Had to come back and post again.

This is by FAR now one of my favorite firearms of all times.

I have around a hundred - my collection still pales compared to the ones of some of you and yet, I have shot and shoot well.
Went shooting with it today, again, 50 and 100 yards and moving up to 20... it's the best.

So much fun it's hard to describe... it hits. I am not talking about bench rest firing, I am talking about shooting drills and moving around.
This thing is so easy to manipulate and such a tack driver than I'm scoring all hits. My friends are visibly jealous - also because it is easy to do so with it.

Final configuration as well I think - just looks too good like this

What is the favored mount for an RMR on a ‘k’ model?

I am thinking about the M8 offering LINK.  I really like that it keeps the package as small as possible and was thinking I might remove the front sight as it looks like it would leave a nice eotech-ish pattern.  Anyone using one of these?

https://www.ar15.com/media/mediaFiles/77352/44EB5CAF-A0CC-491D-B8CE-7DAD86D37DDD-2603612.jpg

Am I going against the grain here?  It seems like everyone else is going with higher mounts to clear the front ring.  

I am weighing the more comfortable upright shooting position against keeping the small profile I wanted the ‘k’ for in the first place.

passive shooting with nods is my reason for going higher.

I did try the same dot in a low mount to put the dot in the front sight ring but I didnt like how hunched down I had to get to be able to see the dot. It felt un-natural.

FYI anyone looking to stock up on mags.

GunMagWarehouse has most of their MP5 mags on sale, of note:

MKE 30rd. for $39.99

Korean KCI 30rd. for $29.99 (OEM for Zenith mags)

Made a second range trip today. The MKE pic mount is hot fucking garbage. After 150 rounds we finally got a zero when the red dot was moved all the to the rear ( see picture).

The gun itself runs great. Very consistent and smooth. It’s a blast to take to the pistol pit and ring some steel.

I'm glad I avoided that mount. Thanks for the info. I went and ordered the MFI mount. I was trying to find the lowest mount possible and it seemed to fit the bill.

I'm still waiting for my AP5 to show up - it's still in transit somewhere.

The MFI Ultra Low Mount will allow most of the T1-esque mini red dots to co-witness if they're on a low pic mount.

Will give a sight picture like this:

I've had one for a few years (pictured).

ANY stock made for the .22LR will never work on the 9mm HKs or clones. Just won't work, can't even modify it to work, its dimensions are (by design) drastically different so that people couldn't swap stuff between the two.

I know. It bothered me too - this tells you I tried - no way to make it fit.

So I had to go more expensive ways BUT also the well known airsoft collapsing stock that you can find about in this very thread.

Still lots of options, just not that one

I just put 150 rounds of sig 124gr +P through this piece of junk. first mag jammed 3 times, last mag jammed 6 times. H&K 30 rd mags. New copper colored extractor spring. ~800 rounds of MKE 9mm 124gr. I think maybe I'll try the extractor itself next? Maybe ejector?

Edit: this trip out I put the stock end plate back on it.

Are the bolts compatible between the 2 sizes of gun? If so, did you try swapping them to see if it's an issue with anything on the bolt assembly?

Also, mark the mags so you see if any one of them in particular is the problem.
Link Posted: 11/21/2022 11:26:33 PM EDT
[#19]
I'm not sure if the bolts are swappable... I've tried 6 mags, 2 mke, and 4 different HK. it doesn't matter.

Could it be as easy as taking the bolt/recoil spring assembly out of my ap5, into my p?

edit: I did check bolt gap. its right at .013"

I have a similar issue but not as many failures as you. Regular AP5 using MKE mag, Zenith mags, KCI gen 2 mags.  Starts with a failure to eject the brass although the brass made it out of the chamber, just not out of the gun.

After replacing the factory extractor spring with a new MKE one I made it through about 150-180rds then it stared acting up again.

I picked up a HK ejector, HK extractor, HK extractor spring, and a HK trigger housing (hasn't arrived yet). Grabbed the trigger housing because my factory MKE has some holes that look more oval cut than round.

I'll take it out and try again once I get the housing in.

I hope all that crap fixes it. It is the least reliable PCC I own.

I considered it with my standard model but figured I'd throw parts at it a bit and try to fix it myself. I'd be interested in hearing what the resolution is with yours. From the pics you posted, we are having the same failure, you are just having them much more frequently.

Here's my AP5-P. Choate Side-folding stock, MI rail, A3 Tactical forward grip and handstop, Magpul MLOK offset lite mount, Sig Sauer Romeo 5, Modlite PLHv2-16350 light. Not enough rail space to attach a Unity Hot Button, so I will replace the Magpul mount with the Modlite mount that has the integrated Mod button/offset mount and get a Surefire tailcap. I've got 8 30rd MKE mags, 8 30rd HK mags, 2 15rd HK mags, and 2 Magpul drums that I bought when 114 looked like it was going to pass (and did). Waiting on my trigger housing to be machined to MP5K spec from HKParts.net. Might replace the optic mount with a MI or other brand, the MKE one is kind of garbage. I also have a SP5 SBR, and one of the .22lr MP5's that's also a SBR.





EDIT: foregrip is from A3 Tactical, not ACE Tactical

I'm not too much concerned with the coloring as I am the oval holes for the sear catch and ejector axle.

My sear catch pin moves freely up and down in the oval hole. Lots of play.

@LOS

I'm pretty sure it was your picture some many pages back that led me to the A3 Tactical foregrip. I didn't get one for my SP5 because I have the B&T forearm with light on it, but might sell it and go with the MI rail and ModLite setup like I am for the AP5-P.

My MI mount was tight as shit on the gun.

right under  the front "tooth" of the mount (on the gun) there was almost like a little raised portion of the receiver I assume was some kind of bump from the receiver being bent.
Almost didnt get it put on.

I had to remove the other 3 mount brackets and start with that one first and had to use a tiny little punch to tap the bracket in to the right position.
Once that one was in I had to weasel the other front one in too. the two in the rear I was able to slip them in no problem.

Even without the screws threaded in im pretty sure the mount wouldnt come off it was so snug.

looks like you are extracting fine, but not ejecting.

try swapping the ejector.
