I got my SP5 lower housings back from being “pinned”. They look great and I’m loving the classic look on the SP5s!

You could say I have a type.

Die Hard is a Christmas movie 🍿

I got a FTR for my MP5 and when ever I shoot it doesn't go right away it might be the ammo I'm running. I'm using Aguila High Velocity 22 Long Rifle Ammo 40 Grain Copper Plated Solid Point but its hard to find so I want to swap to something else.

Several of my favorites!

ROF seems on point, where’s the guys with the app? Bolt gap is 0.010. Shot about 150 rounds 147gr only had one FTEject otherwise it ran flawlessly, brand new out of the box.

My ap5 hates flat nose ammo, but loves round nose. Does anyone have the same issue or it it like that for everyone. I tried these more round nose hollow points thinking it would be round enough. The gun hates this shit. My ap5 has been my bump in the night gun for a while but im not ganna run FMJs in the house. What hollow point do u all use?

Ok, kinda what the title says. I have recently been able to order an SP5 finally. I’m new to the platform but always wanted one and want to stick to a more classic 90’s Navy profile.

I’m looking for A3 stock already. One HK LEO marked mag for the vibe. What else would yall recommend? Night sights, tools, what to carry in the range bag, what other brands of magazines are reliable anything and everything yall can recommend. Also someplace to maybe get the full auto bullet engravings.

For uses, this will be range toy, possibly some two gun comps and depending on how I like it possible HD. I’m not TOO worried about cost because I’m already an HK collector and I know they hate us so sticker value isn’t shocking to me.

Evening all trying to figure out a locking piece issue and wanted some insight. AP5-P with a stock running the stock locking piece shot aprox 200 rounds of 124gr nato. Replaced the stock locking piece with a 90 degree and shot 100 or so more rounds of 124 and 115 suppressed and unsuppressed without issue. When I shoot 147grain it will not cycle the bolt. Swapped to a 100 degree with the same result when shooting 147 grain. Went back to the stock locking piece and it ran without issue shooting 124 and 147 grain ammo. I did notice a little more recoil when shooting the 124 grain nato rounds but nothing crazy.

Based off everything I have read this may cause roller dents over long term use. Just wanted to get your thoughts as I would love to shoot 147 grain subs but not if it will damage the receiver. Is there anything I should watch out for if I continue to run the stock locking piece.

I’m thinking about going with Breacher Customs for my AP5-SD conversion to a true SD. I really like the look of the RCM 8” short suppressor, but I’m trying to decide between the 8” and 12” versions.
For those who have actually shot an AP5-SD with the RCM 8” or, even better, have experience with both, how noticeable is the difference in sound? Is the 8” still comfortable to shoot without hearing protection, or is the 12” noticeably quieter?

Still debating on whether I should frt or not.

There just something about the OG MP5 look, finally got my hands on a Aimpoint PRO. Looks 10/10, Durability 10/10, the lower mount with the thumb screw 5/10. I get the functionality of why they did it but it sticks so far off the gun. Planing ahead I ordered a Midwest Industries QD mount for the Pro/comp m4, just waiting on that to be delivered.

My AP5-N
Currently slapped on with:
Midwest Industries alpha folding stock
Midwest Industries suppressor length hand-guard
HKP Vertical Foregrip
Holosun AEMS
Cat MOB suppressor

Thinking about swapping out the lower. Looking at AS Design or Lee Sporting w/ FRTs in them. Any suggestions?

Recently purchased a PAMT-512 from gunmag & recieved the incorrect stock. They are claiming MKE has suddenly changed the design of this stock.

Looking for recommendations that work with the B&T telescopic stock

Hey all, starting a thread on this because there isn’t much help out there. I have a rd3 ambi frt and the bolt seemed to be hitting the ejector lever. I read a few places that people had to bend it to get in the groove. Well… the metal is not pliable and mine snapped. It was hard to even see which way it had to be bent. I next day aired another MKE lever that’ll be here tomorrow. All HK ones are out of stock everywhere. I need some more help and ideas getting this thing aligned right so I don’t break another lever. I can get better pics when the new one comes. Thank you!

Update: pleased to report that the mke replacement actually had a different profile than the one that came in my ap5p and it needed zero modifications to cycle the bolt 🎉 can’t wait to let her eat some.

So, in typical fashion.. my bolt gap is 0.010 and one of my mags won’t lock. Do you just take this on the chin and fix it yourself or is there any sort of help available from MKE? I purchased from dahlonega armory, a drop shipper. I do have a 90 degree LP coming from HK parts. Will that maybe help? Thanks!

edit: heard back from CA. They want the gun returned but cant tell me what they'll do. They said they do not have any other sized rollers in the shop besides factory MKE. They said if it's not repairable the gun would be replaced. I'd rather just keep it and shoot it / put my own rollers in for the downtime and hassle it would take to return/replace it.

As for the mag, i am able to get it to lock with some finesse now. It's clear that the locking slot on the left is a little out of spec. I went ahead and ordered two overwatch precision mags on sale from midway. (i prefer polymer mags anyways)

So I finally snagged myself a stock from Magpul and oh boy. On paper, it is lighter and way more comfortable than A3, has about same length of pull as A2 but is collapsible. Moreover, it has quite nice cheekweld. There is just one problem, my particular example is wobbly and rattly as all hell (not to mention I find it quite ugly in person). On a positive note, I also got Magpul safety lever, which in my opinion is one of the best upgrades one can get for SEF lower.

Picked it up yesterday and fell in love. I plan to frt, sbr and suppress it. I need to find a light mount so if any recommendations feel free to let me know.

Hello all! I am wondering if anyone has any recs for a solid trilug mount? I've heard the YHM or Rugged mount are solid, but wanted to hear from some of yalls firsthand accounts.

Thank you in advance!
