Suppressor Mounts: Direct Thread vs. Quick Attach

SilencerCo’s ASR… The Griffin Plan A… Don’t overlook the Q Plan B (why no plan C?)… And, naturally, the Cherry Bomb…. If all this muzzle muffler jargon feels like a overseas language, worry not. Right this moment, we’re suppressor mounts. Whether or not you wish to sport a direct thread suppressor mount in your rifle or a fast connect, we’ll go over the professionals and cons so you may resolve what may finest for what you might be utilizing your firearm for.

Suppressor Mounts Are available in Two Flavors

Suppressor Mounts

Direct Thread – the place your can connects on to your gun barrel’s muzzle. Easy sufficient. You simply want to ensure your barrel’s threads match the thread sample  in your can.

Suppressor Mounts

Fast Connect – Additionally known as “QD” (fast disconnect). QD suppressor mounts act as a intermediary between your suppressor’s becoming, and your muzzle. They normally take the type of a muzzle system that appears – and typically features – like a brake, or compensator. QD mounts are solely appropriate with sure suppressor mounting caps. That’s the a part of your suppressor that accepts the mount or threads in query.

Direct Thread vs. QD: Execs and Cons

Every mounting system has benefits and downsides. Right here’s what it is best to contemplate if you’re deciding which mounting technique to go together with.

Direct thread is lighter, cheaper, and easier.

Direct-thread suppressors make use of easy threads that match the threads in your muzzle — for many handguns and rifles, it’s both 5/8×24 or 1/2×28. There’s no muzzle system required to suit the can onto the barrel. Putting in and eradicating the suppressor means merely twisting on or off.

Direct thread suppressors can get caught, or come free.

That is the disadvantage of going with direct threads. When a suppressor heats up, the metallic develop and the suppressor’s prone to come free. If you happen to “gorilla-arm” it into place with excessive torque, the warmth and cooling of the suppressor might trigger it to develop into caught. Attempting to get leverage on a skinny metallic tube isn’t simple, and you could possibly injury your suppressor or muzzle.

Going with direct thread fittings additionally means your suppressor’s solely going to work on firearms with the identical thread sample on the muzzle. Which means in case your can’s threaded for five/8×24 muzzles, you gained’t have the ability to match it onto thinner barrels with 1/2×28 threads — even when the bore of your suppressor can accommodate no matter smaller spherical is chambered within the rifle or pistol in query.

QD suppressors are extra handy, and don’t get caught.

Fast-attach suppressor techniques present simple on-and-off fittings, usually ditching threads totally. Some use easy spring rigidity and others use locking rings to supply a safe match that gained’t get free as your barrel heats up and cools off. Fast-attach fittings additionally present a standardized mount. This ensures one suppressor can work on totally different firearms with numerous thread patterns.

QD setups are heavier and costlier.

Including a particular becoming to your muzzle means including weight. It additionally means spending more cash on what’s already an costly funding. Some QD mounts can wobble simply sufficient to trigger a loss in accuracy, too, however this depends upon the attachment technique.

Sorts of QD Suppressor Mounts

quick-attach suppressor attachments fall into three classes: Locking passive, non-locking passive, and locking lively. Locking QD mounts require some form of handbook enter by the person – like twisting or pulling on a metallic ring that slips over a joint. Non-locking QD mounts depend on easy friction and taper mounts to stay seated.

Locking Passive Suppressor Mount

Suppressor Mounts

A passive locking mount supplies one-handed operation. Which means the person has to work together with only one transferring half on the suppressor to have interaction the QD lock. The lock is often a slip ring beneath spring rigidity that requires only a quarter flip or momentary stress on the spring to have interaction the lock. This passive locking mechanism is how SilencerCo’s ASR mounts operate.

Locking Lively Suppressor Mount

Suppressor Mounts

Locking lively mounts use two forms of locking mechanisms, and will require two-handed operation. These QD setups use a major lock that stops the second lock from participating or disengaging till it, too, is unlocked. Within the case of the Surefire SOCOM 556 suppressor, the first lock is a push lever, and the secondary lock is a tapered friction match. Secondary locks can as an alternative be coarse threads, and different major locks may embody a spring-loaded slip ring. Whether or not lively or passive, most locking QD mounts are reserved for heavy-duty suppressors and navy prospects.

Non-Locking Passive Suppressor Mount

Suppressor Mounts

Most QD suppressors use non-locking passive mounts.These QD mounts use easy threads to align and lock the suppressor to the mount with a tapered friction becoming. These mounts are easy, extremely repeatable, and supply wonderful lock-up that doesn’t come free from cold and hot cycles. Non-locking passive mounting is what this author prefers. I run a Q Cherry Bomb on all my muzzles (my 300 BLK SBR is pictured above). The Cherry Bomb matches each 1/2×28 and 5/8×24 muzzles, permitting me to run my .30-caliber suppressor on all my rifles. It additionally doubles as an important flash hider when i’m not operating my can, and it seems to be good besides. Lastly, the perforated design helps disperse and decelerate gasoline within the blast chamber, prolonging the lifetime of my can’s blast baffle and aiding in sound suppression.

Which QD Mount is Greatest, General?

The reply to this query adjustments virtually ever yr. But it surely’s this author’s opinion {that a} threaded taper becoming just like the Q Cherry Bomb supplies the most effective of each worlds. I’ve by no means had my suppressor come free or get caught, and I haven’t misplaced any accuracy utilizing this mount on my long-range bench rifle. The mount you wind up utilizing largely depends upon the suppressor you purchase. Some well-liked fashions solely use sure QD attachments. So, chances are you’ll simply should compromise and follow what’s out there for the can of your selection. What actually issues is your can’s capability to deal with warmth and supply good sound suppression. Talking of warmth, it is best to most likely put money into a very good suppressor cowl to stop burns.
