I think my barrel dates from 2014-2015 timeframe. |

Is the Ops Inc Muzzle Break that Brownells sells clone correct? Or is only the Allen Engineering the only clone correct currently produced?

Ron has mentioned that brakes and collars coming from "certain other vendors" have been causing problems, they're not concentric and have a myriad of issues.
I'd go through Ron direct or ADCO personally. |

If I understood Ron correctly, it may very well be that the shell of the old OPS Inc is still going somewhere producing brakes and collars, as I believe Ron was wanting originally to buy out/take over OPS but OP's family cut him out of it.
Basically, if stuff isn't actually being advertised as Allen Engineering AEMB and collar, it's not coming from Ron and his guys, or they've chosen to list stuff as OPS because they know people are just searching old posted parts lists for Mk12s looking for Ops Inc parts. But usually you specifically see Allen Engineering listed when it's Ron's parts. This is what I was alluding to above. On the thread in the Suppressor section and the AE owners FB page, there's been a pretty solid number of posts where people have sent in "OPS Inc" brakes and collars to him and he's found a lot of issues, especially with concentricity, and the threading. I don't know if he's straight up identified the source of these various brakes and stuff but it's my understanding that there absolutely are other brakes/collars being made out there not by him, and that they are causing problems. |

I don't think the clone community had quite warmed up to the idea of using the M5 can as opposed to the OG 12th Model yet. We've come a long way since then and I'm not sure I'd use anything but AE parts for a Mk12 build. Not unless it was new-old-stock OPS Inc. parts, that is. Ron's the absolute man and his design is still very relevant I think. |

You live and you learn I suppose. No trade offers so I’m probably just going to list the MK4 for sale and get the Nightforce. |

Has anyone here ever modified a full 1913 swan sleeve for the double/uneven spacing? Pulled the trigger on the one that was posted earlier today in the EE..
Depending how its done/recommendations, I'm debating on just leaving it as it is because of the rarity of the item. I dont want to mess with a unicorn of a gun part in permanent way, the only idea I have would be a "permanent" modification Eta: unless there's a full 1913 railed swan sleeve that's been seen itw?? |

View Quote Lol, you already know who you seek. YO! @Hunterex! As to the full pic, we never saw any ITW pics but there was a prototype 6.8 Late Mod 0 pic with one hand cut for the Gen 3 handguard. Allegedly full pic were requested at some point, and could maybe have gotten a small amount of use somewhere. But, no concrete proof on that. It does make sense though, as with the PVS-22 coming online the desire for mounting clip-on NV became more desirable IMO than running a PEQ-2 on top, which pretty much nobody ever did. Except @Stukas87, but he actually had a PVS-17 mounted when he did that, instead of the Vari-X III that usually was on his SPR. But he was also a guy that ran an ACOG on his as he preferred the lower magnification for how he was using his SPR. |

After reading your reply, sticking to just the full rail seems to be most appealing to me.. the functionality of the full rail makes the most sense, I certainly can understand the reasoning behind the request for them. An ACOG? That would be an interesting thing to see. Would there happen to be a picture of that on one of your glorious picture threads? |

Originally Posted By Dobs013: As far as I know it was just a P/N update. There are no revisions between the two, other than markings. View Quote Yep, they are the same. I have two rails. The 21318 rail I bought from operation parts about 10 months ago. The 99167 marked rail came from Chris at shark arms a few months ago. Both boxes are marked 21318, i think the shark arms stock was new old stock. I'm thinking of moving the 99167 marked rail to the mk12 mod 1 upper and using the 21318 marked rail for a nsw recce build. Both will be painted but its the little details that matter, and i caught myself searching for a new 99167 rail last night.... |

So I think I’m gonna give this barrel nut a go. I ordered a new production barrel nut from PRI, which unless I’m delusional and I may be, is what I need to replicate except with the teeth full aft instead of forward toward the threads. So I should be able to pull all the dimensions needed off the replacement nut. I have a friend with a lathe and a rotary table so I should be able to give it a solid attempt. Thinking of making it out of 17-4 round bar.
