Quote HistoryOriginally Posted By chase45: Weldy welds I'm pretty happy with how they turned out Well it is definitely better than v1! Great job! Don't forget you can set up a jig to run your cup against if you want arrow straight welds. Might be handy for the sight base and rail, the highly visible weld. |

Might be handy for the sight base and rail, the highly visible weld. Yeah I'm going to practice some dry runs on the rear sight weld later Lmao it sucks because I had fitting the cocking tube to the receiver so tightly. Then when I welded the trunion in the fit went all to hell  . I didn't think about the heat from welding in the trunion opening up that area I just got done fittingBut yes much better than version one which is all we are after. With any luck it should mostly be done today. Waiting for the rail from hk parts still |

Roughly how much do the parts cost and how do you bend the flat? Is everything readily available?

Depending on how many deals you find probably around 1500. You use a jig and some sort of press. Anything can bend metal, the trick is to get it to bend properly. Some home made rigs work awesome, others ruin flats. A factory jig is around 300 |

Welp its official I've discovered i made an error
Oops. Bolt gap grows with the support in vs out That means I set the cocking tube gap up wrong. I thought something was off with the contour not lining up with the tube and the receiver. However its only off a few thousandth vs how much the picture shows So the options are to cut the tube off and reweld in the proper location Or Grind on the cocking tube support. Grindy grind it is. I'm gunna throw in some negative rollers and grind it until there's not a difference in bolt gap and then replace the negative rollers for standard. That should create a good enough gap while not messing with the camming action |

I would trim the cocking support. Is the same item as the g3 or is it different? The g3 part is cheap if you change your mind.

Heres some more glory pics while we wait for the rest of the parts to show up
Perfect nope Much better, for the most part yep. I think Im gunna go hit the spot welds on the trunion one more time just to make sure I got enough penetration on the welds Other than the top rail and the new front sight. She be done.

Thanks my dudes. As long as the test fire goes well it'll get paint next week and be finished for now.
I set the bolt gap down a little just to play with it and see how it reacts with supers and subs So my old one developed slight dimples in the receiver. This was due to there being no buffer in either the carrier or the brace. To prevent this it had to get the sbr treatment. Itll get a collapsible with the proper buffer to ensure longevity. So I probably won't shoot it a ton until I get the permission slip back from the ATF so I can keep it buffered correctly But I can't really resist so I'm probably going to go throw some subs tonight or tmw |

Looks sweet. Are you going to paint it HK black or something else? Also any idea what suppressor you're going to put on it? It's got the trilug after all.

Quote HistoryOriginally Posted By YaBoyKGTho: Looks sweet. Are you going to paint it HK black or something else? Also any idea what suppressor you're going to put on it? It's got the trilug after all. Semi gloss spray paint  . It actually matches my K pretty good which is my only factory cloneI use a 45 can on a tri lug. It sounds pretty good with some water I've been thinking about getting a dedicated can however. Just not sure what I want. Some of the rifle cans I've tried on others 300 guns had a ton of port pop. The 45 can with water conversely has no port pop and rivals my SD in suppression until the water burns off and it gets slight more loud downrange. Honestly I'm impressed with how well the 45 can does. |

I want two new cans here sometime in the coming months I was debating between a omega9k or a 30 cal rifle can. I actually got to play and shoot the omega 9k on a rattler today. It was good for the size. Its tiny. I'm however thinking I want a larger can for more suppression. |

Welp it runs supers fine at a .015/.016 bolt gap but not my current load of subs
With regular rollers the bolt gap is about at .021/.022 but it runs subs fine then |
