AR9 - 9MM pistols/sbr

[Little Dutch]

For what it's worth, I have a 16" PSA upper on a Spikes Glock mag lower that works great.

ETA: Both the upper and lower were pre-assembled. I ditched the trigger that was in it for something a little smoother, but otherwise left it alone.

No argument, just thought a few folks might be interested in going to the match. It is a really good time.

By far, more SIGs went down in that match than anything else, and NO Sub2000s went down.

I watched a few videos of the matches today. Looks pretty cool, life is too busy to actually get out to see it live. The mags they use in the match are insane. How many rounds are they holding in those?

Most top guys have backed down to 41s. There are some 47s and 57s as well. Most of those are made by swapping the +2 pad on the 9mm Glock 33s with longer pads from MBX or TTI. There are companies out there making 3D printed couplers and pads, but they don't last long, flex and fail. A 41 in the gun and 23s for reloads is the smart money today. That of course may change as folks figure stuff out. I designed three of the stages for the match, 49, 39 and 17 rounds. There will be several in the high 20 to mid 30 round range.

Colt mag guys are typically running 31s, with some custom made into the 40s that they treat like crystal and only run when needed. One guy on my squad last year had some custom 60s, they did not make it through one stage without some sort of bobble to catastrophic failures.

I like the AR 9mm, I have a CMMG lower that works really well with home built and JSE uppers . I still use a Hahn magazine block in a standard AR lower on occasion.

I was looking at the PTR 9mm, that would an excellent although pricey alternative to the Sig or CZ.

I have a CZ and PTR, both are great as long as you know what you are getting.

It's pretty unique looking. Got more pictures of it?

Good ole' MPX... It's a great PCC.. until it's not. I have 2 MPX's and both have seen hard use, the Gen 1 had about 10k through the barrel before it started to choke on me. It has been back to Sig Sauer twice. They replaced the gas system, bolt, extractor, and springs, and it still not 100% like it was pre 10k rounds. The Gen 2 has hiccup'd once or twice but nothing to serious, but it did go down on me hard at the PCC world championships last year which cost me several placements due to the 30 secs of me F* around trying to clear it. With all that said I'm still competing with my MPX, because it is miles ahead any blowback PCC out there, even a fully raced out JP GMR-15 still kicks harder.

HOWEVER I do have a QC10 that I am fiddling with a CMMG guard upper with and I have a GMR-15 on order. Sig is also looking at releasing a Gen 3? MPX or a "PCC" ready MPX that has suppose fixes done to their system. Once they start shipping I'll get in contact with Sig to see what can be done to my Gen 1.

To note: I had a long discussion with TG at RM3G on why he went to the JP GMR-15. Its not that he wanted to, because he does like how the MPX shoots, its the part availability issue that Sig has which I have ran into this issue myself... its seems you need to have 3 MPX's in rotation just so you'll always have one ready for competition while one is with Sig getting fix, and the other being backup when your main goes down

Lucas Oil PCC, Championship is in the books. It had even less MPXs and Scorpions this year. 1st through 4th were AR15 pattern (including Todd Jarrett in 3rd with a JP). 1 Frankengun, 2 JPs, 1 LimCat. Brian Nelson, in 5th tried the MPX one more time. The next 5 were also AR15 pattern, so 9 of the top 10 ran AR15 pattern 9mm PCCs. Lena was 11th with an MPX (Jerry in 13th also with an AR15 pattern). Less Colt pattern mags and pretty much dominance with Glock mags. Even the handful of guys running the new Ruger used Glock mags.

MBX basepads on ETS mags had a good number of failures. 41 round mags (With Taylor Freelance or TTI pads) got the reliability nod with MBX closely behind with a lot of folks running the 57 rounders. Only saw one 47 round MBX. Still lots of failures related to the Tac-Com parts. We did some T&E on buffers: Standard carbine buffer and spring, .308 buffer and spring, JP SCS and Shooting Innovations buffer system. Of those, the Shooting Innovations had the least movements and smoothest operation. Blitzkreig or Shooting Innovations sure seems to be the top two. Foxtrot Mike bolts, then JP bolts for reliability. Lots of QC10 lowers still in the self-built space.
