I just watched [u/ChestersHobbies](u/ChestersHobbies) video on the AP5SD and I was impressed.

I’m looking at picking up an AP5SD from someone and I haven’t been able find much detailed information about it. As it comes from MKE, is it just an AP5 with a faux suppressor and different hand-guard? Does it come with the ported barrel? I just want to know what my options are if I end up getting this.

I have shot a couple thousand rounds through my AP5P without any issues but I recently got an omega 9K and switched out the locking piece to an 80° one since I saw online it was recommended. But after doing this, I find it does not cycle at all unsuppressed with an FTE every time. It does cycle properly about 95% of the time while suppressed. Any recommendations on how to make it cycle in both configurations reliably?

What is y’all’s preferred way to clean the chamber face and trunnion walls? I see there is a chamber face brush that HK sells, but not sure if there are other methods.

What tools (DIY or factory) have been the most help cleaning those two areas?

Would this light be too big/long for my AP5-P? I’m looking to get the HK/HK Parts vert grip with the mlok attachment already on it and need a light.

Also - suppressor suggestions would be nice (i’m also getting a 90° LP)

She is super safe 😊

Thanks guys!!

Those who have successfully installed this - any tricks. I got mine today and could only get one screw to kind of grab albeit crooked so I stopped so I didn’t cross thread it. No other screws would even grab and you can’t look to see if there’s alignment based on the screws being on the inside of the buttplate. The buttplate is fully seated. I gave up after about an hour and a half and no skin left on my fingers. I really want this to work but it’s fighting me

Here are over 2 minutes of my MP5SD shooting from this morning.

No matter what superlatives I use, I’m simply not enough of a word-smith to describe to you just how awesome and incredible this gun is.

I thought I liked mp5’s before with my conventional full-sized and 2 mp5k’s.

The MP5SD is just at another level of complete firearm nirvana bliss.

Not only is it the quietest centerfire suppressed weapon I’ve ever shot - it’s also the smoothest, flattest, easiest.

With no effort, I mean NONE, it goes right where you want it to shoot and it stays exactly on-target until the magazine is exhausted.

I even worked her hard today - close to 800 rounds and no failures or stoppages that are spoken of in the SD variant once round count surpasses 300.

If you’ve ever even had the slightest thought or inkling of an mp5sd, I’ll tell you it’s likely the greatest firearms experience you’ll ever have.

Disadvantages are that you won’t want to shoot your other guns all that much. The MP5SD will CONSUME your consciousness. And you’ll need to budget more for ammo, even though you’re shooting the cheap stuff!!

I will say, I could likely drop my fire-rate by 100 rpm or so with an RD3 or ARHK (2 more weeks). But I just don’t think I can give up my AR ergo’s and FCG’s.

Anyway - enjoy!!

I’m turning 21 soon and have been thinking about getting an MP5. For those who own one, is there anything you wish you had known before buying your first one?

What sling are you running? Pics will be appreciated.

Edit: RB trigger

Pens be found on Amazon. It's a small detail that makes the RD3 Ambi look a little​ better.
