Saw a post on SH saying that a guys UU kit came with a small-hole firing pin and bolt.
Can anyone verify that their kits came with something other than a standard 7.62 bolt? |

I call bullshit. Mark has publicly stated it is not necessary with his design.
Unless of course hell froze over again and he changed his mind? Pete |

Not sure what their deal is, but Lowlight has a problem now with the verticle split scope mounts.
I have seen Larue Mounts cause an issue, it depends on how you install them They are certainly not as "round" as normal rings, In our classes when we noticed the issue, there were Larue Mounts involved There was actually some behind the scenes drama with the USMC using them. The original contract was written as not to use Larue mounts because of the mount part, then they skipped this part of the testing and choose the Larue as there was some discussion about favoritism, but it went forward anyway. When tested they actually do very poorly but things being the way they are, it's not hard to get picked for use regardless of the results. |

There was a pretty lively thread on SH about the split ring issues a while back. It's not just LaRue, but also ADM.
Back on topic, the thread regarding the small pin bolt was started a few months back, it's titled 6.5C Pressure Issues. |

View Quote I haven't observed any issues with my LT mounts, but then again, I only dial to zero and don't run the elevation way up if I can use the reticle to hold. I do use an LT104 and an LT745 on .308s, and I've never used horizontal rings. |

View Quote I'm not a real operator,but i do dial my scopes all the time and check their tracking every 6 months. I have yet to notice any issues with my larue mounts and nightforce scopes. Typically if there was a issue it would find me. Pete |

Maybe start a new thread if you guys want to debate the validity of what Frank is saying.
I've still yet to get a straight answer to the topic of this thread. Can anyone confirm what size firing pin their bolt has? Pictures would be even better. If you don't have a large frame UU kit in either 6.5 or .260, please don't chime in. |

For most users, it's irrelevant. There is an advantage when higher pressures are involved - for example when handloading, with high back-pressure suppressors, or in conditions that cause higher pressures (like in extreme heat).
There are also some 6.5 Creedmoor brass-makers that are offering small rifle primer versions to handle higher pressures. These small firing pins work with those primers better. |

Not necessary, but I got tired of guys like Shrek not knowing what they were looking at. As usual, ya can't fight city hall.

Mine appears to be both a large hole, similar to my .260 and 7.62. For the heck of it, check the revision series on your BGC, both of mine are Rev E. I'm not aware of any markings on the bolt, but maybe with a small hole, there's a revision marking. https://www.AR15.Com/media/mediaFiles/52736/IMG_6735_JPG-458460.jpg View Quote |

Set the spring aside, then drop the ejector device back down into it's pocket. Science bitches. . |

Yes,, testing definitely happened and excellent performance ensued. Based on USMC's SSDS being horizontal split LaRue LT840s and not "verticals", there seems to be some confusion on someone's part. Oh well.. ML ETA - True story ... We put in our submission for the SSDS solicitation, and then got busy and essentially forgot about it. About a year later we get a call ... "Sir, this is the Marines, we need you to come to Washington for a signing ceremony." Me - "A what?" "Signing ceremony, Sir, you won our SSDS mount competition, and there will be an award ceremony." Me, befuddled - "Uh, sure thing, what's an SSDS?" "Sir, it's about our Scout Sniper Day Scope mount you sent in a submission for." Oh, uh, right. What dates are available and I'll get back to you." Then I hung up and went to see what in the hell he was talking about. Yeah, so we really worked the "behind the scenes" on that mount. |

Its always cool when you get the first hand on something, thanks Mark.

Since my 260 tobr has only slight primer cratering im thinking it likely is no big deal one way or another,but I'm headed down to grab the bolt on the uu 6.5 creedmore just to see what it looks like. Maybe i drop it in the tobr and see what the primers look like with 5 back to back shots. Just to see if i can see any difference.i have yet to fire the 6.5 creed so i have no brass to look at.
