So if I'm understanding this correctly, the new breed of B&T Rotex cans are HUB-Compatible, and ship with a mount which works with all SureFire SOCOM muzzle devices... and this mount is available separately.
So if the can is HUB threaded, and the SF-Compatible mount fits it .... then I can now buy one of these mounts and have ALL my HUB threaded cans fit to all my SF muzzle devices? Right? Am I missing something? |

Yes, although they are pricey @$355. I brought a B&T suppressor which included one for $950. I use it on my B&T SBR with a B&T Rotex/SF Flash Hider. It locks up pretty tight.

I have sold a couple of the stand along HUB and a 556 version of an SRBS. They are all very nice. I have a demo ROTEX 556 Mini K that I like.
FYI, according to a repeat customer, the B&T SF adapter HUB that comes on 556 cans apparently does not work on 762 SF muzzle devices. The customer contacted B&T and they confirmed if it comes with a 556 suppressor it's purposely made NOT to work on 762 devices as a safety measure. |

Something to keep in mind; I contacted CS and they shipped one out to me pretty quickly:
https://bt-usa.com/support/product-support/ B&T HUB Technical Bulletin Through continual research and development, B&T engineers have noted that some generations of SureFire SOCOM 4-Prong muzzle devices have a steeper taper than either open tine WarComp or 3-Prong Flash hider models. These steeper taper dimensions may cause alignment issues when used with B&T Rotex-SF HUB compatible suppressors. The SureFire 4-Prong flash hider is/was used by select US Military and specialized allied NATO units and has seen a limited release on the US commercial market, primarily as a special run purchased and sold by Geissele Automatics on its URG-I Upper Receiver Groups. If you intend on using your B&T Rotex-SF HUB assembly in conjunction with a SureFire SOCOM-Series open tine flash hider, please contact B&T USA Customer Service for an upgraded reinforcement ring provided at no-charge, courtesy of B&T USA. |

This is fantastic news. I already have an RC2 556 but I really wanted my other .30 cal cans to have the same mounting std. Now I can ditch all my keymo stuff.
Thanks guys! |

I assume the B&T adapter must have a 5.56 aperture built into it? |

Yeah, I guess.

The correct HUB female dimension is full threaded bore depth to .5"+ with at least a 1.32" bore ahead of it to .65"+ from the rear. There are several that don't even have that much. There does seem to be 2 versions of it now, and the one with porting on the exterior has a shorter thread tenon, but the large body ahead of them is still going to be problematic in a lot of cans. So make sure your other cans will be able to accept the adapter before ordering more of these things that are threaded 1.375-24 but really are not HUB compatible because other critical dimensions were disregarded. And since we get asked frequently, no, our Bravo extensions will not allow the B&T adapter to work when it otherwise won't fit, as they do have the above detailed female HUB dimensions.  We see a wider variety of suppressors than most; there's a good reason our Warden & trainer conversion adapters are done like this:  |

Quote HistoryOriginally Posted By CJofFL: No. Many manufacturers, including Surefire, make adapters/suppressors fit same caliber or smaller (but not larger) muzzle devices. So, 5.56 suppressor fits 5.56 md, but 7.62 suppressor fits 5.56 md and 7.62 md. They do so with certain go and no go dimensions on the exterior of the md and interior of the adapter/suppressor. Yeah, I was driving when I saw his question. That’s what I thought he was asking. |

I’d guess most K cans would have this problem. I haven’t tried it on anything else. |

I dont know of any manufacturer other than Surefire who does this. One could try to make that case for the Cherry Bomb XL, but that was actually done to accommodate the larger 8.6 blk thread pattern M18x1.5, not the larger bullet diameter. There are numerous "small" cherry bomb pattern MDs up to .45 caliber, including the original Q cherry bomb. |

ETA: And don't get me wrong, I'm not saying it would be a desirable feature for adapters. Whereas it may be a desirable feature for integral proprietary mount suppressors. I used the term adapter before because of the B&T adapter mentioned above by romad99. |
