I have a POF trigger in mine. The "straight drop-in" they apparently call it.

I think the Aero lower is probably a solid choice. I keep breaking stuff (picture) so the forged lower makes me feel better even though the exact cause of this is probably never going to be known. Wear and tear, a quality issue in that piece, dunno. Another problem I had with this old lower was the ejector. The first one lasted a long time but eventually was rounded off so I replaced it the second I had a failure to eject. But the replacement was really soft and started rounding off right away. The Aero ejector so far shows no wear at all. I also cracked a buffer tube. So I'm kinda of the opinion that the buffer matters the most not just because of how your gun/dot behave, but also for the lifespan of the gun. Been running the Taccom for a long time and considering either a stiffer spring, or a buffer system switch. I just recently shot the Kynshot kit that comes with the extra weight and orange Sprinco 308 carbine spring. The ejection distance was reduced in half, same with the "felt" recoil - pretty impressive to me and since you are starting from scratch ... it might make sense. Performance difference between the two not withstanding, I suspect it would reduce wear and tear over time. I only made it to roughly 15K on that lower before breaking things and I'm not sure that's reasonable. Maybe it is. I dunno. But my interest in not breaking things has gone up here in the last year or so. Hope that's helpful.

I'm kinda with you - I really hated the idea of trying an ETS mag. I was 100% sure they were 100% going to fail, and I am still just waiting for it to happen. But I got some because cheap 40s with no extra BS was too much for me to resist. I consider them disposable, and I check them constantly, clean them faithfully and I have to admit that I haven't had any issues. I also agree that the clear thing is kind of a gimmick, and I remember an old Shot Show video of Magpul saying they've never found a clear polymer they considered good enough. Anyway, I am pretty sure I still don't like them, but they are working. And yeah, I'm not a huge volume shooter. I shoot my PCC in a couple club matches a month and prior to primers vanishing I was practicing at least once a week. So I shoot them a fair amount, but not crazy. However, I only actually use a couple at a time so I'm rotating a little bit, but not like 10 mags in rotation. They each have several K on them without any drama. However, at the price, you could have 5 or 6 preloaded for the match and put a lot less stress on each individual mag. Wish I could help with the real problem you're having but it sounds like you've been thorough.

Not at all, it's just that I don't remember. These are slugs from my stash that I've had for .... some time.

Quick update. Shot that club match I mentioned, 5 stages, all with shotgun, about 75-ish shells and a couple slugs. I used the Fiocchi low recoil slugs and 1145fps Estates - 100% for the day.

Yeah you should just to avoid shooting through bare threads.

No idea what is best but after so many years of running AR-type things with the beaver tail I'm not sure I'd like shooting something without it. Guys at my club just run their preferred grip with the gap which is what I would do too. Mine came with the one you see on it which has the angle I like, and the beaver tail. Normally I just avoid finger groove grips because sometimes they work for me, sometimes they don't, but this one feels great so I'm gonna leave it. You could possibly see if you could order one from Typhoon. I run a K2 on everything else and they make a rubberized one, so if I had to change mine, that's probably where I would gravitate, gap or not.

VR80 (and whatever else). Come out of the same factory from my understanding. I ordered the 9 and 19 from Advanced Tactical. Typhoon I think sells them as well, and they list them as 10 and 20 round, but they want about double for them. Maybe that extra is for the helmet and F12 marking on the side, maybe they sell them at MSRP. I can only assume they put a shorter floor plate in them to get 10 and 20 rounds vs 9 and 19. From what I gather, most people just cut the spring guide/floor plate down for the extra round.

Just got a Typhoon F12 a couple weeks ago and I'm about 250 rounds into it is all. It ran 1250fps Estates right off the bat so I haven't bothered to run anything heavier - about 150 of those. It would just about run 1145fps as it got dirtier, but not 100%. I got a #31 drill bit that miked .113 and it would nearly fit into the factory gas ports so I figured it was a good starting point. That cleared out some burrs and maybe opened the ports ever so slightly. It's running 1145fps shells right now. It needs lots more shooting but after 4 or 5 magazines of 9 rounds back to back without a hiccup, signs are pointing in the right direction at least. Mine is marked "Model 12.1" and has much improved welds on the bolt carrier/action arms than pictures I have seen of earlier ones. Next club match is next weekend, so we'll see how it fares when the gremlins are out.

Makes the win that much sweeter, right? I think there are a number of effective techniques for moving the PCC around in tight spaces to make it less of an issue. I have shot both a short 10.5" PCC and 16" shrouded PCC in my local USPSA and Multigun matches and I really thought that it would be a detriment, but not really. Running a carbine (223 or 9mm) is kinda my interest personally, so I think the techniques are just part of the deal if you're into running a rifle. Maybe they carry over from Multigun, although I haven't personally shot a lot of "tight" Multigun courses I guess, compared to USPSA courses. I think the Open shooters have a couple advantages and the PCC shooters have a couple advantages to where the divisions are interesting and if you have some Open shooters who are cool with the PCC crowd to shoot with it makes for a fun match IMO, especially if you are at a similar skill level. There is an Open shooter at my club who is cool about the whole thing and he can beat me a lot of the time when I run PCC and other times I can get ahead of him but it makes it fun. I have a 5.5" Taccom extension on mine, the gun is fairly light - just a little over 6lbs. I would say my setup falls directly in between something like the ULW and a 16" barrel, but I would tend to lean toward lighter up front is better. Good for transitions but also good for snapping the muzzle up or down when exiting a position or moving around something. For me, I naturally grasp the handguard of a carbine just shy of the muzzle of a 10.5" barrel so virtually everything beyond my hand is an aluminum tube. Not much weight out there to move around.

Buddy of mine ordered 2, one for me and one for himself. We went to the all PCC match our local club put on Sunday with zero testing (unless you count loading the mags the night before), easily loaded 41 in them, ran them through the entire match without a single issue in either of our guns. Worked out alright for me - scored a match win. Not a lot of rounds but good enough that I'm going to keep running them and help me start the journey toward recovery of my clear mag/ETS phobia.

Yep, if memory serves, that is correct. ETA: I looked it up real quick and yes, you are correct. I have been using a technique where I am seating the magazine with my left hand as normal but maintain grip of the magazine and use it to transition the gun to my left shoulder. Right hand goes to the handguard, then left hand moves to grip.

I shot this one last month at an all classifier match in PCC. I shot this one 100%, 6.7HF. This is the only 100% I got that day and the only stage I felt was as smooth as I am capable of shooting. I really think that's all it boiled down to. I shot all As and hit the landing and reload. Transitions felt good. It was later in the day and even though I had been practicing weak hand shooting, this was the only stage that it felt "good". I then promptly butchered the next stage.

I shot this last month in PCC at 84%. It is a tricky one and this was my first all classifier match, but super fun for a classifier I thought. I ultimately shot it correctly but did have a brain fade remembering which middle target I had already shot on string 1 even though I thought I had burned it in. Also, I got real carried away on the rearward movement on string 2 and came clear out of the shooting area, had to correct and finish shooting. I think those two things cost me enough time to keep me out of Master territory. On the second string I shot 3 targets, reload 4th target, then move. It would be interesting to try it different ways for sure but I figured that my rearward reload wouldn't be as solid as standing, and assuming I could make up for it with wicked speed is what made me totally miss my mark and step out of the shooting area. I ultimately made Master that day but this stage was fun enough and interesting enough that it's one I would have liked another shot at.

Ah, makes sense.

What makes it bad?

98.44% PCC - last couple matches I just used a single 33rd mag for the entire stage most of the time. I take 2 mags to the line because I have a bad habit of calling a miss on an edge hit based on my dot and double tapping a target, so if I don't have 6 or 7 rounds left on string 5 I'll swap. I don't think I've had a single match shooting PCC where I didn't do that at least once or twice. Any of you guys have this problem? It's cost me a good run multiple times. There isn't time to wait for the sound or even see the impact ... just something I need to work on. I dunno, my gun weights 6lbs on the dot empty so I don't really notice the weight difference I guess. I do notice it a lot more shooting plastic pistols though and I'm far less confident that I'll have 5 shot strings so I change mags at least a couple times in that case.

Guy I know got one that would come apart slowly while shooting. If memory serves the barrel/forend would rotate slightly and then prevent the bolt from going fully into battery. I at least got to witness the "malfunctions" at a Steel Challenge match, but didn't get to handle it personally. He sent it back to Ruger (I believe he said twice), they said it was fine, the outfit he bought it from offers a satisfaction guarantee and eventually just refunded his money.

Do you by chance know what weight buffer came in it?

At the local place I shoot the USPSA guys seems to straight up dislike the idea of PCC and build stages accordingly. For perspective, last time I shot USPSA pistol they used every single wall the club has. I had to throw together a stage at the last minute that morning when someone backed out and there was essentially nothing left to use. There were lots of tight quarters with a maze of walls that were difficult to move a carbine around in, and short pistol shots to avoid any PCC advantage. Still, I think there were a few other PCC shooters out that day. I thought the stages were pretty fun just because they had a different flavor from MG, but I got the impression that there was an effort to foil the PCC shooters. I broke an extractor on my second stage and ended up shooting my pistol anyway. Our Multigun stages have a lot more going on and are much more wide open, making the PCC a lot more fun. But they also typically have a 200 or 250 yard stage that keeps me from using mine until I can suck less at those ranges with a 9mm carbine. Occasionally though, the MG matches only go to 100 yards, which I think is an effort to let the PCC guys come out and play but I don't see a big PCC attendance there either. ETA: Just checked the scores from Saturday, where the longest shot was 100 yards, not a single PCC shooter. Tons of people, including myself shoot PCC at the Steel Challenge matches there but I think PCC is a lot more fun in an action oriented match.

I dunno if it's meant to solve anything real, more like perceived problems in just one person's opinion. Smaller clubs in my area have tried different approaches at a "production" division but I agree, it would be bothersome to fiddle with at a real match. I think it sounds more complicated than it really is though - a standard carbine/rifle buffer and spring. I pictured it less as something to be enforced and more as a way to protect shooters in that division. Everything can and will be gamed, but I tried to make it difficult by making it defined. It's not as if anyone checks anyone's equipment at the club matches I've participated in anyway. A primary concern to me is clubs without a lot of money and shooters without a lot of money and specifically why I said it is an Outlaw concept, most of which can be ignored for the purposes of this thread. The goal is not to solve an existing problem or void anything, because I think each brand of multigun should carry on as it is if it's working, but just to have something else entirely. I don't see much reason to change or attempt to change USPSA Multigun or 3GN rules. @USCSBarney Hey, just throwing it out there for something to talk about. It is just by coincidence that one of my divisions addresses slide-mounted red dots and that's about the only relevance here. I've been a member of a number of forums over the years and those snarky types are found in every single one. They're all the same, easy to ignore.

Practical 3-Gun.pdf Long time lurker of course - interested in divisions quite a bit myself. To the point that I decided to start writing various Outlaw match rules and divisions of my own. Writing them out really helps to find the flaws and I am sure there are still many but I've attached (not sure what that does so this is a test run) a pdf of the current 3-Gun version. It's meant to be an Outlaw match so some of it doesn't apply to the theme of this thread but the divisions I think do. I've been shooting a P09 with a red dot in open at my local club for a couple seasons now and it works out just fine for me at the club level but I don't think it's really viable for someone who is competitive at major matches. https://drive.google.com/file/d/1ycuNhhoji1vyJtA30C7EKSJz7dtjBQ_J/view?usp=sharing Practical 3-Gun.pdf
