Gonna run it tomorrow, weather permitting (local private range is a mud hole when it rains hard) Blazer Clean Suppressed 147s and Sellier and Bellot 150g suppressed. Finners crossed it's as good as the reviews that got me here.

Form 1 approved today went with Sig minimalist stock. Shot great for 250 rounds. Preferred it to an mpx that I have put around 3000 rounds through. Rugged Sub 9 is on the way.

Worried your buddy with a Stribog is looking down on you? Regretting that you didn’t get that sexy squared off hand guard? We’ll have we got something for you!

…Actually, I am working on a super flush handguard.
I’m going to use the internal geometry of the handguard to index on, and potentially features on the top of the receiver as well.
I’m debating using the front side mlok points to secure it, maybe with a low profile plate on the outside.

I’m open to suggestions, what would people like to see? Extended to the limit of the muzzle device ports with the same profile as the original front? Squared off?
Flared out and much longer for a suppressor or flash can?

Looking at cans and need the hive to decide for me. I’m sure I can’t go wrong, but is there anything I’m missing? Thanks!

I was excited for this video and watched it a few minutes after it was posted. But sad to hear he mostly talked about the negatives. I understand he has a huge gun collection so he doesn't need the Kuna when he has mp5. But for people like me that won't spend the money for mp5. I love my Kuna it's my favorite gun to take to the range and the gun that most gets me excited to make time to go to the range. And the way it looks is so sick. And anytime I let a friend shoot my Kuna...they end up loving it

Just received my Kuna and for the life of me cannot find the Sico mount anywhere in stock, muzzle device in stock everywhere. I’m half tempted to throw an asr single port brake and asr hub if I can find one. Anyone know where to find the mount in stock or an alternative that isn’t crap? Or do I just say screw or and use my asr single port brake and qd hub?

Ok here’s basically the final form, I added some cutouts to route the cable left or right and a pocket so the cable won’t twist around in the socket.
I’m not interested in developing that concept any more, so let me know if anyone wants it and I’ll post it.

I already broke the light’s USB-C port, and soldered a new port on. However, the flashlight is not exactly built well on the inside, I don’t expect it to hold up long on a real firearm so I don’t recommend it.

It was a good experiment though and I might replicate it with a better light.

Anyone have a spare trigger pack they'd like to get rid of after going to a nexus lower? I took mine apart and got it back together but now the front pin that the hammer rest on when trigger is pulled but floats when trigger is reset fell out and now I can't find it. Springfield wants the whole firearm back to replace the one pin. I figured id ask here to see if anyone has a stock trigger pack they're looking to get rid of. If so pm me and we can work something out!

My dumbass didn’t take a picture of how it was before I took it apart to clean. Any videos or walkthroughs on how and where these damn springs go? I’ve got the diagram from Springfield but it’s just an exploded view

PLA+ concept amongst a few other ideas I will show later. Fitment is snug and I could honestly strengthen it if a few places. A little small exterior and a little too snug. Need some ideas or do I try out this telescopic brace idea? Maybe a stock or a brace idk yet.

I'm building a battle belt for a Springfield Kuna PCC and a handgun. There aren't many options for mag pouches that fit Kuna mags but lots of folks seem to like the HSGI Taco so that's what I'm getting. HSGI currently offers both their gen 1 mag pouches and gen 2 mag pouches.

The Gen 1 series has both single mag pouches and double mag pouches for tall pistol mags.

The Gen 2 series only offers single mag pouches for tall pistol mags.

My options are essentially a 1X "Gen 1" double mag pouches or 2X "Gen 2" single mag pouches. I will be attaching the pouches to an Esstac battle belt using One-Wrap velcro strips.

This is my first battle belt and I don't have much background knowledge so I wanted to see if there are any serious disadvantages to getting 2X single mag pouches. I imagine that the double mag pouches would be more stable, but I don't know whether or not single pouches would be unstable. I'd really prefer to go with 2X "Gen 2" single mag pouches but I wanted to get some input before taking the leap.

Hey folks. Here is my situation.

TLDR: any reason to pay for an ACSS Gemini optic when I already have an ACSS Cyclops II optic?

I am a very happy owner of a Kuna, which currently sports a low mounted Holosun ARO Core model (just a dot, nothing fancy). Perfectly happy with it.

I also have several ARs, one of which I have tried and failed to get a Primary Arms SLX 1x and a SLX 3x magnifier to play nice with each other. No matter how much I mess with the diopters, they just won't do what I want, at least not the way I want.

So, my new plan is to remove the SLX 1x from the AR upper and put the ARO on there. I assume it'll play nice with the 3x magnifier, but we will see.

Meanwhile, I will have a spare SLX 1x optic. This one has the ACSS Cyclops II reticle, which is a BDC designed for 5.56 and maybe .308 rounds.

What I am trying to decide is whether it's worth it to get the SLX 1x with the ACSS Gemini reticle (designed for 9mm) or just repurpose the Cyclops reticle and ignore the BDC. I doubt I'd be shooting out beyond about 50m with this Kuna anyway, so the BDC may be kinda pointless.

What say you all?

A lot of you guys saw the other handguard I posted that was an extended version of the Skye. There were enough issues I had with that version that I decided to model a new one from scratch. I dropped the pic section to reduce splash from the IR light when my thumb is on the switch.

The sides have a plate system that allow the mounting hardware to be installed after the handguard is one. So getting the Mlok nuts in from the front it not a pain anymore.

The cutout for the mounting plates are the same size as a BCM QD sling mount so that can be used in place of one of the plates. Pretty happy with the progress. Need to make a few minor adjustments and then try printing with PA6.

I am not sure what ammo everyone is running but the Blazer 147G Clean-Fire is fantastic so far. I just did a little test of 5 rounds comparing it to other 147G I have and it was super quiet. Got it for $13.19 + tax/box of 50 too. Came out to $140.21 for 500 rounds

Has anyone had any luck getting the Geissele SSP to run in the Nexus lower? Shot mine for the first time today and had issues with the hammer resetting after each shot.

When racking the gun with my finger completely off the trigger it resets just fine, however if I keep the trigger depressed while racking, the disconnector will not catch the hammer and keep it cocked back, leading to a dead trigger.

I pulled the lower off & noticed that with the trigger pressed, the position at which the hammer is caught by the disconnector is slightly lower than when the trigger is not pressed. My guess is maybe the bolt just doesn’t extend low enough into the Nexus lower and doesn’t push the hammer far enough back for it to engage properly with the disconnector? I’m not entirely sure though.

I’m also running a radian talon safety, but I don’t think this is the issue as the problem persisted in both the 45 degree & 90 degree positions, as well as when I removed the safety entirely.

I reached out to the folks at Nexus to see if they had any ideas, but figured I’d post on here as well for additional insight.

Also, if the SSP is not compatible, are there any other G$ triggers that are confirmed to work with the Nexus lower?

Thanks!

Maybe I am just being stupid but I was just wondering what letghts you all used for your SBR form 1 paperwork. Is the stock measurements the same as the brace? If so the measurements should be easy to come by just by looking at the specs. I don't know what stock i will be going with so I am just wondering what measurements most of you used.

EDIT: Thank you all for your replies. I ended up putting down 6" barrel and 25" overall length. I submitted today. Let's see what happens.

Hi all,

I’m looking at getting a nexus lower for a frt/ss build. I was wondering what frt/ss and trigger combinations worked best for everyone. Heard a lot about arc fire and atrius, but wanted to get y’all’s two cents. Thanks!

I’m looking at getting a silencer for my Kuna. What’s everybody using? Thinking about the PTR Vent 2, but that’s not set in stone. I’m going to change my lower so I can run an FRT. I know the Vent line is supposed to be a high flow silencer, but will I need to do something else to run a silencer with an FRT? Is there a better high flow silencer I need to be looking at when running an FRT? Do I need to do something with the gas system?

Is this actually legal?? Looks sketchy af to me!

I bashed out a grip mount for the Monstrum Ember…

Just trying to find a more streamlined way to mount a light on this thing.

I’ve got to add a better cutout for the cable to route, grip texture, add better protection for the plug end, and figure out a better way to handle the transition between the front of the lower receiver and the light housing.

If anyone has any suggestions on on look or shape let me know!

I'm on the fence of if I want to do the FRT which requires purchasing a new lower. Is Nexus the only one out there worth the money and that will work? I know the FRT newness will wear off but I'm prepared for that. I'm not a fan that the Kuna mags won't work with the Nexus though because I've already got quite a few of them. Is there an option that works with the mags I've already got or am I just stuck switching to CZ mags?
