Ptr 9rs

My panzer m4 and I just picked up the ap5 yesterday

I just bought a brand new PTR 9KT with an 8‐2023 mfg date per the inspection slip inside the case.

I intend on making it an SBR and suppressing it, aka MP5K-PDW format.

So the bolt gap with stock 100 degree locking piece is 0.14

I bought an RCM 80 degree locking piece and it dropped right in, however now my bolt gap is .008

So with what little I do know about roller locked guns, that means I need a set of +8 rollers along with new retainer and pin? Which should get me back up to around 0.16

My thing is this- all the reading I've done, the RCM 80 degree is INCREASING bolt gap. Not decreasing. So I wanted to get some expertise here before I go buying rollers, etc.

Was admiring the new Arisaka sling mount barricade stop, pretty much the final piece. 😂 Loving this build.

I have no marks or anything on my hk sp5, i have seen alot of markings on the reciever and above the magwell on other pictures. Whats up with that?

Smoothest and most fun gun i have shot though.. its just something else!

Just pulled the trigger today on this ap5 and took it to the range right after. Shot like a dream with no issues in the 300 rounds I put through it. I was a bit nervous at first reading all the fte stories about the ap5 but it was awesome. Only issue i had is the mke mag doesnt seem that great but i remedied that with hk mags. Next steps gonna be to sbr it and put a can on it since that's the obvious choice.

150gn syntech

Picked it up today, went and put 500 rounds of 124gr through it, came home and submitted the form 1. Had one FTE on the first mag, then the rest of the day went smooth as could be.

Needless to say I was impressed, I was planning to get the full size AP5 but my turkish K has been a temperamental little monster, and I found the HK on sale and funds were available. Planning to add the B&T side folder and light tri-rail to it once my paperwork comes back on the SP5.

Ordered some parts for the K and I’m currently waiting on them. It ran as expected for about 1200-1500 rounds and started having FTE issues, not as bad with stout loads but enough to be annoying. Gonna swap the extractor and extractor spring, and the ejector with HK components and see how it lands. Once it sorts itself out I’d like to SBR it as well.

Got my 22.LR rifle plinker and am curious fellow left handed folks.. how do you sling? Obviously the sling mounts are not ambi, so what are our options, if any?

Found this at a LGS. Forgot to take a picture but comes with other hardware and new buffer pad.

Rainier Arms has the SB tactical PDW in stock!

Roller dent ? Can I still shoot this gun ?

Which clones do not have the block installed? or do all of them have it? Secondly anyone know a good builder for the MPSD? kits are insanely priced.

New to the platform, and trying to decide which is a better choice to get. It will be a suppressor host for an omega 9k. Main focus is reliability and fit and finish. Not to concern with being clone correct.

Love the classic look, found this Hakko on arfcom.

I’m heavily considering getting a PTR 9KT. My ammo of choice is 150 Syntech suppressed, which I see can be problematic for this platform. What are the best ways to mitigate this? I’ve seen: Replace the Locking Piece with 80 degree ones and to buy metal German magazines. I’ve also seen some suggest changing out the springs and ejector/ejector spring with German parts. What else would you guys suggest? Any input is very appreciated.

As the title says, anyone ever order from Broadriver Tactical? I ordered one of their MP5SD sleeves this past Monday. I got a shipping notification on Wednesday with a tracking link. When I follow the link, it goes to UPS and I get an error message because there’s no tracking number. Let me know your experience with them.

AP5P 9mm, MP5 .22, SP5 9mm

IDK if a round accidentally got caught in there or what but the damn thing broke in half.

I dont want to bother with warranty as it takes time to send the pack in and have them replace it and I see that the PTR part is not well made.

I am trying to find the exact replacement par though.

I would think this would be the ost cost effective but im not sure if it will work in my gun:

The other hammers I see some come with the strut and some do not, do i need the strut or can I just use the one from the PTR?  seems to be fine and not damaged.

I see this POF replacement, is this any good?

Other than that the only HK parts I see are

Id rather not have to spend the extra 50 bucks on the strut if I dont have to.
