See, you don't need to rip the top off your gun with a dremel tool.  If you lay it flat on a router table, you can "mill" a controlled depth slot on both sides.
The buggered up stuff in the rear sight cavity is epoxy from a scrapped mod. I made a M16 cocking handle, but didn't like how flimsy it was. The top cocking handle is half of the M16 version I made. ------------- My shoes of peace have steel toes. |

I don't like how big it is either, but it's what I had at that moment. I would rather have just the curved section up there or a large diameter uzi style one. Below are pictures of the first version that was a M16 style rear cocking set-up. The handle would retract after you cock it and not move while firing. I just didn't like how flimsy it was (the 1/8" steel rod wouldn't have lasted very long). Evil-98 - I still haven't had time to make any to sell. I also haven't had time to buy a Halo and get a good video of it ripping over 17bps. I'll sell some eventually, but it's almost been a year since I invented it.

I dont think you really need to put that coil thats attached to the rear cocking handle (2nd & 3rd pic) since the rear bolt is goin to be cycling back and forth and all you really need right there between the cocking handle and body of the marker is to put some kind of buffer to prevent the cocking handle in slamming against the rear of the marker.....you know what I mean. Besides all that....thats an awesome mod idea! ------------- Do not steal....the government hates competition!

Evil-Fingers - The coil is a spring to return the handle after cocking. The cocking handle is not attached to the hammer and it does not cycle when the gun is fired. It's hard to see, but there is a tab brazed to the bolt linkage and another one brazed to the steel rod on the cocking handle. ------------- My shoes of peace have steel toes. |

yeah if you have that top cocking half m-16 ring thing up on it, you should try making a FAMAS style mod, that would be very cool -------------

Yes, that's a M203 shroud along with a M249 stock and foregrip. ------------- My shoes of peace have steel toes. |

It's a de-milled one. It has the legal number of receiver cuts. I think it was @$30 and it includes the barrel, mag well, stock, all internals and the select fire trigger group. It is and will remain a paper weight because I have a problem with going to prison forever. ------------- My shoes of peace have steel toes. |

| Its not like its an easy thing to find a new receiver for assault weapons anyway. Very, umm illegal. |

A Sten is the exception. It's a steel pipe with a couple of holes and some parts welded on. It's just not something I want to take a chance on. I only bought it because it because I could and because I wanted to see the dimensions of the thing for a possible future milsim. ------------- My shoes of peace have steel toes. |

I used a mapp gas torch and brazing rod. You just need to sand and degrease the metal very well and then shim the peice of steel so it is centered on the bolt linkage rod when you flow the metal into the joint. It's very tricky to keep everything lined up and straight while heating the joint cherry red and then trying to touch the brazing rod to the joint. The metal tab was shaped to follow the curve of the bolt linkage rod as well. The other fun part is you need a surface to lay the parts on that won't absorb all the heat. Don't ask me how I know this, but ceramic tile will scale/fracture off peices when heated and bricks or cinder blocks are just as bad (not cool when they pop and fling the metal off at your face).
The good news is that it is much stronger than solder and easy to file the excess brass off. ------------- My shoes of peace have steel toes. |

Hey, Johnny! Is there a reason you couldnt have used the original cocking rod for the gun, and simply just drill a hole for the linkage arm in front of it?
There would need to be a quite large slot along the top of the gun, but you could still sand or grind the cocking rod down to make it thinner! It would seem to be easier to me |

You do not want to rotate the hammer and then have to grind a new flat for the sear catch. I also would not want to file down the stock cocking knob/rod, that would be a huge pain.
What I did is a lot easier and quicker than it sounds. All I needed was : 5 min to rout both halves of the reciever. 5 min to shape a piece of 1/16 spring/hard steel. 30 min to figure out how to hold the steel tab and braze it to the bolt linkage. 20 min of grinding/filing/sanding the brazed on tab. The hardest part was then making the knob that bolts onto the tab. I spent several hours on that because I only had a dremel tool to work with. You could just as easily make the tab more narrow at the top and then braze a thin steel tube on it for the knob. Look at it this way. My way, you only modify the receiver a small amount and do not do anything to the hammer. You simply attach something to the bolt linkage and what you do can easily be ground off if need be. Filling in the slot on the side of the receiver is also reversable since it's just epoxy. The only other thing I needed was half the the stupid plastic cocking knob that came with the rocketcock. I just cut it flush with the hammer and put it in to keep the aluminum insert in the hammer still. ------------- My shoes of peace have steel toes. |
