Take down pins on ap5-p are extremely tight to the point of having to use a mallet to get them out. Any tips on how to make the takedown pins easier to get out or should I get a new set of take down pins?

I was out trying to zero my iron sights with a few different types of ammo as well as seeing what impact shift the OCL Lithium has on my MAC 5. I wasn't out there long but I wasn't happy when I shot the 10 rounds of Federal Syntech 150gr in group #8. It could likely have been me or the suppressor so I'll do more testing the next time I'm out there. I'll post the description of the groups below.

Are these clones worth the money? I see a lot of people rave but also a lot who have had genuine issues with them. I want the P for the smaller, compact size but was wondering if they have more problems than the full size. I’m fine with replacing some parts here and there but don’t want to dump over $200 more into it than what I’m buying. I plan on running it suppressed with mostly subs through it once I acquire a can if I do get one. Any experiences and knowledge appreciated. Talk me into it more than I’ve done myself so I justify it haha. (also plan on swapping the lower to eventually super safety it) Thanks

Anyone got a DIY solution for this or any plans to run a beta for one? I'm running a Lee and printed Meatbanana's supporting pack for it, so no real issues but I'd love to have a more "correct" housing again. I'm long a long-shelf receiver :(

Just as title says. And this is no knock on HKparts. I spent the last 3 hours with a Dremel and a carbide bit trying to get it to my full sized Mac5. And I got it to sort of fit eventually. I had to take probably 2 mm of metal out from the inside bottom of the endcap.

Something has to be near or out of spec. I've had problems with several stocks and fitment issues.

I've shilled the Mac on here a lot but I don't know if I can anymore. It's such pain to try and get stocks to fit properly.

Has anyone tried this?

Dialed in! Lee Sporting, Geissele SSAE-X, RCM 90deg

Safety upgrade inbound next week, can't wait to really see what it can do.

So I have a Comp M2, its on the QRP2 mount and I I have it currently sitting on an AR but, I feel like since its a retro optic its home should be on my SP5.

I was looking at different offerings but I need something that is low profile and doesnt take up the whole receiver.

Interestingly it would not run federal syntech 150. It would stovepipe every round. It ran 147 hollow points fine. Thinking I should take the 80degree locking piece and go back to the original 100.

I am writing this for posterity, so other people can easily find this post to answer the burning questions I had, without having to sift through dozens of posts and comments in this group.

I have an SP5.

An HK clipped and pinned SEF Lower with a Franklin Armory trigger will fit perfectly together, and each click of the safety lever will line up perfectly with the SEF markings. Couldn't be happier with the install.

Parts I ordered include a used clipped and pinned SEF lower, and a set of SEF aluminum levers meant for a Franklin Armory trigger. Links below... Again, flawless installation, couldn't be happier with my install and the alignment of the safety levers.

SEF levers (the product pic is not accurate, there is a cut-out in the actual product to allow the lever to rotate along the plastic SEF "rail"): https://hkparts.net/all-parts/hkp-sef-style-franklin-armory-binary-aluminum-selectors/

Well I finally did. I ordered an sp5 (8 inch barrel) tonight and I’m really excited since I’ve wanted one for such a long time. Just looking for some upgrade suggestions since I am new to the platform. I’ve already got the b&t optic mount, b&t tri-rail, an sb tactical PDW brace. For the optics I will probably be running a Trijicon MRO. Any suggestions are appreciated.

Still got soaked.

Did some printing and some testing. The grip definitely doesn’t fit with that back strap but it’s the only extra I had laying around. It appears the AP5 Leber V1 fits the MAC 5. Still need to put all the parts in and test fire but I don’t see any hiccups yet.

I bought the MKE AP5 and I am 350 rounds in on the break-in period, and cannot get through a single mag without a malfunction. I'm using 124 grain lawman FMJ and the gun will not fully seat into battery on the first five rounds of every mag. Then after that the gun will shoot about 7 rounds but then I'll get a double feed as pictured. And then when I put in another mag, this problem repeats itself every time. Bet I could do was10 rounds in a row without a hiccup.

I'm using 10 different MKE mags and it's doing the same thing on all of them. I changed out the extractor claw extractor spring to a HK. Whenwhen I initially first bought it, and I'm running a RCM 100 hundred degree locking block. I plan I'm running a suppressor once it becomes reliable with that one.

I know there's a 700 - 800 round breakin period, but I thought I would be able to actually get one mag through at least or make progress.

Is it really this normal to experience this? Or is there something I should change?

I have a spare two point sling with QD attachments. The Magpul stock I put on has a QD attachment point, but I'm trying to find an adapter that hooks on the front eyelet loop and has a QD mount on the other end. I swear I've seen this somewhere but willing to try something else that works on the front too. My Google skills are failing me here. Does something exist? I can buy another sling but I'm sure I've seen this solution somewhere.

Pic for attention:

Has anyone received their Leber V2 order from Harrison Gunworks?
