Some people like the ASC but everybody says Cproducts are the best when you can find them in stock.

C Products and ASC seem to be the go tos now. I finished up a 7.62 PWS build a few weeks ago. So far I've run the C Products 20 rounders without issue.
The biggest problem at the moment is finding the 30's in stock. I've bought a couple ASC 30's but have not tested them yet. |

I just finished a build this week and ran 140 rounds through it Friday afternoon. I bought two C products, a 30 banana and a 10 rounder. The 30 rounder I only loaded to 25 everytime. Both functioned flawlessly, no hiccups at all. When I bought the mags my LGS only had the C products mags, they recommended them saying they have tried all of the available mags and the C products worked the best.
My build is PSA 16” upper with a Burris 3x scope on a Frontier lower. It took six sighters at 25 then moved to 50 and 100 yards. After a full range day qualifying then staying late to sight this rifle in, in the SE Texas heat I as beat. So my groups were really going to shit! |

I would also like to know, so thank you for the thread.
And BTW... Maglula now makes a Loader / Unloader for AR mags in 7.62x39 http://www.maglula.com/product/ar15-7-62x39-lula/ |

Soo another AR 7.62x39 Granite State build is in the works, it will be a "budget" build by Son #1, it will be mostly a Deer/Hog Rifle... So the main question is this: Which brand of x39mm AR-15 magazine brand does the hive recommend that they have found to be reliable for you ? Any other thoughts or recommendations are welcome... Sounds like you are planning on reloading, but I’ll mention I’ve had good accuracy from Hornady steel case SST’s:  Attached FileI’m still planning to work up some handloads for my upper, but I wouldn’t hesitate to take the Hornady factory SSTs hunting. |

C Products defense run best for me. I started with ASC mags so all of mine are over 5-10 years old now, but none of them ran as good as the CPDs.
Personally, I think it's that black Teflon coating they use. I know some don't like the 'slippery' feel of them, but I think that's part of the reason why they feed so well. Steel cased ammo just isn't as slick as brass case. Also, the springs in the CPD 30s are as strong as the springs in my AK mags, I don't think my ASCs ever had strong springs. I couldn't get my old ones to run at all til I dropped in AK replacement springs. Hopefully they're better now. I've heard good things about the multimag, and no complaints in 7.62x39. But pricey. If I didn't already have plenty of mags in every caliber I shoot I'd try one. May still. One mag I've been tempted to try is the D&H mag, supposed to be made of HEAVY steel and it has a pretty sharp curve like an AK mag. But I hear more bad than good about them, and the only place I can find them is Atlantic Firearms and they sell them 2 as a bundle. |

Thanks fellas for all your replies, keep them coming...Also, plan to give some .308 cal. pills a whirl with the fresh
x39mm Winchester brass cases as well. Plan to keep the pill weights under 150 grains as that is where the x39mm cartridge wheelhouse is zoned... I do find it Interesting that there is a considerable difference in MAP levels between CIP standards and SAAMI MAP standards for the same cartridge... So, the x39 MAP using the CIP standard its 51,488 PSI and using the SAAMI MAP standard it is 45,010 PSI a difference of 6,480 PSI ! The only reason(s) I can see for the difference(s) in pressure between the two agencies that I can gather is chamber dimensions and freebore length, although this requires a little further Investigation... Thanks again fellas. |

I've got a bunch of cpd 30s and they've all been 100%.
On the other hand... I bought ten asc 30s that jammed like crazy. The issue seemed to be that the finish is kinda gummy, like they didn't fully cure it or something and if you push down on the top round and release you can go "one- one thousand" as you watch the stack creep up. Needless to say at the range every other round was some sort of jamm. I seemed to get one mag to work by putting a few rounds in and repeatedly pushing them to the bottom with a yard stick. I think it wore through the gummy finish or something. I bought some mags from JSE surplus advertised as Bushmaster 5rnd and when I got them the follower said asc on it. They caused nose dive jamms! I was able to see that the feedlips were messed up, they weren't even straight, like they'd been bent by hand or something, so I used pliers to bend them to make the rounds sit at a nose up orientation and now they work. Twice I've bought asc. Twice they were shit. I'll spend my money on cpd from now on. |

Quote HistoryQuoted: Same. My Gen 1 wouldn't fit in the magwell, Primary Arms gave me a refund. I was very disappointed. When the Gen 2s came out, I ordered one, have tested it w/ .223 and 7.62x39mm. Longziz sent me 2 more gratis. I need to try one w/ my brother's .458 SOCOM. Read my mind. I just bought (nit transferred) a 458 suppressor so that’s on my short list. PA website doesn’t expressly say it’ll be compatible with 458. That’s what’s holding me back. When I need more of something from PA I’ll add one to the cart. |

The Ross-Zheng site (manufacturer) says specifically they tested it w/ .458 SOCOM, and the mag holds 12 rounds. For those who panic when you see it's unavailable: http://www.primaryarms.com/rze-unimag-multi-caliber-magazine-rze-mag-001b $28, which is $12 less than what I paid for my 1st one. |

Loads... > Winchester factory 124gr. FMJBT brass cased factory loads for Initial testing... > Pro Digital Chrono for Velocity testing... > A box of condoms fully ribbed for extra safety... So the main question is this: Which brand of x39mm AR-15 magazine brand does the hive recommend that they have found to be reliable for you ? Any other thoughts or recommendations are welcome... Fully aware that the x39mm round was never designed to function well in a AR-15 platform...yet we soldier on America. Thanks. I had nothing but problems with 10 brand new ASC mags, 30-rounders. Rounds nose diving into the mag upon feeding, rounds getting stuck in the mag half way and locking the follower. Had nothing to do with my rifle since rounds were getting stuck in the magazine all by themselves before even inserting the mag into the rifle, all 10 mags had the same problem. I was mainly using steel cased ammunition, and I think the inside of the ASC mags finish has too much friction that when combined with steel cased (tula/wolf) ammo, the rounds would get stuck the more you load the magazine. Maybe with brass they would work better, but I don't know. After, I bought 10 C-Products, specifically the Gen 3's, 30-rounders, I have had nothing but 100% reliability and all my old problems gone. Go with the C-Products Defense (CPD) Gen 3 magazines of any capacity. |

So handguards came in, as did the adjustable lw low problued steel gas block, the YHM Bbl. came in also, and
it is quite nice, measured the bore diameter and it came in came at .3100" according to my Swiss Fowler Digital Caliper...The POF flat 3.5 lbs. single stage trigger module came in and it feels great, light and crisp with plenty of hammer force for hard primers...Will be posting pics soon, and will let you fellas know what it looks like when the upper is complete... Stay tuned. |

She is finished...need to clean up all the dust and lint and all.
Later, we will be developing some custom loads using virgin brass cases in both .308 Cal. and .310 Cal. pills. Son #1 also ordered a nice little folding adjustable bi-pod to help make a little more "tacti-cool"... Next will be mounting and laser boring the German Minx scope and those nice and solid Warne ring bases...
