Default Suppressors: Direct Thread vs. QD

I thought this was a great article written by the folks at Capitol Armory, so I asked their permission to repost it. Ironically, I own the two cans they mention at the bottom of the article. Guess that squarely puts me in the "Texas hunter direct thread" camp.

Original: http://www.capitolarmory.com/blog/di...ppressors.html


On the phone and across the counter at Capitol Armory, we strive to ensure that our customers are well informed about the variety of options before them. Between the paperwork, the wait, and the financial investment, a silencer is a very "big" purchase. Because of that, we try to make you, our customer, feel like you have the knowledge to make an informed decision. One of the most common questions we get from customers evaluating a silencer for their rifle is, "What sort of mount is best?"

Fundamentally, there are only two ways to effectively attach a silencer to the end of your rifle. The first is by means of a direct thread interface. Simply thread the silencer on until it is tight, and you are good to go.

The second method is by way of some sort of muzzle device attachment. Usually, this mount is attached semi permanently to the muzzle of the host rifle and gives a consistent style of mount for the silencer.

We sell silencers that use both types, and have found that each type has positives and negatives that are dependent on the customer's use case.



Direct Thread

Direct thread silencers offer several advantages, namely less weight, more simplicity, and lower cost. All things being equal, a direct thread silencer will be a touch lighter as it doesn't rely on a complex mounting system and it will usually allow for a slightly shorter overall length. Naturally, there are exceptions to every rule, but it is generally understood that direct thread silencers are lighter and shorter.

Direct thread silencers are also much easier for the end user to operate and maintain. There are no latches, pins, or muzzle devices that need to be timed. Simply screw the silencer to the end of the barrel, make sure it is tight, and you now have a suppressed rifle.

Most important to a good portion of our customers - direct thread silencers cost less. Again, there are always exceptions to the rule, but given the simplicity of the mounting system, direct thread silencers are usually less expensive for manufacturers to produce, and those savings get passed along to customers. More importantly, they cost less in the long run as our customers don't have to purchase additional mounts along the way to fit all of their rifles.

From a performance standpoint, we find that well built direct thread silencers usually do as well as brake attach silencers on the sound meter. Similarly, since they orient the same way each time they are screwed to the muzzle, point of impact shift is usually fairly repeatable.



Quick Detach

One of the biggest problems with a direct thread silencer is that it can only be threaded to one thread pitch. The majority of the silencers in our store today are threaded 5/8"-24. That's just fine for the standard .30 caliber rifles on the market, but putting one of those silencers on an AR-15 that is threaded 1/2"-28 will be difficult without an adapter. Using a quick detached or fast attached silencer allows you to use the same silencer on multiple hosts, especially those with oddball metric sizes.

As it relates to strong and durable lockup, quick detach silencers start to really shine against a comparable direct thread model. With the exception of the tapered shoulder that Sig Sauer cuts on their factory rifles, most rifles are threaded with a squared shoulder. With the exception of bull or M24 contoured barrels, this squared shoulder provides very little surface area for frictional lockup. Because of this, direct thread silencers will eventually come loose at some point. Short of gluing or welding the silencer in place, there isn't much a customer can do other than be diligent about checking that their silencer is tight before and during shooting sessions. From this perspective, direct thread silencers do require a bit more management.

A well engineered quick detach system will use a tapered shoulder like the one seen on ThunderBeast's CB Muzzle Device. This tapered shoulder effectively increases the surface area available for frictional lockup, making it much stronger. This ensures that friction alone is enough to keep the silencer in place. Further security can be added by incorporating a locking system like the one seen on Dead Air's KeyMount.

If a customer is planning on using the same silencer on multiple hosts, we usually guide them towards a quick detach model for another reason - muzzle protection. Beyond the durability issues cited above, a quick detach model leaves a device in place that serves to protect the crown of the muzzle from damage for those times when a silencer isn't screwed to the end.



Closing Thoughts

The ideal customer for a direct thread rifle silencer is the guy or gal who has one or two rifles, usually threaded 5/8"-24, but doesn't want to break the bank and doesn't do a lot of high volume shooting that would jar a direct thread silencer loose. For your typical Texas hunter or casual recreational shooter, something like the Sandman Ti or Harvester is usually a perfect fit.

For the customer who has a variety of muzzle thread sizes (especially oddballs) in the safe, does a lot of high volume shooting, and/or wants to move the same silencer between multiple rifles quickly and easily, we usually suggest a silencer that attaches via some sort of muzzle device.

Ultimately, we'd love it if you gave us a call or stopped by the shop, told us what you wanted to accomplish, and let us share our years of experience to help you find the perfect silencer for your needs.

This was always a no brainer for me...if I wanted accuracy, go direct thread. I use direct thread on my AR SBR (mostly for hunting) & bolt guns.

The quick detach are on the defensive AR uppers & SCAR (pending stamp)

I'm a QD guy because the can is a AAC SD 7.62 and having the same can fit many rifles is advantageous.

Does direct thread require a crush washer?

Everything I have read specifically states DO NOT use a crush washer with a direct thread can, as the washer is made to deform slightly under pressure, and this can lead to the bore of the can not being perfectly in line with the bore of the rifle, causing a baffle strike.

Multiple rifles can be DT also. IF you have a bunch of odd ball guns not 5/8x24 then it makes sense for QD.

But if you shoot mostly AR's then seems DT is the way to go. Less weight and cheaper

QD for .30 cal with adapters for multiple platforms include 5.56 which is still very effective.
Direct thread on for 22lr to keep the weight down plus factory threaded barrels are readily available.

This and with heavier recoiling weapons I like the QD because they do not come loose.

And loosening will affect accuracy.

For sure, but if you check it prior to getting in the stand or hunting with thermal you will know ahead of time.

Most people aren't shooting more then a few times at a time

I just get obsessive with load development and want variable nailed down that I can.

I have been using the QD's and like the ability to swap them around. A qd brake or flash hider is a lot easier to get than another suppressor.

Direct Threads you can switch around in a shorter time on any rifle minus the QD mount and flash hider so it's also lighter and shorter

Not if the rifles have different threads.
Say for instance a 6.5 Grendel and .308 and 5.56. With a single 7.62 suppressor you can bounce between all three cals. Again, the qd adapter is much cheaper than 3 suppressors and without the wait.

Buy a $20 1/2-28 to 5/4x24 adapter for the 5.56 and all of a sudden every gun is threaded the same pitch.

Except the 6.5 grendel which is yet another thread.

I like my QDs and you can't change my mind on it.

I ended up buying the QD Sig 762. The price was still reasonable and will be easy to pass between guns. It was also very similar in weight and length to others I considered. Now if only my form 4 would get approved!

Big ole article and failed to mention one of the biggest kickers, repeatably and accuracy after taking can on and off multiple times. Which style is better and how repeatable can you expect 5 shots to be if the can is removed and re attached between each shot?

I have guns that shoot 1 enlarged hole. I use the YHM QD system. I will tell you that as long as I use the SAME suppressor on the rifle the zero stays dead on.

If I use a different suppressor even if it is the same model it will shift slightly (less than 1 MOA).

I have a feeling that a direct thread will be the same.

If your Grendel barrel isnít 5/8x24, you bought it from the wrong place

Enjoy the QD. Theyíre great.

Alexander Arms and all the original Grendel mfg were all 9/16-24.

Only those that jumped in after it took off have 5/8-24.
