I hear we like MP5's around here. This is my MP5-N with the F stock instead of the original 2 position A3, that one is rather brittle as this started its life as a parts kit and it was old. Don't particularly like to abuse it if I don't have to. Original barrel and majority of components, has around 23~26,000 rounds on it at this point and still going strong! Only general wear and tear on the usual components like the extractor spring and roller retainers, etc. I do have the original trilug flash hider as well that came attached (more like stuck) to the barrel, which is nifty. Original sling as well, though I cant stand the thing. Handguard was missing from the parts kit, so modern surefire handguard was thrown on.

This gun always makes people come over and ask if they can have a go with it haha.

I'm sure my significant other would have probably chosen a new car over this project but... you only live once right? 😅

Bought a cheap mp5 clone,
Was wondering if these tooling marks are to be expected? Thanks

Hello r/mp5 - here is my conventionally barreled and suppressed mp5.

The next time you see me will be the real, true, SCHALLDAMPFER.

My next set of these will be my real true, honest to goodness mp5sd. Good lord know I’m excited!!!

This mp5 is just boringly reliable, consistent, and just easy as can be to shoot. It’s basically a cheat code.

Milkman, 90 degree locking piece, HSL 147.

I left a clip of supers in at the end as these are the first ever shots on this new, second Polymer Pew metal lower. Breaking this new lower in for SchallDampfer.

Good times!

Century arms AP5 bought used, G3 converted lower housing, MI handguard with some busted KAC rails I had lying around, primary arms 1x prism on a BT-21298 rail from an older project, and a CNC warrior tubular aluminum brace on an MI 1913 end cap.

Just kind of a mess of parts, but it's my mess of parts. Hoping to turn it into a little FRT host for funsies with a cheap can.

Just added the Shadow Strategic optic adapter to the KAC Tri-Rail & loving how I can now use the diopter sights as backups.

MKE AP5-P with RCM MP5-E bolt, RCM 80 degree locking piece, MKE ejector and RB trigger pack.

Looks like the bolt gets caught on the ejector.

Just installed the bolt and locking piece. Haven’t fired the weapon. Cycled fine the first 10+ times then this started happening.

Any suggestions would be appreciate.

Just bit the bullet and got an SP5K-PDW with plans to suppress, FRT, SBR, the works. My main question lies within the suppressor choice. I've been pretty heavily leaning towards the Lithium 9 but have heard it's quite gassy especially if you're running it in fun mode with an FRT. Can anyone confirm or deny if I'll get gassed out?

So ive had roughly 500 124gr down the pipe, having the sb brace issue so i plan in dremmeling that tonite. But no matter what end cap/brace/whatever i run, i get these what appear to be brass shavings. Runs excellent with reg end cap. Is this still 'breaking' in ya think?

Other than a red dot ofc

I have a 5.56 rifle but looking to get either a .300 SBR or an AP5-P. I read the AP5-P needs a new extractor spring every 500 rounds is that true? That would make the .300 blackout the easier choice…but the AP5-P is so sexy…How reliable is this gun if you put in the 90 degree locking piece?

Looking for a home defense gun. The .300 blackout is nice because it could be used for the occasional hog hunt. I also have a stripped aero lower which I could build it on.

Hello guys, recently bought and AP5, and I’m wanting to add an optic. What should I be looking for, and what is best practical?

-absolute co-witness
-1/3 co-witness
-tall mount

I’m finding the iron sights to be a bit difficult to use. With that being said, practice makes perfect, and I’m definitely planning on mastering over time.

I guess my question is, what are the pros and cons of the 3 options above.

Just trying to learn more,

Thanks

I’ve never shot a suppressor, let alone owned one, but always planned on getting one someday for my MKE AP5. Given the state of things, now seems like a great time to jump in.

My budget is $600-1000 and I’m usually looking for the best bang for my buck (if the AP5 didn’t clue you in already). Priorities, in order, would be long term durability (would like it to last as long as the barrel if possible), minimizing gas blowback, DRIP, and then weight and length. Not a huge concern around noise as I don’t plan on shooting subs often, and always using ear pro. That said, quieter is better of course.

I don’t know much about hubs and attaching suppressors, so help there would also be appreciated. My AP5 has the tri lugs and the barrel is threaded. I’d anticipate the can living on this long term. I also have a Stribog SP9A1 that I wouldn’t mind trying it out on, but either way I want the focus to be on the best way to attach to the AP5.

What should I get and why?

Just received an AP5 SD that was converted to be a true SD. It looks like the barrel is properly ported to my eye, but I was surprised at how loud 124 grain ammo was. I can’t tell if I’m hearing the supersonic crack or gas ejecting from the port. I think I was foolishly expecting a Hollywood quiet type sound, but it was pretty loud. does anyone have any experience with these? Are they supposed to be hearing safe? or comfortable to shoot without hearing protection? What can I do to make it quieter?

Edit: seems like my k can size is part of the issue. Please dump recommendations on which can I should try! Thanks!

Title says it all. I am looking for a folding stock for an mp5k that fits via 1913 rail on the back. I want something that wont interefere with firing when folding and also locks up rock solid when unfolded. Bonus points for a cheek riser. TIA.

Got a replica okp7 optic and a YHM r9 suppressor... my first Can btw and I've got the tri lug mount too

I’ve been looking for a couple days and I can’t find any place online that has a black A2 stock in stock. Does anyone know where I can get one?

No threads? So I just received my RD3 Ambi and the right side switch was missing the set screw, but appears that it is also not threaded for one. I can't feel any threads when I run the allen wrench across the inside of the hole. I will be reaching out to CS but just wondering if I'm going to need to ask for a new switch as well and not just the set screw.

I want to convert my safety harbor KES. However their conversion kit seems always out of stock and I can’t contact them. Anyone know if these are ever in stock or if there are alternatives to convert my KES to a stock

I know the phrase just because we can doesn’t mean we should but, I’ve been really wanting to find a home for my Surefire M900. It’s dated (updated lumen factory head though) but it’s such a neat piece of kit I want it in use somewhere. I have the Custom Smith A2 stock in the mail and I refresh the KES page from Safety Harbor daily. I’ve been collecting all sorts of parts for these things, it’s incredible how modular they are. The rail on this is the Lee Sporting + 1. The MI optic rail doesn’t fit super good on this and I think the weight of the grip and the heat of the suppressor could potentially warp the polymer Lee rail so I’ve been considering the UTG monolithic suppressor set up when it gets released. I wish it had a round profile instead of the bell shape but it could work out well. In any case these things are super fun and I love seeing what everyone is doing to theirs.

For reference if anyone needs info:

Lee Sporting K+1 rail

I have an AP5 with a typical 2 position SEF trigger housing. I noticed a lot of people recommending the Magpul ESK as an upgrade both for the extended safety, and a smoother safety. However, I've also been seeing a lot of posts mentioning the Magpul ESK will eat away the polymer on the trigger housing and eventually ruin it with enough use. Are there any better options for an extended and preferably less stiff safety to upgrade with?

Size 8.5 feet. M31.

PTR’s build quality seems hella nice, feels leagues above the import clones I was finger blasting.

Does the magpul lower only work with the SEF trigger packs? TIA

So i recently bought an ap5-sd and will be putting a spectre 9 with tri lug on for the time being. Till I convert it or buy a better can. What ive read of you tri lug you want to add a thread protector on thats rockset. My question is there a way to take that off? Seems like it would be pretty difficult. My ffl was trying a suppressor on direct thread and the adapter got stuck and we pretty much had to rockset it to the can to back it off. So that has me thinking ahead a bit. Thanks for any feedback

Just a little backstory. I purchased a Hk A3 stock years ago from Hk parts (I know, I know) when there was literally nothing (including mke A3 stocks) available. I paid right at $1k and was always so mad at myself that I paid $1k for a Hk stock to put on my SP5. What made me more angry was the shiny, easily scratched, not matching finish on the German Hk stock (especially for the price). Well ChatGPT told me some grey SOS pad with gun oil as a lubricant would do the trick to take off the gloss, and guess what!? It’s almost a perfect match to my SP5 more matte finish Hk uses AND it got rid of most the scratches. I was so concerned with messing with a $1k stock but I’m so happy it turned out so good!!! Thank you ChatGPT! I guess taking over the world won’t be so bad if you’re that helpful lol. If you’re looking at how to make your finish more matte, the grey SOS pad and some gun oil as lubricant does an amazing job!
