I wasin your shoes a while back. I still haven't purchased, but this was my threshold question. In the end, I decided that the non-QD type presented a higher possibility of damage to the threads (screwing the suppressor on and off) and the crown (which is normally shielded by the flash suppressor).

I go with QD whenever possible. It is a PITA to move screw on cans from one gun to another.

Using the same can on different guns is probably the biggest advantage. Even if you have different thread pitches on several guns you can get a FS mount that will will thread on and then QD the can to the FS. As for being truly QD, unless you take some oven mitts with you the can is not QD untill it cools back down.

I have owned a lot of those QD mounts. Someone should rename that to QA Mounts. They attach quick, but when you get them hot they are NOT Quick Detach. Even with semi auto, you can get a can to 400-500 degrees with a couple magazines. Who is going to try to take the silencer off then? I seldom remove my 223 silencers, so if I was starting out, I would by what I consider a SEMI QUICK ATTACH system...The Gemtech Halo and the AAC Omni are in this category. GEMTECH HALO MOUNTING SYSTEM  Gemtech Halo AAC OMNI MOUNTING SYSTEM  AAC Omni Both silencers fit right over your standard A2 ($8 each) and you dont have to buy prepriotory flash hiders that can cost over $100 each. When your flashhider is covered by a silencer anyway, why spend the extra bucks? |

Like I say it is not that I am that interested in The QD feature, I actually am leaning toward the thread on, I was just making sure there weren't any pros of the QD feature that I was missing. Thanks for the info and I will welcome any other comments on the question, that may help me in my decision. TOO MANY CHOICES!!! but hay that's half the fun.

I'm not sure the validity of these tests and maybe someone else can add to this or not but on this guys tests he shows that the 3 lug connector is quieter than the screw on. I'm not sure how that is so but his results said it was with the acc evo 9 and trident. Both of them are awesome cans from what i have read and seen and heard. He has video on this page too that corresponds with his sound meter when firing. Now this is with a 9mm so im not sure if that helps when it comes to 5.56 ect.......

If you are going to put the can on a weapon and just leave it on then there's no reason not to use a thread on. If you want the smallest/lightest can possible then a thread on is probably going to be the best bet for that.
But if you are going to be moving the can between several AR15s then a QD makes a lot more sense. Don't think of it as QD, think of it as "moving the can between platforms with no tools required." It's not the can itself that is the issue, it's whatever you want to install on the barrel when the can isn't attached. Pretty much anything other than a plain thread protector or a Vortex is going to require clamping the barrel in a vise to torque ot down, peel washers for timing, etc. But thread protectors don't do anything about flash and the Vortex is expensive enough that buying several wipes out any costs savings of using a thread on vs. QD. |

In the case of the trident which does show a large difference the author mentions that the Trident is shorter when using the thread on mount and the smaller volume could be the reason for the difference. |

Don't the QD adaptors eliminate the chance of the can coming unscrewed during firing? It's not like you can just reach out and check how tight your 500 degree suppressor is mid-string.

Do you have a lot of problems w/ AR silencers coming unscrewed mid string? I'm wanting an AAC Ranger2 and don't want it coming unscrewed.

Not common but it can happen. I saw a recent posting on another site by rsilvers of AAC saying that they had made change to the threads that make them even less likely to unscrew. When you get your Ranger II be sure to post your opinion. I'm considering getting a pair for a couple of 11.5" SBRs. |

I think as far as price and what I am looking for I will probably go with the thread on for the first one. I am wanting to stay around the 500 mark so I am looking at gem-tech, aac, and yhm. All thread on. Thanks for all of the QD discussion.

Rambling thoughts in no particular order...
Fast-attach cans use a mount that makes it easy to install and remove the suppressor on various host weapons. The host weapons could even have different muzzle threads. For example, AAC makes flash suppressor mounts for their M4-1000 and M4-2000 cans in .5x28 (standard AR), 15mm (HK), 9/16x24 (FNC) 13mm (or whatever it is for the AUG; I always forget that one), etc. You could then use the same can on various weapons regardless of host threads. The fast-attach mounts protect the host threads and crown. The fast-attach mounts typically incorporate some sort of flash suppressor, muzzle brake or compensator. These are often helpful when not using the can on the weapon (for example, a hunting rifle in an area where hunting with cans is prohibited). Thread-mount cans are much more likely to loosen during use DEPENDING on use. I have a Ranger II and have had it unthread while using it on a full-auto 11.5" weapon. The Ranger II's thread spec lessens the chance of the can unthreading, but it can still happen. The same can on the same rifle stays put nicely if I am not shooting full-auto or high volume of fire. You should never just put a can on a weapon and leave it. You should always remove the can after use. Why? Condensation forms when the can is cooling. This can lead to rust. At some point the can should be removed from the weapon and the mount/threads cleaned. Thread-mount cans are fine I think for precision rifles and handguns. My auto-loading weapons that get used hard all wear fast-attach cans. YMMV. That's all I can think of off the top of my head. Mark |
