Quote HistoryQuoted: I will post pictures and video when I get a chance to take it out. It might be a few weeks or so. I have a newborn at the house so it's hard to get away. In the mean time please check out the video I watched and let me know what you think about the play it has front to back. 2:50 http://www.youtube.com/watch?v=Mm-9tzaaHXI&feature=youtube_gdata_player Edit: also how do you think it would work to extend the finger shelf on the stock another 1/8" to compensate for the SD3G trigger being further forward? They sure don't give them away looking at pricing, but they look awesome and good for a ton of applications. |

The S3G might solve the problem of the SD3G flat bow. Same pull weight, curved bow.

Based on my experience with a home brew slide fire on an AK, pull length and reset distance are not critical for a slide fire. I am using the SD3G, but I am trying to build a bump fire gun without slide fire so minimal distances for pull and reset are much more critical. However, pull weight can still matter, esp. depending on the weight of the gun. |

Bump gun without a slide stock eh? How about this? It's pretty old but it might work with the S3G/SD3G. I think he's using something more standard of a trigger:

They don't need any extra time for the bolt to close at the end of the stroke before the firing pin can reach the primer. 9mm's also use a heavy bolt that pushes the gun forward slightly when it returns to battery. I think you could replicate that video with just an SD3G or AR Gold trigger in a standard 9mm setup. If you wanted a higher cyclic rate you could shorten the stroke or use an extended buffer so their is less overall travel during the cycle, this also prevents the bolt catch from breaking when it gets struck by the bolt.

couple of questions, been lurking....'
I am finishing up a dissipator upper on slidefire stock. Quadrail and bipod Anybody have any suggestions on muzzle device? Break or flash hider? Also, what sights are u guys running, I have been looking at an eotech for this type of build. Thanks! |

I'm running a flash hider because I was worried I wouldn't have enough recoil with a muzzle brake to get the trigger to reset, now that I've ran it a bit I think I'm going to throw a muzzle brake on it the next time I take it out.
I think an eotech is a good choice. Any red dot or a low power magnification scope with a good sized eye box will work. Our issue M249's have ACOGs on them now.

The sight picture on the cheapo PA3X I used to have on my gun was surprisingly effective. I think it would be even more so now that I have my Fostech limited in how far the gun and stock can move away from each other. Next time I have my Bump-SAW out I'll take a picture of my DIY slide distance limiter. It's basically a piece of femo clay I took out of my youngest son's art box and made into a tiny gun part. |

I'll cross post this, from the GD thread:
Heres the video I took today. Stupid ios 8 wont let me upload in HD for some reason. So here's the crappy version. I was having trouble. I couldn't get more than a couple shots to fire when trying to hold on top of the buffer tube and pushing forward on the charging handle. As you can see in the vid, when I grabbed the rail (which was hot ) then the reciever and pulled it forward, it ran perfectly.
Also you'll see me run into the charging handle interference, which I will fix for good tonight. Lots of fun. Best $100.00 I ever spent. Well, if you include all the parts for the new gun, more like 6-700

As stated in the other thread, it's probably unintentional down force with your left hand.
Another idea is that it could be your stock tube being a couple of degrees out of rotation making it more sensitive to pressure. |

I was referring to the extra travel the rifle has in the stock system after the rifle has traveled far enough to the rear to reset the trigger.

Quick question:
If YOU were going to make a different Bump-SAW upper, would you care about it being CL or melonited? I am looking at a complete upper that will suit my idea, but the barrel is chromoly. Hoe much faster is this thing going to shoot out? I've never owned a non-CL or Melonited barrel. |
