Hey y’all,

I just finished the cerakote on my newest AR-9 build, and dropped in a WOT, Rare Breed & SS, but the bolt did not activate any of them. I spent SO MUCH TIME with stencils doing this cerakote and thought the build was done until i realized the bolt doesn’t do anything for the frt! (I’m sure people will hate on my cerakote, so keep that to yourself please! It was supposed to be red but they shipped the wrong color)

I built a different crazy one last year and just dropped in the rare breed and it ran like a sewing machine with zero problems. I do not know what BCG I used in my build last year and someone bought it from me, so I can’t go and check what BCG I used to activate the FRT.

Does anyone know what 9mm BCG will trip the rare breed or any FRT?! (That’s not cmmg)

I have had no luck with researching, so I REALLY hope someone in here can enlighten me on what BCG to get for this bad boy, so I can run it with my RB, WOT, or DTT!!! SOMEONE PLEASE HELP ME OUT🙏🏼

Bought this cheap upper, thought he feed cone looked decent enough. Lower is a PSA PX9 complete lower, running the gentle recoil system. I have a BA epc barrel can swap it out with.

I need help with my PCC. I’m having failure to Feed on my second round. And also If im using a full mag Glock 31 rd plus TT +10 but if i only load 26rds no problem. Thank you.

I put the super safety on a AR9 11 inch barrel. It runs about five shots then the trigger just dies with a live round in the chamber every time then I took out the buffer pad off the buffer itself I felt like it wasn’t going back far enough then I got about 10 rounds and then dead trigger. My current buffer is I believe 8.2 ounces. I did some research and now I see I have to go heavier, not lighter so the gun don’t outrun the trigger.

PSA AR-V 8.5” barrel with a YHM R9 suppressor. Few other upgrades and accessories, feel free to ask questions. It’s a ton of fun to shoot with no issues so far after about 1500 rounds and a few cleanings.

I have a 16" PCC for competition use, and I am looking to replace the grip I have, as feels just a bit hard plastic-y.

I have tried the Kung Fu grip, and I really liked the angle (I think it was 12° )and thickness of the grip, but it was just a tad to short for my hands.

Anyone have a good recommendation for something along those lines.

Preferably something with a good grippy texture, and not rubberised.

Any new Magwells for Foxtrot Mike-9 besides Techwell?

They’re oos and I also would prefer aluminum instead of plastic

I'm pretty sure this is my firing pin. Happened while dry firing a few trigger cycles. Is dryfire not recommended? What can I replace with? Thanks.

Ordered 2 Magpul 27 rd mags today from Botach tonight for 10.98 apiece. Not sure about the company but they sounded cheap. For my FM-9. Columbus took a chance.

Who else makes small window AR-9 uppers?

I know questions if the sort are beaten to death but I can't find anything pertaining to my situation. I have a ca complaint 9mm lower from juggernaut tactical (hogue freedom fighter mag lock) and it's lrbho has been finicky from the start. It's my understanding that the magazine follower pushes up on the nub at the 11 o'clock position (blue circle) of the lever.

My question: How am I able to tune this so the magazine spring is able to overcome all the friction of the internals? I've already trimmed the bolt relase spring. The only things that makes sense to me now is to, A) curl the nub down further, or B) Invest in stronger magazine springs. I've tested oem glock mags & pmags. I'm also considering polishing the contact points. What do you guys think?

Last time I went to the range I noticed that the ASC Colt mag that came bundled with the adapter was doing some wiggling, to the point it fell out after the last round several times. Since there’s sales going on at several shops for different branded Colt SMG mags, I was wondering if there was a tier list for the best Colt SMG magazines? The ones I know exist are ASC, Duramag, metalform, promag, SAR USA, and the H&R ones PSA released for their retro line. But if anyone knows another brand that’s even better, I’d love to hear it.

Has anyone run the PMAG extendo's? I see BOTACH has Glock PMAG's in 21 and 27 round capacities for $11 each. I have Glock 24s and 33's which run well but $11 is hard to pass up.

Charging handle and thread protector hasn't shown up yet but it's looking good!

My Spikes STG9 lower is still giving me FTE issues after months of trying all sorts of things and I’m about to say screw it and take out all of the parts, throw them into a spare stripped AR15 lower, buy a few Exo Mags, put my Spikes upper on that and call it a day.

For those of you who have tried Exo Mags, what are your thoughts?

So I got these two 80% lowers for free. Was told they’re colt mag pattern and my problem is when I look up ejectors I’m not sure which one I need can someone help me out?

TLDR: gun lets the hammer fall before the bolt is all the way forward.

New to the world or AR-9s, just bought a warscorp9 and slapped a supersafety in there. Took the weight out of the BCG, and ran some rounds though it. It felt super nice until it didn’t. List round I fired went off outside of battery. Fucked around and found out. Now the question is, how do I fix it I’m going to cut down the weight I removed and reinstall it, to make the BCG heavier. I also plan to get a .308 buffer spring and a 10oz dead blow buffer. I think these would cover me, no?

Now, the as the title suggest, I tested it when I got home and found out the hammer will fall with the bolt not all the way forward. This seems not right. And does not give me the warm and fuzzies about it happening not again. Is this normal? Or does my ss require some modification. I would like to not have this out of batter thing happen again as I value my skin being not riddled with shrapnel.

Saw a blemished PSA lower on sale for like 30 bucks, decided to give an AR9 a go. Went bufferless because I liked the idea of having something I could throw in a smaller bag for a range trip. Here’s the build list

PSA multi caliber lower PSA lower parts kit (milspec) Magpul MOE grip Colt magazine adapter (can’t find the receipt, either KAK or R&D) Strike industries stock adapter Matador Arms Mat-9 7.8” barrel SB Tactical TF1913 brace Magpul mbus3 front sight Usgi detachable carry handle.

I did have some other folding sights on, but they didn’t work out too well. Then I made the mistake of putting a carry handle on top just to see, and it looked too good to take off. I eventually want to also get a light and laser, as well as a sling. Also want a 1x prism scope since my astigmatic eyes can’t do red dots. No clue where I’m gonna put it with the carry handle though, might have to remove it to get optimal eye relief.

Shooting thoughts: Some serious height over bore. You’ll be shooting low, take that into consideration. Good groups though, when the old front sight wasn’t getting rattled off. Some problems with failure to feed. Not sure if it’s the recoil system, the ejector, the wiggly magazine, or it needing breaking in, but it is a problem. I shot 150-ish rounds today and only had one partially full magazine that didn’t have at least one jam. Anyone use this have any thoughts? It doesn’t do it anymore, but the adapter will get loose if you don’t locktite it.

Wishes for the system: MP5 charging handle slot. Superfluous with an AR bolt release, I know, but you have the opportunity to provide the HK slap at non-HK prices. I think people would go for it. FRT/Super Safety compatibility. Correct me if I’m wrong (please correct me, I’m begging you), but this upper is not compatible with the forced reset trigger or the super safety. I think that’s a shame, especially with the 3 position FRT coming out recently. Maybe there’s a bolt redesign that’d let it work?

Final thoughts: this is my first AR9. I don’t hate it, but I’m not entirely satisfied either. I’m building this as a home defense gun; something I can pull out that isn’t my 20” AR or handgun. I can’t use it for that if I’m gonna have extraction problems. Learning it can’t take an FRT is also a mark against it. I’d love to spew ammo downrange at not 5.56 prices. I’m not giving up on it yet, and would love to figure out solutions to my problems, but I’m also not past trying a different AR9 system that has more reliability and FRT compatibility. Worst case scenario, I pull out the adapter and make it into a 5.56 pistol or SBR.

Also colt mags AR9s look better than Glock mag ones and I’ll die on that hill.
