Suppressor Mounting Systems Compared

What does a suppressor mount actually cost?

Less than almost anything else in the purchase, which is why it gets decided badly. Across the 1,044 live listings in our suppressor-accessory category the median price is $79.90, the quarter-point is $61.69, and the three-quarter point is exactly $100. The whole category tops out at $712.99.

Split by what the part actually does, the three mounting classes separate cleanly:

  • Direct thread adapters (pitch-to-pitch), 190 listings: median $71.99, from $16.00 to $127.99.
  • HUB adapters, 111 listings: median $80.00, from $35.49 to $265.00.
  • QD muzzle devices and brake mounts, 28 listings: median $101.15, from $31.99 to $260.10.

So the entire premium for a quick-detach interface, measured at the median, is about $29 per unit. That is the number people quote when they say mounts do not matter. It is also the wrong number, for a reason we will get to.

First, a caution about the cheap end of this shelf. Price-sorted, it is not mounts at all:

The Cheap End of the Suppressor Accessory Shelf

Shim sets, alignment rods, booster O-rings and wave springs. Useful, consumable, and not a mounting system. If you budget $10 for "a mount" because that is what the first page of results showed you, you have budgeted for the washer.

Does the mount show up in the price of the suppressor itself?

This is the part the adapter price hides. We track 1,264 live suppressor listings, median $847.00. Grouped by the mounting language in the listing title:

Mount named in the titleListings25th pctMedian75th pct
Direct thread229$457.99$623.99$839.99
HUB198$699.00$869.99$999.00
QD86$859.99$1,129.99$1,390.00

The gap between the direct-thread median and the QD median is roughly $506 — about seven times the median price of a mount. And it runs the whole way down: the cheapest suppressors on our shelf are almost all plain direct thread.

The Cheapest Suppressors We Track

Read that grid with one caveat: the two cheapest rows in this category are not suppressors at all — a fingerprint kit and an NFA trust service, both of which are filed here by the retailer. Everything from $99.99 up is a real can, and 1,242 of the 1,264 listings sit at $250 or more.

How many hosts does quick-detach need before it pays for itself?

Here is the arithmetic that the $29 median premium conceals. A direct thread can needs one adapter per thread pitch. A QD can needs one can-side mount plus one muzzle device on every host.

One brand's own shelf makes it concrete without any cross-brand guesswork. Q's listings include a direct mount, a quick-detach mount for its Cherry Bomb system, and the Cherry Bomb brake itself:

One Maker's Mount Ladder, Direct to QD

Prices updated Oct 21, 2026

Price-sorted, that grid runs taper adapters, then the QD mount, then the direct mount, then the brake. The direct-thread route is a single part. The QD route is two parts before you have mounted anything, and then one more brake for every additional rifle. Three hosts on QD, at our category median of $101.15 per muzzle device, is around $303 of muzzle devices against a single $71.99 direct thread adapter.

For scale on the other side: a plain A2 flash hider that does nothing but cover your threads starts at $5.69 in our muzzle device category. A QD mount is roughly eighteen times that, because it has to index a suppressor repeatably rather than just sit there.

The practical rule the catalog supports is the one experienced owners already give: one host, direct thread; several hosts you genuinely swap between, QD. The suppressor buying guide covers the rest of the first-purchase decision, and best suppressor hosts by caliber covers which rifles are worth threading in the first place.

Is the mount a standard, or a brand lock-in?

Mostly a lock-in, and the shelf depth proves it. Counting adapter listings in our suppressor-accessory category by the proprietary system named in the title:

SystemAdapter listingsCan listings
HUB (1.375x24)139204
Tri-lug / 3-lug545
ASR165
Plan B145
Xeno138
Taper mount1221
KeyMo / KeyMicro88
Cherry Bomb / Quickie89

Every proprietary pattern except HUB is a single-digit or low-double-digit shelf. If you buy into one and the maker discontinues the line, or you simply want a different can later, your muzzle devices are scrap. HUB — a shared rear thread rather than one brand's latch — is the only pattern with real depth on both sides, and it is the one worth paying a small premium for if you expect to own more than one suppressor.

Buying the pattern rather than the brand also sidesteps a shopping problem: 440 of those 1,044 accessory listings carry no brand string at all in the feed, so you cannot reliably filter this category by maker even when you know which maker you want.

Does your thread pitch limit which systems you can use?

Yes, and this is the constraint people discover after the stamp clears. Adapter listings by thread pitch:

1/2x28 — 131 listings, from $8.99. 5/8x24 — 101 listings, from $6.09. After that the shelf thins fast: 13.5x1 LH (33), .578x28 (29), M13x1 (26), 9/16x24 (20), 1/2x36 (19), M18x1 (14), 3/4x24 (11), M14x1 (7), 1-3/8x24 (7).

On the can side the same two pitches dominate: 316 suppressor listings name 1/2x28 and 227 name 5/8x24. If your host wears one of those, every system is open to you. If it wears a metric pitch, an AK pitch or an odd pistol pitch, you are shopping a shelf of seven to thirty parts and some systems simply will not have one.

One brand shows what buying by pitch looks like in practice:

One System, Priced Per Thread Pitch

Same part, same price, six different pitches. That flat pricing is the honest version of this market: the mount is not a feature you upgrade, it is a dimension you match. Confirm the pitch with your barrel maker rather than inferring it from caliber — a thread pitch is not a caliber, and muzzle energy vs muzzle velocity is a reminder of how often published numbers get read as the wrong quantity.

Can you wait for a mount to go on sale?

Not usefully, and we can measure that. Across our live catalog:

  • Suppressor accessories: 28.3% stocked by more than one retailer; 32.2% sitting above their own recorded low, median gap 7.49%.
  • Mounts and adapters specifically: 24.8% multi-retailer; 33.2% above their own low.
  • Suppressors themselves: only 10.9% multi-retailer; 28.2% above their own low.
  • Ammunition, for contrast: 29.9% multi-retailer; 69.7% above its own recorded low, median gap 10.61%.

Two-thirds of suppressor hardware is already at or near the cheapest price we have ever recorded for it, and most cans exist at a single retailer, so there is neither a spread to shop nor a discount to wait for. Ammunition is the inverse: most of it is marked up against its own history, which is why the alert belongs on the cartridge, not the mount. Why ammo prices move explains the forces behind that asymmetry, and what a suppressor really costs all in puts the hardware next to the stamp.

Prices in our catalog are item-only — retailer shipping is not published in the feeds we ingest, and on a $50 adapter shipping is a meaningful share of the total. Suppressors also carry dealer-transfer handling that no feed reports. Check both before comparing two listings that look $5 apart.

What the mount really decides

Not sound, not weight, not how the gun shoots. The mount decides which hosts the can serves, and the hosts decide what you spend for the rest of the can's life.

Those two blocks are the whole reason the mount question is worth an hour of thought. A can locked by a single direct thread adapter to one .308 rifle is fed at the upper figure forever. A HUB or QD can that also lands on a threaded rimfire gets fed at the lower one for most of its range sessions — and the floor on .22 LR is about a tenth of the .308 floor as those widgets render today. One $80 adapter changes which of those two lines your practice sits on, which no $500 difference in can price can undo.

If the plan involves a rimfire host, the best .22 LR ammo by bulk, match and hunting use is where to start on the recurring side, and the best ammo for suppressed rifles covers the subsonic question that actually governs how quiet the thing is. Browse the hardware itself under accessories, or compare cartridge costs directly at .22 LR deals.

Four Parts That Illustrate the Choice

Griffin Armament Cam-Lok Barrel Adapter 1/2x28
The one-pitch direct adapter

Griffin Armament Cam-Lok Barrel Adapter 1/2x28

Griffin's Cam-Lok barrel adapter exists in six separate thread pitches at the same shelf price, which is the clearest illustration of how these systems are sold: you buy the pitch, not the part.

Pros

  • ✓Same price across every pitch Griffin offers
  • ✓Stocked by more than one of our retailers

Cons

  • ✗Only useful on a Griffin-pattern can
$50.29Check PriceDetails
Gemtech Direct Thread Adapter for HUB to 1/2x28
The HUB hedge

Gemtech Direct Thread Adapter for HUB to 1/2x28

A HUB-to-1/2x28 direct thread adapter. HUB is the only mounting pattern on our shelf with real depth on both sides, so a HUB can keeps your options open if you change systems later.

Pros

  • ✓Deepest adapter shelf of any pattern we track
  • ✓Direct thread simplicity on a HUB can

Cons

  • ✗Single retailer at the moment
  • ✗You still buy one adapter per thread pitch
$71.69Check PriceDetails
Dead Air Armament Direct Thread Brake Mount .22 Caliber 1/2x28
The muzzle-side half of a QD system

Dead Air Armament Direct Thread Brake Mount .22 Caliber 1/2x28

A brake-style mount in .22 calibre 1/2x28. This is the purchase you repeat for every host you want the can to jump between, which is where QD stops being cheap.

Pros

  • ✓Multi-retailer, so it can be price-shopped
  • ✓Doubles as a muzzle device when the can is off

Cons

  • ✗One required per host
  • ✗Adds length ahead of the muzzle
$80.69Check PriceDetails
KAK Industry A2 Birdcage Flash Hider for AR-15 5.56 1/2x28
The price baseline (not a suppressor mount)

KAK Industry A2 Birdcage Flash Hider for AR-15 5.56 1/2x28

A plain A2 birdcage. Pinned here on purpose: it is what a muzzle device costs when it does not have to index a suppressor, and it is the number every QD mount above is really being compared against.

Pros

  • ✓Cheapest way to cover a threaded muzzle

Cons

  • ✗Will not mount a suppressor

So: pick the system before you pick the can, count your hosts honestly rather than aspirationally, confirm your thread pitch in writing, and prefer a shared pattern over a proprietary latch unless you are certain this is the only suppressor you will ever buy. Almost nobody is certain of that twice.

Frequently Asked Questions

Is direct thread or QD better for a first suppressor?+
If the can will live on one host, direct thread. It is fewer parts, less length, and the catalog prices it lower on both the adapter and the can itself. QD earns its cost once you are moving a single can between several threaded hosts often enough that unthreading a hot suppressor is the thing stopping you.
What is a HUB mount and is it worth paying for?+
HUB is a shared 1.375x24 rear thread that lets one can accept adapters from multiple makers rather than only its own. On our shelf it is the only pattern with real depth on both the can side and the adapter side, which makes it the practical hedge against buying into a system you later leave. HUB-labelled cans do sit higher in the catalog than direct-thread-labelled ones.
Can I use the same suppressor mount on two different thread pitches?+
No. A mount is cut for one pitch, and 1/2x28 and 5/8x24 are not interchangeable even though both are common. If your hosts use different pitches you buy one adapter per pitch, which is a real line item on a multi-host plan. Measure or confirm with the barrel maker before ordering anything.
Do suppressor mounts go on sale?+
Rarely, and not in a way worth waiting for. Suppressor hardware is thinly stocked across retailers and most listings sit at or very near their own recorded low, so there is neither much of a shopping spread nor much of a discount to wait for. Ammunition behaves the opposite way, which is where a price alert actually pays.
Does a suppressor mount need a tax stamp?+
Mounts, adapters, pistons and muzzle devices are ordinary parts and are not themselves the regulated item — the suppressor is. That said, suppressors are NFA items and both federal process and state legality change, so verify the current rules for your state and confirm with your dealer before you buy anything in this category.
Why are quick-detach suppressors more expensive than direct thread ones?+
Partly the hardware, but mostly the market segment. The cans that advertise a QD mount in our catalog cluster in the upper tiers, while the cheapest cans we track are almost all plain direct thread. So the price difference you see between the two is largely a difference in which models get sold each way, not a measurement of what the latch costs to make.
