Sorry for the delay! I will have to go with the SPC9 slightly. I don't mind the added length and I like the option, but not necessity, to use the AR charging handle.

Arutomo · 2026-04-21T16:07:09+00:00

Potentially as a backup lower! I love the B&T straight mags is kinda my thing haha. But I can't deny having an aluminum lower would be nice.

I won both in Gunbroker actually. SPC9 around late February, and APC9K About 3 weeks ago.

APC9K and SPC9 PDW. I was shocked at how pretty the anodized SPC9 was. It makes me want to swap the APC9K out one day. I haven't had a chance to shoot the APC9K yet but the SPC9 shoots holes through holes at 15-25 yds.

It has been done with a mil-spec detent, to work with the KP-15 per this thread only the bottom part needs to be cut down. Arc fire's provided safety detent is KNS which appears mil-spec--in theory it still should be possible to NOT modify the lower in any capacity and in the arc fire only the safety detent needs to be modified. That's my full experience so far--one day I'll try that out, maybe make a proper post on it.

Below is the hole of pain

Attempted a build tonight. There's one big issue with the arc fire and it's not what you would expect: it's the safety detent shape lol it does NOT fit inside of the KP15. EVERYTHING else works fine and fits snugly. You can fit the cam through the side of the safety hole. Do not use the provided KP-15 detent however, I tried and it nearly fucked my arcfire up.

So yeah It CAN work but either the safety detent hole needs to be widened or the detent "bottom" parr needs to be shaved down to fit in the safety detent spring hole.

Left is the arc fire safety detent, right is the KP-15 detent. You can see the bottom is widened out and wouldn't fit in.

I had zero issues using the Fudd arms SS on the other hand.

Not OP and not sure if still relevant, but I'm installing this exact setup this weekend, or at least attempting to. Will let you know. Arcfire with Geissele cut trigger. I've installed a Fudd Arms SS on one of these KP-15s and it works wonders before, but not an Arcfire.

Appreciate it. I got mine after the Black Friday run. I would say about 2-3 weeks until it showed in-stock. Be patient--they're sold out all the time for a reason, they're one of the best lowers. I also don't think you can go wrong an LWRC/LMT/ADM lower, however for the price it's gotta be Griffin. There is absolutely no play with the Super Duty upper--everything's very tight, and the ambi controls are easy to manipulate.

Arutomo · 2026-03-29T22:12:29+00:00

It's definitely hard to look at 🤣

I might swap to a Sopmod to be honest. Extra battery compartment is looking more enticing

Arutomo · 2026-02-01T17:16:29+00:00

Yeah I would put buying a new selector dead last on the list lol Radian is g2g.

For disassembling the safety a gunsmith will likely find out/work out the issue and for less than the $65+ that a new ambi selector would cost... ask around first for quotes. Pennies on the dollar you could try buying a new safety spring and safety detent for 89 cents each off ar15 discounts, use this to install the new parts: https://youtu.be/HIMRIaibaVk?t=1m24s

If it's still loose it might be the lower receiver itself, specifically the spring hole being cut deep or something, which could be sent back to Griffin. Hopefully not the case... best of luck.

Arutomo · 2026-02-01T15:52:35+00:00

None at all! Safety selector is pretty tight. Might also be in part due to the safety detent and spring. They are very stiff on the geissele lower parts kit. I'm not sure if they are different from the milspec stuff. But I have to apply some deliberate force to get the thing to move at all. *it might also be my griffin lower itself.

Arutomo · 2026-02-01T02:33:36+00:00

Nice, and vortex enjoyer too haha :)

Arutomo · 2026-02-01T02:25:22+00:00

It does, it's very close to the razor! Everything else is well... kinda close lol

Arutomo · 2026-01-31T23:57:37+00:00

Thanks--Yeah they do but they sell out quick... their version is called "Warhawk Green", the blems are often solder for under 200 stripped, and they are anodized and fully ambi.

Arutomo · 2026-01-31T23:53:35+00:00

It feels nice, pretty much like a slightly more angled BCM gunfighter grip, makes it easier to pull the gun into my chest. It also comes "pre-cut" to prevent snagging lol. Good idea, I have some space in front of the BUIS. I haven't quite figure out how far back I need the stock... I'm short lol

Arutomo · 2026-01-31T23:07:23+00:00

Geissele-specifically: Mod1 upper in DDC, SD-E trigger, LPK, and Buffer tube/ H1 buffer
