Part of it has to do with the originals being multiple layers of foam, not just one solid chunk. There are at least 3 main layers in there if you look at originals.
Me, for now I took a few examples of pictures of issued cases, put them on a grid, and tried to measure out rough dimensions. Then I hacked out the foam with a Kabar. It works for the moment. |

Has anyone tried to shave off a bit of the screw yet? Looking to do up a Holland next and knowing if theres a fix for this beforehand would be neat
Also, this seems to be a common issue with BA barrels, does anyone have this issue with a barrel from other manufacturers? |

Re: accuracy stuff...BA's site says they guarantee MOA with match ammo. Might be worth looking into before scraping a barrel. I'm not knocking BA's quality of barrel, but maybe the harmonics of the BA barrel differ from a Douglas, more/less movement? I dont know a whole lot about that stuff, but maybe the case here? ETA: along with the filing of the gas block, before it gets ruled out. It already is scuffed up from the screw, what difference would it really make to file down some? Also, its covered and most of us rattle can the gun anyway, likely no one will ever notice |

Just to be clear so I’m getting this right.
If one was going to go with the Leupold 2.5-8 for a MK12 Mod 1, the correct reticle is the TMR and not a standard Mildot, right? |

Hmm that's 3 of us with BA barrels with similar issues... I also want to do some more testing. I was able to shoot the group posted above with MK262, but that will get spendy. My typical range fodder is the Wolf Gold, which shoots pretty good in my other rifles. You're right though you can spend a lot on ammo chasing it down. I'm not even sure what other H barrels are available, actually. Quote HistoryOriginally Posted By 78Staff:

Quote HistoryOriginally Posted By tamboi:
I actually would disagree, don't post much anymore but I try to watch the thread as frequently as I can. Most of the scopes supplied by Leupold under contract, early ts-30, ts-30a2 and the later 57055 3-9x36 all were mildot. The 2.5-8x36 models supplied under contract from 2006 onwards were 60150 and 67920 were again mildot, these scopes along with the 112633 were all nsn 1005-01-562-0953. What really muddles the waters is that there was probably 6 or 7 companies that actually won contracts to supply the optics to include Leupold, even though all the optics came via Leupold.

Posted in the Holland thread but yeah, asked around and issued Hollands there was no contact, using PRI blocks. It may be that PRI started sending longer screws for some reason, so spacers or cutting down the screws, or hell getting some different ones makes plenty of sense.
But no, there should be no contact in any AR15 system, unlike M14s that basically require tension. |

Took the Mod Juan, my M40A3 Clone and a friend of mine out to a long range day two weeks ago, a lot of fun was had :D
Managed to get her out to 500m (literally her third time on this rifle, she's more into pistols...) with ease (12" plates), 600 was doable (torso sized target) but hard to spot. All with "M193" by GGG. Still my favorite AR Build :)

I would like to get a MK 12 Mod 0 and would like to know opinions if I should go with PRS or Centurion for the upper? Seems like the Centurion doesn't have the Douglas bbl anymore? I guess neither is fully correct because not a Colt BCG or Upper?
Can I just turn my brain off and get either of these and be close other then the Arms sleeve that isn't made anymore? |

How many shots are you guys calling a group? Pretty sure they only "guarantee" 3 shots. I had a few BA barrels. 2 of them would not group well. 1 did <MOA 10 shot groups with the black box Winchester 69gr match ammo from wally but not anything I found in 77gr.
