actionshooter Posted February 15, 2014 Share Posted February 15, 2014 I know some ranges don't allow full power rifles and people are using pistol caliber carbines for 3 gun and 2 gun matches. Been thinking about buying or building a 9mm but was wonder what people are using. There are a lot of magazine options, whats the best for a competition rifle?

MickB Posted February 15, 2014 Share Posted February 15, 2014 Colt 6951 9mm. Use the Metalform mags at half the price of the Colt mags (which are made by Metalform anyway). Mick Link to comment Share on other sites More sharing options...
mscott Posted February 15, 2014 Share Posted February 15, 2014 I have a couple of Mech Techs and a JRC for such occasions. The JRC is less finicky on ammo selection. JP has one I have been looking at, but don't want to spend that much. Link to comment Share on other sites More sharing options...

fishsticks Posted February 16, 2014 Share Posted February 16, 2014 Lone wolf AR in 9mm uses glock mags, which works well since I also shoot a G17. Now if only WA would approve one of the pending SBR bills I'd be set! Link to comment Share on other sites More sharing options...
jimmcc Posted February 16, 2014 Share Posted February 16, 2014 While I was dedicated to Limited I decided I wanted a .40 carbine. I ordered an Olympic Arms A3 that uses Glock mags and have been happy. Just took a couple 22 round mags and Dawson extensions and done. It may have just a small amount more recoil than a 9MM but really smashes down pistol steel! Link to comment Share on other sites More sharing options...
GreenDragon64 Posted February 16, 2014 Share Posted February 16, 2014 Beretta CX4 in 9mm. Have shot numerous 2 gun matches with it and the PX4 to go with it. Furthest range I've been able to shoot it is about 150 yards, wish I could find a longer range here. You can find the CX4 carbine set up to work with either the 92 or PX4 Storm magazines. There are adaptors one can use to convert from one mag style to the other. Link to comment Share on other sites More sharing options...
ropsitos Posted February 16, 2014 Share Posted February 16, 2014 JP GMR-13 on it's way for me. Ordered around thankgiving, estimate was 16 week-ish, so maybe end of March?

Bowman Posted February 16, 2014 Share Posted February 16, 2014 I use a Rock River 9mm AR with 32 round Colt SMG mags. It works well. Link to comment Share on other sites More sharing options...
ben b. Posted February 17, 2014 Share Posted February 17, 2014 At the local pistol-cal match and an upcoming CQB 3G match, I've been using an M1 Carbine with a red dot on it, which I love. A lot of guys there are using CX4 carbines or 9mm ARs. The .30 Carbine smacks steel harder. Link to comment Share on other sites More sharing options...
JimmyZip Posted February 17, 2014 Share Posted February 17, 2014 Can you get 30 rounders for a .30 carbine? How are you mounting your dot? I had a little .30, and that sucker was very reliable. Seems you could load that on a SDB too. Link to comment Share on other sites More sharing options...
StealthyBlagga Posted February 17, 2014 Share Posted February 17, 2014 (edited) I built a 9mm upper half on my SBR. 10" RRA barrel, CMMG ramped bolt, regular 5.56 upper and charging handle. I use a top-drop-in Hahn mag block, and I run either Metalform 32-rounders or modified UZI mags (including a 40-rounder and Frankenmag 63-rounder). The gun handles pretty much the same as my 5.56 rifles, but with more felt recoil due to the blowback system of operation.

twowheels Posted February 17, 2014 Share Posted February 17, 2014 (edited) colt 6951 with colt and metalform mags, free float tube, geissele SSA-E trigger, sights removed and an old eotech I stuck on it.

MickB Posted February 17, 2014 Share Posted February 17, 2014 Yes, you can get 30rd mags for the M1 carbine. KCI mags made in South Korea. They work very well.... Mick Link to comment Share on other sites More sharing options...

Seems you could load that on a SDB too. I tend to use the 15 rd mags more often, but I do have some Korean 30 rd mags that I use occasionally. I did put in the correct mag catch to use the 30 rounders. There is a rail made by Ultimak that replaces the top hand-guard on the M1 Carb, and that is what I did.

Mike_M Posted February 18, 2014 Share Posted February 18, 2014 I've been wondering about this as well as my local range only allows PCCs for it's "tactical" and "multi-gun" matches. So what I don't get is, do I just buy a complete upper that goes on my 556 lower, or do I have to buy a dedicated gun? And can you "build" an upper? I don't think I've seen any barrels or bolts anywhere before, but maybe I'm looking in the wrong places? Also, if I use my 556 lower, do they use different buffers and stuff? (Not sure how the blow back systems work) -Mike Link to comment Share on other sites More sharing options...

If you just do an upper you'll need to buy an adapter that goes into the lower to accept the pistol caliber magazine. For me this seemed like a hassle, so I went with a dedicated rifle using glock mags. Less hassle and I already have the mags for my G17. Lots of variables including budget, and what you already have.

I don't know if they allow PCC for multigun. Could contact Adam Gardner and ask him. You can build an AR upper. It is not hard. You will need a few tools. I priced out building/buying either a 9mm or a .45 upper, and it was expensive & I decided to build a .300 BLK instead. Link to comment Share on other sites More sharing options...

Ben, TCGC's MG match allows .308 - at least it did recently (I was shooting it, along with two [?] other competitors). But your advice is excellent - it's always best to check with the MD. Olympic Arms, although often maligned on the forums, offers a PCC upper. I've been using one happily, and without complaint, for many years/rounds. It doesn't require changing buffers or installing mag-well blocks. Drop it on a 5.56 lower, add the proper mag (Oly, or moded Sten), and shoot pistol ammo. ac Link to comment Share on other sites More sharing options...

Have you been playing around with bullet weights, comps and buffers at all? Wondering if you could get it smoother by using some really light bullets and a healthy scoop of really slow powder, or is there just too much moving mass to do much about it?

MickB Posted February 18, 2014 Share Posted February 18, 2014 This is where use of a hydraulic buffer helps in the 9mm. Makes a pretty big difference...

T.McDevitt Posted February 18, 2014 Share Posted February 18, 2014 JP GMR-13 on it's way for me. Ordered around thankgiving, estimate was 16 week-ish, so maybe end of March? I wanted my short course platform to match my jp15 as close as reasonably possible and I wanted glock mags just because of their availability. I do hate the waiting part I have the JP GMR-13 in 9mm and it has been great, seems to eat anything up to 1.165 OAL shoots great. I put TARAN TACTICAL TTI GLOCK FIREPOWER LARGE BASE PAD on the big mags they holds 36 rounds. It's has be flawless. In my opinion the glock mags are a huge plus Link to comment Share on other sites More sharing options...

I've been picking up factory 115's and 124's to run through it when I get it to see what it likes best, before I start to gather up component bullets. I don't need super accuracy at the likely use distances, but I don't want to give away anything. I hadn't even thought about adding extensions to the mag...I will check those out. Do you use the stock spring? thanks Link to comment Share on other sites More sharing options...
