Being fairly mechanically inclined, I rushed the prep work for my Stormwerx hinge and miss-drilled the holes. This lead to oversizing and adding nuts to the inside, but the buttstock still wiggles regardless of how much torque is applied.
I've contemplated just welding up the holes and re-drilling, but I figured replacing the rear trunion might just be easier. After Google searching for abit, I stumbled across a rear trunion that has tapped holes on the sides to replace the rivets, but I promptly lost the web page that sold them. Is anyone familiar with a rear trunion that can be bolted in instead of riveted? |

Honestly, I would try to secure the first one before taking that drastic step. Can the hinge be welded on?

Can you go with the next size larger tap and use bigger bolts? Pictures of the back of the trunion would be helpful.

fill holes with JB weld the bolt it on and let sit. It will be rock solid

Hinge is aluminum and rear trunion is steel so no they can't be welded together. View Quote View All Quotes View All Quotes Quoted:

Love the Triangle stock by the way! I'll probably be ordering another hinge too sometime soon as this one is taking a beating with the constant re-torques. |

Find someone who can GTAW (TiG) weld and weld the holes then anneal the welds.
Will be a lot easier to drill and tap being annealed. Did you spot drill before the drill? |

View Quote I drilled a pilot hole, but it wasn't in the right location and the difference was exagerated whe I final drilled it. Funny thing is, I was a first class fitter/welder in another life and never would have scewed something this simple up while on the clock. |

Can you put a backing plate on the inside? There's gotta be a better way.

I managed to get nuts on the back side, but due to (I think) the curvature of the trunion, it won't torque down solid. It will get really snug, but after a few rounds I'll notice that the hinge/stock has rotated and gotten loose. Loctite doesn't help either.
Being pretty new to AK's I've never removed a trunion. Is it more indepth than just removing 2 rivets? Getting the rivets out is no sweat, but I no longer have access to a press or dies to form the heads. |

[#11]
If you fill the holes, re-drill, & re-thread, make sure the bolts that come with the new hinge are long enough. When I got my Stormworx hinge the screws were only too short and only about three threads were engaged. It was obvious that the bolt would have pulled the threads out of the trumion. A trip to Ace Hardware and .80 cents later and the job was done. Just needed screws 3/16" longer so they went all the way threw the trunion.

View Quote You can drill the rivets (very carefully), but it's not always as easy as it sounds. I've disassembled a few, and I wouldn't be eager to perform it on a receiver I needed to re-use. Installing the new rear trunnion rivets is nearly impossible, unless you have the correct rivet squeezer. You really don't want to reinstall it with bolts. It can be done, but you'll never be happy with it. |

My hinge originally came with screws long enough to clear the trunion threads and a nut as well, but added material from welding may very well come into play. |

There is a guy on there that sells 5 degree wedges that 'fix' the slant in the back of M92s. When you buy one of his wedges, it comes with a piece of machined steel that fits the curvature on the inside of the trunnion and it has two holes drilled/tapped through it that are compatible with your hinge. Basically a 1 piece 'nut' that is designed to fit that curvature. Problem solved, no welding or other fab work required. |

There seems to be a bit of interest in his product, so if anyone could reach out to him and point him our way that would be a big help. Like I said earlier. I'm still waiting for the other site to approve my account but as soon as I make contact I'll let him know about the demand. I do have have his PayPal email address if anyone would like it.

It takes into account the ~3* slant cut of the receiver and let's the stock mount in line with the barrel. |

Hey AR15.com guys.
Wmjlar15 gave me the heads-up that y'all need some wedges to straighten out your PAP's. His photos depict the wedge set-up as clearly as I can, but I'd be happy to answer any questions. If anyone is interested in purchasing a kit PM me a request, but I only have white kits in stock currently. And thanks Wmjlar15! |

Glad I stumbled on this thread, still waiting on my hinge and stock from Manticore. Got the eFiled stamp approved towards the end of January, but since I didn't want to have the stock in my possession, had to wait another month till it was in stock again. They said early to mid March, Firday morning I glanced and they were in stock to my surprise. So I ordered it. Quick question the wedge is needed if your installing the hinge on a PAP ? It's not needed for the Draco. Correct ?

Forget the Manticore stocks angle or Storwerkz hinge, the deciding factor is if you have a straight edge Draco you don't need the wedge, if your installing it on a PAP then you need the wedge to compensate for the angle on it. View Quote View All Quotes View All Quotes Quoted:
