It's nice to see some aftermarket developing for this rifle, but this seems like a step in the wrong direction.

An aftermarket stock/forend should correct the following problems:

The OEM foreend's sling stud and molded-in rail make it hard to get your hand all the way forward.
The rail is a poor accessory attachment point.
No other accessory attachment points.
Even with the barrel fluting the PC carbine is surprisingly a bit front-heavy.
No QD sockets.

Aftermarket foreend should keep the same basic profile as OEM but delete the rail and sling stud (include a flush-mount plug which can be removed to install sling stud). One QD socket on each side towards the rear. One MLOK slot on each side towards the front. If possible, drop a couple ounces vs. OEM.

Fifteen MLOK slots on the handguard pictured above? I get it's mostly for weight savings, but it still screams overkill...

Not a chassis, but Parker Mountain is working on an aluminum MLok fore end.

I agree - too much. Don’t need a full length tactical rail. Just some good mounting points. OEM rail is horrible. I would prefer to keep a slim/tapered profile. Hopefully Magpul has something in the works.

More details about commercially available picatinny rails for the barrel mounted rear sight base...

Taccom now offers a rail for the PC Carbine for $20:

and The Firearm Blog posted an article about Instagram's bkmiller556 rail products (both aluminum and 3D printed) and 3D printed mag well here:

I am still looking for aftermarket vendors to make an improved charging handle and more importantly, an improved stock... (c'mon Magpul!)

Is there wide report of PCC factory rail (receiver) mounted RDS losing zero from repeated take-down?

Not as far as I can tell. As I see it even if the zero shifts a half-inch or so at fifty yards it would still be good enough to do it's job. I'm not going to be head-shooting squirrels with it. On a .22 which may be used for hunting it MAY be a factor. That said I like the factory sights and see no reason to use anything else.

I would have to agree with Bronsonburner, I do not think the zero shift is enough to be worried about in a 9mm carbine that will be used at relatively close range. However, I find a 2 MOA red dot makes for appreciably better accuracy than the Carbine's large ghost ring sight, but the PC9's cheek weld is too low when I mount a red dot on the receiver picatinny rail. Moving the red dot to the barrel rear sight base lowers the sight enough to provide me with a perfect cheek weld.

PMM released their front handguard...Al., M-lock, 150$. A Magpul backpacker type appeals more to me.

Has anyone put the Taccom3g extended magazine release on the PC9. Having some difficulty. Couldn't find a video and the directions don't seem to be working. Could be my lack of skill too.

Edit: Finally figured it out. Works great.

Where did you get it and how much, I need one

Taccom Ruger stuff is just a Google search away.

I emailed tech-sights about making a rear sight and/or a receiver mounted rear with a taller front, they said they would love to make one but haven’t yet.

Looks ok. $150 is more than I would pay. How about a cheaper and lighter polymer version. The front end is heavy enough without adding more weight with a longer heavier aluminum forend.

Is anyone else starting to wonder what is going on with the conversions, both caliber and magazine well? I’d love a .45 conversion and also a beretta 92 magwell adapter.

I would think they would have had most of this developed by release, at least the caliber conversions. I think mag wells are mostly going to be an after market item.

I’m starting to wonder if .40 and .45 are going to happen.

I like the looks of that lone wolf comp!

You make a great point.
One of the follow up tenets of lean production is when you go to fix a situation don't say "What can we change", rather focus on "What should we change".

Going the wrong route leads you to a (laughing) 150$ handguard for the PCC.

Don't they realize a good half the advantage of this carbine is the value proposition? Talk about misreading your market....

Nobody else has created an on-board storage solution for the hex wrenches required to assemble/disassemble the Carbine for field stripping, so I created my own grip plug. More details can be found here:
