AC-Unity Magazines

Is it pretty common for the AC-Unity mags and possibly other poly/plastic magazines to fit tight? Or do I need to start lifting?

Problem with my ZF5p Suppressed

I’ve read several posts and comments, but am still looking for some help. My ZF5p is past the break in period. It runs fine unsuppressed (124 grain). It is still factory, except it has a stock on it. I used my RS9 suppressor and it worked on and off (147 and 124 grain round nose). I had FTE / FTF just about every mag (I was using HK mags). I had some really interestng jams. Where should I start to fix this? 80 degree locking piece? New ejector and extractor? Or all of the above?

Well it happened! Time to chase the rabbit down the hole.

First time owner of a MP5 (clone) PTR-9C. What’s next ? Any suggestions? What’s a good set up ? Thanks for any help.

The most upvoted configuration for Spec it out Sunday was the A2 and 628 combo pack. It's an icon and total classic.

How much play and alignment rod centricity?

After the arduous 3 day wait, I got to bring the can home (haha, first can was just shy of a year wait). How much play should the tri lug mount have? Got a 9mm alignment rod, depending on which lug hole is up gives different centricity, should I worry? I assume I should run the can in the short configuration.

Two extractor springs bent in two days (shoot only 200rds total). How slim of a chance that is? What's going on with my AP5??

Edit: Ok it’s most likely the mags. Went back to range AGAIN and dumped 200 rds using MKE mag with and without suppressor and had zero failure.

Original post: I posted a video yesterday that my extractor spring was bent after a couple FTEs. Replaced the spring, went to the range today and shot about 100rds with suppressor and had another FTE. After clearing the malfunction, I found the new spring was bent again... Is my luck really that bad, or is it something else going on with my AP5???

My AP5 has been having FTF issues since I bought it about two years ago, but I haven't had this spring bending issue before. I recently switched from the Overwatch Precision MOD1 mags to the new MOD2 mags. Could mags be the reason?

Which mount style for tri lug SP5?

I don’t really know what I need for this suppressor but think I want this model.

I have a HK SP5, picked up this week. Which mount style do I need and do I need to pick up anything else like to mount this suppressor to my tri-lug?

Thank you in advance and I apologize for such a stupid question.

Failure to Feed

So long story short I recently got a PTR 9CT and it was working great. Broken in no issues. Multiple grains, multiple brands, even steel ammo worked great. Almost about 1k rounds. Now it jams every mag.

The only thing switched out was the end cap for a brace and added a red dot. But now there seems to be a FTF every mag. I know the stock ets mags are doo doo but is this common?

When I clear the chamber theres 2 rounds that come out, and both of them are dented by the case, but then I put them back in the mag and they sill work. Is it the extractor, is it the mags, is it the dot?(lol) Any guidance is appreciated. :’)

Odd wear spot on bolt carrier

Took my PTR 9CT on the range and I work at an FFL where we have a full auto lower and after running about 100 rounds I took it apart to give a quick clean and noticed this area of wear. For starters I’m new to MP5 style guns so I’m not quite sure if this is normal wear or not.

What subsonic ammo have you all found to work/sound the best in your MP5s with suppressors?

Got an MP5K clone in MP5K-PDW format with 80⁰ locking piece, sporting an Omega 9K on 3-lug. Wondering what brands and types of subs you all are finding sound the best and work the best out of your setups?

I usually run Federal Syntech 150gr, but I'm running low, so I'm looking at other options to try out if something better is out there.

MP5 22lr trigger housing?

Has anyone found an alternative lower/trigger assembly housing that supports G3 grips?

Similar to this, which you could cut the tail and fit it.

Someone else mentioned changing the tail. Can this be done?

Ammo recommendations for 22LR

Ive been looking on Ammoseek.com and am unsure of what to get, I’m between Aguila and CCI, and don’t know what grain is best.

I’d just be doing some plinking, send suggestions.

Surefire 628 vs 328

Going between these two weapon lights for my AP5. Is one preferred to the other? Why or why not?

Thanks so much for this! Super excited to get into this platform.

Magpul ESK selector on Century Arms AP5s

Anyone have issues after adding an ESK to their Century Arms AP5s? I was told by Magpul c.s. that it won't work but have seen/read some posts with them on.

Not sure if the extractor spring failed before the FTE or the case that failed to eject hit the extractor at a right angle and bent the spring, but RIP extractor spring…

Car Trunk Layout

May I see pictures of y’all’s case layouts?

I am building a little British roadster (1972 Triumph TR6) right now and will be removing the spare tire from the wheel well.

I would like to create a case of sorts of that space for an AP5.

Why? Because it would be cool.

Could y’all please post your gun case (foam) layouts for me so I can get an idea?

Thanks!

MP5 builders in Houston?

Visited a few gunsmiths and they don't know who to refer me to. All I need is someone with a bending jig; the rest of the work can be done myself. Suggestions much appreciated!

Solid Customer Service - SB Tactical

Hope this isn’t breaking any form rules but I want to let folks know about a great experience I just had with SB Tatical and a Brace I ordered. Long story short, I ordered the wrong brace for my daughter’s MP5-22 trainer. Sent SB Tactical an email to get a return number and they responded immediately. They offered to swap it out for the correct model or refund no questions asked. I order a lot of gun parts and accessories from many different companies and SB Tactical has one of the best customer services departments I have dealt with. Makes it easy to spend money with a good company.

Anyone know where to find HK 30rd mag that is pinned to 10rd?

For WA…The 10rd mags are just too goofy looking for me.

Largest light you can run on an MP5k

So I currently have an M300c from Surefire. I recently got a new handguard with a beefy pic rail on the right side. I’d really like to put the most powerful light I can on this thing. I’m running an Omega 9k so I don’t think a large light will be as off putting since the larger suppressor will balance out the large light aesthetics wise. Any suggestions?
