That sucks man, but I hope you get it squared away. I enjoy your build threads.

Well. I got everything working good. Got the carrier to stop binding. Everything was going pretty smoothly. I got the barrel in about 3/4 of the way. Then I saw a dreaded torque of the receiver while under load from the press. So the good news I guess is that I bent back the receiver most the way. The bad news is Im likely going to need a new receiver. Its got a slight S curve to the back half of the receiver. This is my own doing and simply not being smart with how I set up the receiver and the press. Im going to try a bit more to salvage this receiver first as all I need to do is get the rails straight and it should work. It didn't damage the front half of the receiver where all the critical dimensions are for the locking flaps. Well see. Pretty disappointed in myself View Quote Honestly if it isn't horrible and top cover still lines up correctly I'd call it salvageable. |

Didn't brace it on the trunnion? Honestly if it isn't horrible and top cover still lines up correctly I'd call it salvageable. View Quote Shame on me I know. I started it without bracing it and it was going pretty easy. Took it down a few times to check and make sure everything was aligned. Last time it just bowed and I went Im honestly surprised it bent so much and didn't simply break. Im working on her and well see. I can now get the carrier about half way so Im doing something right with these bolts and nuts Worst comes to worst I learn from my mistake and get a new receiver. I asked DSA today if theyd do a custom serial number for MAGA762 on a new one and they told me they don't do custom serial numbers |

You take on ambitious projects and bring them to fruition, and we all get to benefit from watching. Sometimes you choose well, sometimes badly. This is an expensive lesson, but those go with any ambitious project. Kudos to you for carrying on undeterred; some would have bandsawed the brand-new receiver into 3 parts and posted pics.

Just waiting for things to show up. Hoping itll all be here before the weekend so I can get started again

I was sort of thinking its some sort of rigged bipod. But like I said the pic isn't good enough to tell. You could very well be right. I was sort of thinking the spring would be internal to the gas tube. But this is pure speculation on my part. With this thing so chopped up its sort of hard to see how everything works together to be able to determine what could be modified to forgo the spring in the stock. Should I change this to a RPD pistol build https://s-media-cache-ak0.pinimg.com/600x315/82/b5/cb/82b5cb1f40c2e7876b15203176c05adc.jpg View Quote |

Going to be building a RPD project myself.
I have a nice Polish parts set with original barrel and waiting on my DS Arms receiver. |

About fucking time. You'd think DSA would be tossing out parts like a 19 year old virgin tossing 20's at a strip club. View Quote I was like mere minutes from saying fuck it and just ordering a RPD(no fucking shit too). Then I saw the message back from them Something about the gunsmith had to make a modification to the ones they had, they may not be complete who knows. First one shipped quick though |

Chase, It'll be 100% worth it in the end to maintain your patience and build it yourself. Dont' give in now!
Think how much better it'll be to look at it and know your hands built it instead of just giving up and ordering it all in one shot. |

View Quote With them responding to the email I wont be purchasing one unless I fuck this one up too I still have received nothing of a invoice or a tracking number. But Ill give it a few days since Ill be out of town. If I get back in town and still haven't heard or received anything I guess Ill hit DSA back up like WTF? |

RPD receiver has indeed shipped today
Looking like Ill have it by the weekend with some luck |

This one seems much nicer.
Plus note theres left over liquid liquid nitrogen at work |

Got the barrel all the way in
Now I just need to push it back about a tiny smidgen to get it to close on a go gauge |

Yup all is well but a solution in this shop to press the barrel a smidgen out View Quote View All Quotes View All Quotes |

I think I got it.
Go gauge locks completely. No go I get a partial lock. But the wings don't fully engage the receiver |

Motivation picture for you Chase... You can do it. Heed well Tim's tips above, these are two of his full auto builds and mine, which he tuned for me a bit. Hola Tim! http://i1033.photobucket.com/albums/a416/kineticeq/Mobile%20Uploads/IMG_5167_zps3lmgs9zs.jpg View Quote |

If you haven't yet pinned the barrel to the reciever.... STOP.
The barrel needs to be pressed all the way to the stop at the feed ramp and then you trim the bolt flaps to set the headspace. If you don't there is a good chance that it won't feed right and those issues can be a nightmare to tune out of the rpd. The new receivers are made with the locking lugs a big short so that there is enough meat on the flaps to trim down. if you are partially locking on a no-go gauge right now you have problems that need to be fixed!!!! When you fire the rpd a few hundred rounds the headspace opens up a bit and will put you over the line of acceptable. Also be sure you pull the extractor out of the bolt when setting headspace. The extractor will hit the ramp under the barrel and give you a false sense of headspace every time. What you want is a pretty tight flap to receiver fit on a go gauge to start with. Then it opens up to about perfect when you fire it some. |

Unless DSA redesigned the recievers this isn't correct. All the RPDs I did the barrel was pressed until headspaced and then assembled. Many thousands of rounds of full auto through those guns. View Quote I'm about to pin the accessories and drill a port. Hopefully test fire goes nice and smooth |
|
Quoted:
Mostly done. I have all the accessories on and seem to be in place. I have yet to pin them. Once I do I'll drill the gas port. I was working on getting the front sight on right. But I decided to sleep on it instead of make mistakes. It'll be finished tomorrow http://i.imgur.com/UBOwgHp.jpg View Quote |

Everything is pinned up but the front sight.
About to go test fire |
|
|
Yeah. It needs some tuning.
Not sure if it's undergassed or what just yet |
|

Quoted:
What is it doing? What size port did you drill? View Quote Some of the rounds are impacting the edge of the receiver. I've chamfered that a bit. But it's almost like the belt isn't being pulled far enough to the right when cycling Used a 5/32 drill for the gas port |
|
Did you test with a short belt to rule out belt drag?
Is your gas block lined up with the port? |

I've got it to run 3 consecutive rounds. But most hang up during feeding. Extraction is good though. But perhaps it needs more gas. I'm just not sure yet Gas setting is set on 3 which is the highest |
