Reasons for QD functionality Login/Join

Playing off the "good reasons to not use a silencer on a rifle" thread, I am curious what others think about QD functionality. It seems to me that it shines most in the same context that most agreed justified going canless: compact size necessity. I also see a benefit when it comes to weapon maintenance. Switching hosts behind the same silencer is another perk. Considering how I feel about silencer use in general though, I don't see any need for QD functionality, in a tactical scenario. I recently saw an interview in which a former SEAL mentioned his early/mid 2000s leadership having him and his teammates take them on/off for "reasons"; he said he was confused as to why then, and still is now. What do the SIGforum pros have to say, regarding silencer QD functionality? I guess it may ultimately boil down to "why not?"; more pros than cons. Cons I perceive are more complicated and more costly.

The military stuff from KAC and SF retains QD functionality, even with a seeming shift toward constant suppression among the special troops. So, there must be a "tactical" reason; though the aforementioned practical reasons are likely enough anyway.

I guess my view is that I'm going to mount a muzzle device any way so why not one that supports QD? I get that if you have a zillion different suppressor types that's probably not a winning argument. But I use surefire on defensive rifles and I mount QD surefire FH's even if its not in my mind to suppress it on a regular enough basis to have the can on there all the time. Only downside is probably cost. But since you can get qd with an A2 is there really anything that isn't a QD mount? Or maybe I misunderstood the question.

I guess the question is "what are 'dynamic' or tactical reasons for QD functionality?"

Ten years ago, it seemed to me that silencer manufacturers and purchasers cared about the "quickness" of QD actions. If how quick it is is important, than surely the QD functionality "under duress" provides some perceived advantage to someone.

In thinking more about it, a scenario in which someone's weapon is damaged to the point of abandonment/destruction in the field, it would prove handy; the silencer could be salvaged prior to destruction of the weapon.

The bottom line is, with so many people favoring 100% suppressed shooting, what scenarios necessitate a QD functionality? It makes administrative removal easier, of course, but does it have true value outside of administrative ease?

The addition of ablative is enabled by QD mounts. I have used this to good effect. Being able to remove the silencer, drool in it, and re-attach it is advantageous in the dark hours. As ridiculous as it sounds, it enables the elimination of flash and greater sound reduction for your first shots. Many circumstances have those first shots being the most important shots.

My reasons for my usage are that it lets me share the can with multiple hosts.

I also like that I can break it off the front of the gun and let it cool but still shoot. This is of course not impossible with a direct thread but when its hot I appreciate it being a QD especially when there is reasonable discussion of heat sleeves being damaging to the can.

I suppose if I needed to make it ultrashort for tight quarters, i.e., we have people that work on ships and may need something quiet for their general work in public spaces that are more open but also be able to shorten it up while passing through certain areas.

Lastly, I could see it being useful if your job is to be quiet but once you make contact and it matters less, you can suppress with it. Thats a hypothetical with more of a theoretical military side application unless things go terribly sideways for the average person.

You're doing this with rifle suppressors?. Everything I've read and heard says not to do this, that you can only get away with this on pistol calibers. Confused

Not too far into this article, there is an excerpt from the KAC NT4 user manual. The page details a couple controversial things: running the silencer "wet", and emergency removal by "shooting off" the silencer.

I am sure it is good all-around advise to not employ ablative in a center-fire rifle silencer, but it isn't a recipe for certain disaster, and it does work. I have done it with my RC2 and OCM5.

I have used both a bit of light oil (RemOil), and saliva. The saliva is easier, of course, and just as effective. The reason I have tried an oil as well, is to avoid the negative effects of introducing water to everything. Though the effects are presumably very minimal, considering the amount of saliva I use: what equates to perhaps one teaspoon.

The effect doesn't last long, but it does reduce the sound and flash of the first few rounds. Those first few rounds are arguably quite important, in most circumstances.
