I tried and tried years back when production went from Ops Inc to Allen Engineering to get a can that was either specially made or bored out to 6.5mm and didn’t get anywhere. I entertained the idea of an AE30 but it’s like 2 ft long and the proportions look weird on a Mk12. I did see someone selling two 6.8 marked suppressors on snipers hide a couple years back but that was during COVID, I don’t think any AE silencers were being made at the time and the guy wanted like $1500 each. The price combined with the ass pain of buying a silencer from someone out of state made it a no go for me. When otter creak started making their version I did send them an email about a 6.5 or 30cal version they said it wasn’t as simple as boring it to 30cal and that’s as far as I got. I had basically given up on the idea when Trajectory Arms came out of left field and made what I’d always wanted. Something with the footprint of the AEM5/Ops 12th but 30cal and rated got 300WM. |

Ah well I was just talking about the raw collar, haha. As for the can, I thought a .30cal M5 was indeed a thing and would be easier to acquire than hunting down something 6.8-specific. I'd do 7.62mm so you could use it for a variety of calibers, but that's just me. |

Hmm, presume they used different materials for the AEM5 30K if it's heavier, while having the same external dimensions and a bigger hole in the middle? The story I got is that it was beefed up a little to handle the more powerful cartridges. I’m guessing thicker baffles and/or more welds. Gives credence to what I was told by Otter Creek about it not being as easy as making a bigger hole. For 6.5G I presume it is that easy with only about 30% more powder than 5.56 but 300WM is a whole different animal. I doubt I’ll ever use it on a 300WM but it’s going to spend a fair amount of time on a 308 so I’m glad the tweaked it. |

Some guy built one back in the 700-800 page section of this topic (can’t remember specifically, reverse image search of this photo should bring it up). He used the 35 mount instead. I like the combo of the 19 & 21 mount and rings. Were these ever used on the MK12 prototypes? |

For all of you A.R.M.S. veterans out there...What do you do if you get a pair of #22s that don't fit the picatinny rail that tight? I know there are dimensional differences between rails, even though the tolerances on a picatinny rail should be relatively tight, shit happens in manufacturing. While reading the thread I have also noted that several other users have stated a lot of variation between rings.
My 22's are not loose by any means, but the levers do not tighten near as much as I think they should. Has anyone successfully shimmed the cam on the rings to get a repeatable re-mount? |

I’m already invested in 6.5G with a Larue upper and reloading stuff. While I don’t own a 6ARC, and I think Hornady is a champ in marketing a supporting new calibers, the real world differences between 6.5G and 6ARC aren’t enough to make me want/need to invest in a new caliber. Plus, I have a 6.5C AR10 upper and 6.5x47L bolt gun, so the 123gr ELD-Ms I use in the 6.5G can pull double duty there. No 6mms in the family. |

Biggest hurdle I'm gonna run into is finding a raw machined SPR collar, on the prototype it looks like they just took a collar straight from the mill and slapped it on before they anodized it. I'm worried sandblasting one might mess with the alignment so I'm gonna call and see if they can ship me one pre-finishing, otherwise I'll find someone with a mill who can make me one. https://i.imgur.com/p92leCT.jpeg Nah bro, call Ron; he'll make that happen easy-peasy. I tried and tried years back when production went from Ops Inc to Allen Engineering to get a can that was either specially made or bored out to 6.5mm and didn’t get anywhere. I entertained the idea of an AE30 but it’s like 2 ft long and the proportions look weird on a Mk12. I did see someone selling two 6.8 marked suppressors on snipers hide a couple years back but that was during COVID, I don’t think any AE silencers were being made at the time and the guy wanted like $1500 each. The price combined with the ass pain of buying a silencer from someone out of state made it a no go for me. When otter creak started making their version I did send them an email about a 6.5 or 30cal version they said it wasn’t as simple as boring it to 30cal and that’s as far as I got. I had basically given up on the idea when Trajectory Arms came out of left field and made what I’d always wanted. Something with the footprint of the AEM5/Ops 12th but 30cal and rated got 300WM. @Mblades Does the AEM5 30K have the same external dims as the .22 AEM5? Might make my crazy 6.5G Mk 12 Mod 1 idea doable... Other than being an oz or two heavier it’s the exact same. Do it! 6.5G Mk12 is best Mk12. Why not a 6mm ARC Mk12? Because it didn’t exist 10+ years ago when I first made a 6.5 Grendel Mk12. Also I don’t have any 6mm guns but I do have 6.5 Creedmoor so I can share 120-123gr bullets between the two. If I was starting from scratch in 2024 I’d probably go 6ARC as that’s seems to have killed the Grendel, Valkyrie and 6.8spc. |

SAM-R  AMU prototype (sadly not my pic, I'll get there one day though)  I've got a NLS #35 and some rings that I could use, but I'm saving that for another idea I've got. Honestly the only hard parts of doing that 6.8 build are the swan sleeve, suppressor, and TRC/TRR, I've already got the sleeve, a spare TRC and FDE TRR, and a set of #21s so I figure it'll go easily. Still trying to figure some minor parts out, I'm not sure if it was a complete PRI upper or assembled on a Colt receiver. I assume the bolt would be PRI as well. I figure I'll use a winged rear iron to make it a bit cheaper, and since the swan sleeve is already winged due to being Gen III cut it won't make too much of a difference. The #19 is NLS wingless though, since it's got the spaced rail slots, might be tricky but I know some people who might have one to spare. I'll use the FDE TRR for the time being unless I find a grey one before I finish the build. If push comes to shove I can trade some stuff I've got, there's only a few parts I have that are special/rare enough that I won't let go no matter what. Most of my stuff is pretty common.

I also figure you can get any profile you want made with any barrel blank you want if you are willing to pay for it and wait for it. |

Do the levers "snap" into place when you close them? As long as it does that it should hold zero. Try measuring the length of the foot with a micrometer, proper length should be around .743-.746". I've got a #76-OS Trijicon RMR mount and the foot on that is .738", it's kinda loose but it still locks in properly and holds zero. That's great, I'll send an email tomorrow!

Quote HistoryOriginally Posted By thatARMSguy: I've actually never seen a wingless Gen III cut swan sleeve, or at the least all the photos I have of them that I can actually see the logo are winged. Could be some older wingless ones in my photo album, most people take pictures of the other side though so I can't tell. I'm sure that would jump the price up from the $950 that PEQ-2-3s are going for these days.
