Is there an issue of clearance with the 7.62 cans and the SR25 14.5 CC ? I just got a 14.5CC and the muzzle device looks as close to the rail as my CQBs.

But to your point, let's hope KAC already tested the 7.62 cans with the 14.5" uppers and it won't be an issue (although I have my reservations). |

I had to triple check the current fit of my 762QDC on the 14.5" SR25 Mod 2. It's closer than I remembered. My guess is if the collars on the new models are indeed a bit longer, there will be an issue.

So, I just went back a re-read the info provided by Jack in this thread, and watched the shroud install video. I wonder if some of the problem with clearance comes from the raised tabs on the locking collar that are used in conjunction with the shroud. If you look up photos of the 7.62 suppressor, the locking collar doesn’t have the raised tabs like the 5.56 collar does. Wonder if the 7.62 can still use a shroud.

I'm sure @Jack_L will chime in and confirm one way or the other. |

Here’s a question I don’t think has been asked: will there be clearance issues for the 13.5” URX 3.1 on a 14.5” barrel with the new suppressor?
Ive considered swapping my URX 4 for the 3.1 because it looks so good, but i definitely want to retain compatibility for the new suppressor |

I also think there might be a slight bit of add'l length to the locking collar to accommodate the raised tabs...not much, but just enough to cause the issue with clearance on the 11.5" CQB with URX4. As a reference point, here is a pic of my Delta with the new 7.62 can on it. This has a MAMS on it...which I think provides even further clearance than a flash hider due to the design of how you screw it down with a wrench. If you look closely at the pic, the locking collar doesn't appear to extend much past the ball detents on the muzzle device. SO I'm thinking the clearance issue isn't an issue on the 7.62 cans.

The locking collars of the 5.56 suppressors were lengthened to achieve a minimal gap between the shroud and the handguard.
This was not a needed design change for the 7.62 locking collars. |

Our recall notice stated: "Knight’s Armament Company has discovered a potential issue with recently released suppressors that may cause damage to the suppressor during use." I cannot disclose any more than that, as patent pending design features of these new suppressors are KAC IP, but I can say that the issue is far away from "blowing up". |

If I have a PRT suppressor that won’t clear due to my urx4…. Can I just purchase a new (shorter) locking collar and DIY it at home or do I have to obtain an RMA and send my suppressor in to KAC for this fix? Thanks Jack for all your support and info on this thread. |

No signs of overpressure. I believe there was another failure but not near as catastrophic. Our agency boxed up every PRT and sent them back to KAC for testing where they remain. |

Quote HistoryOriginally Posted By Jack_L: When these are being sent in for the recall check we are polling to see what's going to be used on an 11.5 Mod 2 with URX4 and they will be given some options. The fastest solution is to additionally shim the muzzle device for clearance (only .075 is needed), or replace the locking collar, or update to the URX6 (KS-3 configuration). Replacing the locking collar only requires a small flat-head screwdriver. Personally, I would replace the URX4 with the URX6, as it permits use of the shroud. Is it possible to use the shroud with a shimmed muzzle device on the URX4? |

Quote HistoryOriginally Posted By PresampleDepot: lol. @PresampleDepot What’s the laughable part? I think people are generally interested in how KAC might handle repairs with the new generation of 3d printed suppressors, including what limitations there are on repairs. They have already publicly had a recall affecting this product line, so it’s not too unreasonable to assume it may happen again as end users get more time with the product. Before someone pays the premium for a KAC suppressor they may want to know how such a situation might be handled if a baffle strike happens due to a manufacture defect. Sure I can understand if there is user error with the installation that might change how the issue is handled. It still represents a situation users will want to know how it will be handled. Most people won’t be laughing about their expensive suppressor sitting on a form 4 that won’t be repairable. |

There are so many factors at play that can cause a strike, and plenty outside of KAC's control. I doubt you'll see some blanket "yeah we're going to honor someone blowing up a suppressor or getting a cap strike" with no questions asked. It's most likely going to be a case by case basis.
I am not going to speak on their behalf but just give my personal opinion on it, and Jack is responsive enough that he can address it. |

Baffle and cap strikes are in my opinion the most common failures a user will encounter. How a manufacturer deals with this can make or break the success of the product.
Being a dealer for said product and lol’ing a potential customer inquiring about repair of the most common failure seems helpful. |

Posted: 9/13/2023 6:56:22 PM EDT

It's also the most common end user induced suppressor issue. So yeah I did think it was a funny question to ask with literally no other details regarding under what circumstances KAC would repair a suppressor.
