defense roller delayed buffer + suppressor of your choice

Highly recommended

Still need to try a CMMG 9mm setup like @Amphibian has, and a Stribog A3 (but I've read its roller-delay impulse isn't as smooth as an MP5).

I'm impressed you recognized the old girl!

Always wanted a TMP - now it just needs an FRT...  The folding stock adapter was a lucky interaction with a guy online who was similarly TMP-crazy I guess and who had the wherewithal to make them happen!  Eventually I "had" to get the TP9 shroud and can.  I toyed with buying a B&T but since I had the SPP and kinda wanted the "original" it just evolved  I have the TMP fixed stock but the folding one is so much better that I never use the real deal.

After getting into MP5 platform (Cool... but $$$$, non-ergo, clunky, and finicky) low key wish I would have just switched the Scorpion over to the Nexus parts and rolled that way.


AR-9 with a properly sorted roller delayed buffer setup absolutely hammers for the cost to fun ratio - I think I'm in ~25% of what the MP5 was so far and it eats whatever I feed it and just chugs along.

I agree on the 'roller' the Stribog A3 not being as smooth even with the optional 'blocks' you can get.  Same goes for a STOCK CMMG.  A stock CMMG isn't that smooth and CMMG doesn't offer different bolts with different angles to control the delay in the same caliber...but since it uses the buffer tube and the tail of the carrier is standard then the tuning options are limitless.  

I have full auto MP5's as well and use them occasionally.  My tuned CMMG's are my goto especially for SMG matches.  The MP5 shoots too fast for the SMG matches I go to.  I want around 600 RPM and the MP5 even with a different locking piece isn't going to run that slow.

Myself and a few others on Reddit have been tinkering with the CMMG RDB system in conjunction with using strong magnets to induce Eddy currents with the aluminum buffer tube: https://c3junkie.com/?page_id=4254

I don't like it to run this slow but this just shows you the extremes that you can tune it:
Slow Cyclic rate testing with 9mm CMMG RDB and Eddy currents







Pictures below need to be taken in context of other tests documented on my website above.  There are some people running these with no buffer at all.  Just some magnets.  Super smooth but IMHO, not enough delay which results in broken hammer/trigger pins and some gouging of the cam relief area in the upper.  The configuration I have pictured below uses the KAK DBC sliding carrier weight.  Adding that removed trigger slap.  Then the 25lb wave compression spring with opposing spacers prevents the wave spring from going solid height as well as allowing the magnet to also have some dead blow affect.  With no traditional buffer, this setup has low reciprocating mass but we are adding mass to the carrier with the DBC but the total mass is still less than a typical setup.  This is all a work in progress.  I plan on running a few thousand rounds of suppressed full auto with the two configurations below and see how they hold up.  

If you want something more tried and true then look at my ARS setup which also works for 556.  Documented here: https://c3junkie.com/?page_id=2757

Unless you get a Maxim buffer it's going to be loud.

Presently, my go to 9mm carbine is a PSA PG-9. It's pretty slick. This week I should be picking up my first MP5 clone. Then hopefully before Christmas I can get my hands on an ARHK FRT.
