Guy in charlotte makes these.Mag block, and the modified 71 round drum.
Works well in full auto as well

Quoted:
Built by Toby Coppley Didn't ask the price, but I recall the drum was $100 NOI they are built by a collaboration of CNC machining (Toby) out of Lexington nc, I believe, and RWX (Ron Williams) from FL. Toby make the full autos and Ron makes the semi. both are sold through the cnc machining website. Toby is a just an overall good guy, easy to work with and a straight shooter. by the way, the guy with the hat should drop that chicken wing

I just got one of the Ron Williams ones. Still need to give it a thorough range test. as is mine, however Toby was helping work out some of the kinks. Ron is a straight up guy as well, but it was more feasible to have Toby help me with it, as we shoot at the same range. I was having some FTF issues, and the barrel extension feed ramp needed a little work. Toby re-worked it some and it shot good until the end of the day, then I was having some extraction issues and stove piping. we figured it was the extractor, and called it good. when I took the BCA apart, I noticed the cam pin was broke  .. removing the bolt head to change the extractor, well, the extractor pin was broke as well  .
just for good measure, I did some MP on the stripped bolt, everything looked good, after that I hit it with some Dye Pen. everything was GTG with no signs of cracking on the locking lugs or around the pin holes. maybe when I get some time I'll throw the broke parts under the scope and take a good look at the fractures. both are changed out now, and I look forward to another range day, range report to follow. |

I had the same problems with mine when i first got it. I needed to dremel the feed ramp down the the middle a little bit. I still break extractor pins. Last weekend i was at the range a 2 of my lugs on my Young NM bolt ripped off while shooting
I break more with this gun then anything else. |

I break more with this gun then anything else. this is what mine needed as well. are you running a standerd extractor spring, or do you have a D-fender in it ? Toby said that the D-fender will cause havoc on the extractor pins. |

Toby said that the D-fender will cause havoc on the extractor pins. Standard. I bought a bunch of extras just in case i break anymore. A heavy buffer also helped a lot with the rounds going into the chamber. They used to get jammed up into the barrel extension a lot. |

the round would nose up ? it's the same issue i was having. are you having to change the whole extractor or just the pin when it breaks ? Yeah. it would hit inside the extension but above the barrel. Once i ground down the ramp and used a heavier buffer it's almost perfect. I still get one every once in a while. Im just replacing the extractor pins. My buffer is either a 5.5 or 6.5 oz |

I break more with this gun then anything else. how's your cam pin ? any signs of wear ? or stress ? the tearing the lugs off, seems like a timing issue ( not unlocking as the BCA moves to the rear ) i'm just trying to troubleshoot both of our issues, as they may be the same problam. were there any signs of wear to the lugs before they broke ? something like peening, burred or excessively worn edges? |

Cam pin was fine. I wasn't really paying attention to any of it before it happened. I put back the bolt that came with Rons upper originally and have been running that in the NM carrier and it seems to be good to go. Performance of the upper got better after i stated using a suppressor. But thats when stuff seems to have started breaking. Not sure if that's a coincidence or not |

The pins broke in the center. I didn't know they were broken till i took the bolt apart to clean it lol ... when the cam pin and extractor pin broke on mine, i had no idea they were broke either, it would still fire, but would have fits of FTE (4-5 times/mag) .. when i was cleaning it is when i notced they were broke. taking a better look at the old extractor the pin holes are worn larger in DIA, then a new one, and the broken pin has about a 25% material loss in the 2 groves cut into it by wear, however it was broken in the middle. The cam pin still makes me wonder, looking at it under the scope i can not see any flaws or defects, and the break looks like a standerd shear type stress fracture. NOI had a few good thoughts about that so i'm going to give his idea a shot and add some weight to the BCA, along with a heavy buffer and a little work on the extractor. time will tell, i hope to get it back to the range this coming week |

I brought mine out Monday. I loaded each of my 3 mags with 5 rounds and they all ran without a hitch....then the mag block broke.  the mag block broke ... WTF ??? which one do you have ? is it the bent SS with the pvc ramp ( RWX) or CNC's all metal one ? |

range report
I switched to a slightly heavier BC, and a simple mod to the extractor .. 2 rounds later FTE, I took the BCG apart, and the extractor pin was broke - in the center then I switched the extractor out to an unmodified one, replaced the extractor pin, and on the 3rd shot, FTE .. take everything apart again, and guess what ... broken extractor pin had to go home, as I am out of pins until my order comes in from delton later this week
