silencer saturday 414 aac legacy suppressors return kind of

Good afternoon, everyone, and welcome back to TFB’s Silencer Saturday, brought to you by Yankee Hill Machine, manufacturers of the new Victra-12 shotgun suppressor. This week, we're looking at the return* of some classic suppressors. While they bear the names of the originals, they also differ in some modern ways.

Silencer Saturday @ TFB:

SHOT Show 2026 is right around the corner! Both the TFB and TFBtv crews are heading to Las Vegas soon for show coverage. We will have articles on the blog, and videos hitting the TFBtv and TFBtv Show Time channels. Go subscribe to both of those channels so you won’t miss any of the new things hitting the market.

With SHOT Show magic in the air, the new product announcements are coming fast. We have seen several suppressors in the run up to the show, including the BANISH 556 and Bergara getting into the silencer game with the BTi-30 titanium suppressor. One of the original American suppressor names, Advanced Armament Corporation, aka AAC, is also revamping its line for 2026. It has been part of the Palmetto State Armory family for a few years, and the new models breathe new life into some well-known products.

M4-2000

The first new AAC suppressor is one of the oldest names in their catalog. The M4-2000 was one of the first modern, quick-detach rifle suppressors designed for use on the AR-15. It even had an NSN number assigned, and it saw use on military rifles.

While it was a strong contender back in the day, the state of the suppressor industry is far different now. The new M4-2000 keeps some styling that hearkens back to the original while updating the design to a modern standard. AAC’s new version is 3D-printed and made from inconel for hard use. That is a robust material, and additive manufacturing creates a single-piece body with no weld lines to fail. The updated M4-2000 is a reduced backpressure design, and it features a built-in front flash hider. That flash hider feature has some resemblance to the original AAC flash hider mounts. Compare it to the AAC logo, which is one of those flash hiders looking head-on.

One major change from the original is the mounting system. The 51T mount is gone, replaced by the 1x16 LH mounting system. This new system has left-hand threads and tapers that protect those threads from carbon buildup while centering the suppressor on the muzzle device. If you prefer to use a different mounting system, there are also HUB threads so the back end can adapt to a wide range on mounts.

The new M4-2000 is 1.63 inches in diameter and just over six inches long. It weighs 16.7 ounces without the HUB mount. It has a black DLC coating. And while it is a 5.56mm suppressor, it also accommodates 6mm ARC. AAC will begin shipping the M4-2000 in January.

300-BT

The 300-BT is a new silencer design focused on the .300 Blackout cartridge. While the silencer design is new, AAC originally pioneered the .300 Blackout cartridge, hence the actual SAAMI name of the cartridge as .300 AAC Blackout. Dedicating a suppressor to that chambering ties back to one of the company’s enduring products.

AAC’s 300-BT is a modular suppressor. In the long configuration, it is eight inches long, and weighs 12 ounces without a mount. The short configuration is 5.4 inches long and weighs five ounces. It manages these low weights thanks to full titanium construction, with a black DLC finish for longevity. AAC describes the design goal as getting .300 Blackout subs to be as quiet as possible, while also suppressing supersonic loads and even the occasional .308 Winchester round. Look for the 300-BT to hit the market in January.

7.62 SDN-6

Finally, we have the renewed 7.62 SDN-6. The SDN-6 shares design DNA with the revamped M4-2000. It too is a 3D-printed Inconel suppressor with an integrated flash hider, low backpressure design, and 1x16LH mount on a HUB system. This 30-caliber suppressor is seven inches long and weighs 20.5 ounces without a HUB mount.

Sabre Series

There are also some new Sabre silencers in the Palmetto State Armory family. The BT5 is an inconel, 3D printed suppressor with a helical internal structure. It is HUB threaded for mounting cross compatibility and includes a Plan B-style muzzle device and mount. These silencers are “powered by B&T,” hence the “BT” name designation. The BT5 is a 5.56mm can, and we may see other BT caliber options in the future as well.

There are four models in the current lineup. Both full-size and mini lengths are available, and black and FDE are offered colors. The full-size version is 7.1 inches long and weighs 16.4 ounces without the HUB mount. The shorty is 6.3 inches long and weighs 16.1 ounces without the HUB mount. All four models retail for $799 and are in stock as of writing, and free shipping is included!

We will be sure to get hands-on with all of these products at SHOT Show, and hopefully will be able to get pricing info on the AAC items as well. Thanks for stopping by, and we will see you here next week.
