If you printed it yourself, you just print a new one. If someone else printed it, you measure it, model it, then print it yourself. |

Does anyone know the distance from the center of bore to the top of the picatinny rail? As in height over bore.
Googling is failing me. I just picked one up used and don't have the manual. |

I'm considering getting one of these. I recently handled one for a few minutes and I don't think the LoP is going to be an issue for me. The only real issue I foresee is the awkwardness of the reload, specifically releasing the bolt via that pinch method.
For all of you that have one and use/train with it, is there a technique to drop the bolt (besides running the charging handle) that doesn't require the pinch? Like is there a way to do it with your thumb alone after you've inserted the mag? |

View Quote When I insert the mag the pad of my thumb is basically on the paddle release and my pinkly closest to the ground. I then invert my hand, with my pinky now closest to the sky, and hit the bolt release with the pad of my thumb in a rearward motion. I can try and take pictures if I'm still explaining this poorly. I've found this to be the fastest and most fluid way (for me) to do it. I don't know that the straightened thumb would work, the release is fairly stiff. I tried it a few times and couldn't quite get it. The second knuckle of your index finger would work fine but was a little slower for me than the method I do. You don't have to do the nipple squeeze or use 2 fingers to release the bolt, if that's part of your question. You just need some leverage which can be provided from the rifle being shouldered or braced on something. |

I just use one finger on the bolt release. After inserting the fresh mag with my support hand, I just bring it (support hand) rearward until the pointer finger can hook and yank the release rearward. The rifle is still shouldered. It is rotated somewhat, but still shouldered.

After practicing reloads ... I have no qualms about the mechanism ... its simple and it works ... with a mag inserted ... very snag free ... really much about this gun is snag free in use ... still my biggest issue is the magwell ... needs a funnel ...

Don't know who this fella is but shows how capable the Hellion really is from 0-800...

LunarTech just released an extended mag release for the VHS2
|

I'd buy that for a dollar!

So I think my Hellion might be headed back to Springfield. I took it to the range yesterday and it started out fine. About the 3rd mag in I get a dead trigger. Ejected the round and noticed a very light primer strike. Ran a few more rounds and then got a dead trigger again - same thing. After that, it started getting down to every other shot being a dead trigger - eject the round and notice a light primer strike. I'd manually cycle the charging handle and get a good shot. But any recoil induced cycle would get me a light primer strike. This is only about my 3rd range trip with it - the other two being trouble free.
I took it home and disassembled it and when I popped the stock off the BCG came with it. I noticed it was pretty hard to separate the stock/recoil spring assemble from the BCG - it took significant force. I thoroughly cleaned everything and reassembled and noticed the same thing - stock/recoil spring assembly is hard to get inserted into the BCG. When manually cycling it, I notice there's a slight hang-up about halfway through the travel. I think I might have a slightly bent guide rod or every-so-slightly out of spec guide rod hole in the BCG. My guess is that this small hang-up is enough to induce a short stroke causing it to not go 100% into battery and also inducing a light primer strike. I did some googling and haven't read of this happening to anyone else. I don't think it's ammo related. I'm shooting PPU M193, so decent stuff. I've also not had one malfunction with this same lot of ammo shooting in my AR. Kinda sucks because I was just getting into a groove with the Hellion and I do think it's a great platform, I may have just gotten a lemon. Hopefully this isn't a headache dealing with Springfield. I've never had to send a gun in for warranty work. |

So I stripped it back down and did a little more work. I didn't notice any gummed up lube points in the firing pin channel or piston, but I went ahead and cleaned them thoroughly anyway. I did notice a "groove" on the guide rod. That grooved spot is exactly where you can feel a hang-up during manual cycling. I hit it with a couple different scotch brite pads to try and smooth it out. Then I oiled everything up and hit the range. No malfunctions through about 50 rounds. We'll see how it goes long term. It does feel better manually cycling it now.
I'm not sure what could have caused this. I'm not even sure if it's normal. Does anyone else's guide rod have any sort of groove or flat spot on it? |
