So i got my gun put together last night after i got my can on i noticed it was loose. Its like it needs to rotate to the next tooth. It wobbles up and down and side to side. Im afraid to shoot the thing as loose as it is. Is this common?
people talk about rotational play but i think i have a little more than rotational. |
| I'm waiting on my SDN-6 still but that doesn't sound right at all, everything I have read and all the videos I have watched shows a real solid mount that doesn't move or wobble at all. You said it's like it needs to rotate another click or so, can it not do that? |
|
I can chime in on rotational play but its not gun related so let's not talk about it....
On serious note, I'd get that checked out. It sounds like its off and it's seating right in between the tooth and it can't go any farther. It's either your mount or your suppressor thread. Either way id get that checked out before you start going Taliban on the range. AAC is very good at emailing back. Email them! I guarantee you Mr. Cade will email you back! |

If you're close to catching the next tooth, then after a thousand rounds or so it will make it around enough to catch. If you're only half way there you can do some grinding on the mount and get it to catch.
There are some write ups on the modification. I fixed a couple of mounts which reduced the movement I was seeing by about 98%. Once a little carbon builds up on the mount there is 0 movement after performing the mod. |

Quoted: I had a mount that was too loose for my liking so I did the mod. Was it pretty easy to do? It seems like it is. Did you just use light sand paper and go around the mount a little at a time? My form 4 for my SDN6 is sitting on the examiner's desk for approval and I've avoided going by the shop to see the can. I ddi test mount it on one rifle and it was really tight. I'm not sure about the other mount, though.

I had the same experience when I first got mine. I've come to accept that the 'wiggle' is not detrimental to either the can, or accuracy. Still.... I had very minor wiggle on one of mine until yesterday. I put about 8 mags through it, then put the SDN6 on my HK91 for a bit, then went back to the previously wiggly mount. Totally solid now. Apparently all that carbon tightened things up. |
| It's fine. One tooth is 7* of rotational play at its worst. Shoot and enjoy! DON'T start griding away at it like some folks on Snipershide did. If you ever have a baffle strike AAC will more than likely tell you to pound sand if you took a dremel to it. Some of my mounts have almost a full tooth of play and still have little POI shift (that's still consistent). I've never had a can get stuck on the mount either. Go shoot some more and have fun. |

But am i supposed to be able to lift the muzzle and move it up down left and right? As long as you have one tooth or less of play it's operating as designed. If you think that's bad you should see the SEI/Fisher .30 cal can I had for a while. You should shake the rifle and feel it flopping around. KAC NT4 cans aren't the tightest when mounted either. It's really not a big deal. |

I just got an order in of 6 SDN6's and associated mounts ( all 51T- FH, MB, brakeouts) for customers and noticed that ALL the cans and mounts are very tight when the guys tried them on the firearms.
A couple required a some light strap wrench help to get the cans off. This latest batch I have is very tight-fitting. It would alarm me if they had much movement. I have seen a bit to many baffle strikes of late on the web. |

I got the call from my dealer about 15 minutes ago that my form 4 came in and I'm headed out the door to pick my SDN-6 up...finally!

I am expecting my stamp for my SBR, mailed on 5-10, any day. Hopefully by the end of the year for my 762SDN-6, which was mailed in early July. |

I remember you getting irritated trying to find an SDN-6 in stock and an 8" 300 BLK Novekse barrel in the early parts of the summer. I've been quietly racing against you...hahaha. Mailed: April 30 Pending: June 8 Problem Status #1: October 3 Problem Status #2: October 17 Approved: October 31 Received: November 5 It would have been an awesomely short waiting time, but the first problem status was because my trust was missing the Schedule of Compensation and the 2nd one was because the dealer forgot "Living" in the applicant name. *Relevancy to Thread: I have 2 mounts - 5.56 Blackout and a 7.62 Brake. Both of them seem to be in the middle of a tooth. There is slight rotational play, but nothing that concerns me. I would like them a little tighter, but I'll just let the carbon build up and tighten the connection. |

I haven't contacted anyone for the duration, just trying to be patient. |

@jmt1271 - My dealer called me about the first problem status. Apparently some examiners are slow to mail out forms, but whoever is helping Shannon Siviero is quick. My dealer would not have even bothered telling me of the second problem status except that I started getting impatient and called every Wednesday morning for the past month. It was a name error. My dealer fixed it and sent it back. @Kalk - Thanks for the heads up. I have a little rotational play but it is minimal. I don't think I'm going to worry about it at all. Here is an awful picture...  |

Unless you are using this suppressor on a precision rifle with an optic that costs more than both the rifle and suppressor put together. I've seen carbon specks on glass from this "perfectly normal" attachment. I guess that's why they started out with 18 tooth, then 51 tooth, and now 90-some tooth mounts... But what do I know? I only own 10 suppressors. Bill |

Like I said...perfectly normal... Specks of carbon on the glass...

If objective, don't you have that same problem no matter what kind of muzzle device is hung out there? Or is it the increased backpressure of the can that's ejecting the specks? |
