Good afternoon suppressor super enthusiasts and welcome back to another edition of TFB’s Silencer Saturday. We’ve got a bit of a potpourri of NFA topics for you today, starting with NFA wait time updates, a look at some recent patent filings and a look at some new products announced over the past few weeks. As far as review items go, I’ve been shooting and enjoying the YHM Sidewinder pistol suppressors, including some magic with 40S&W through a 10mm GLOCK G29 – WITH THIS ONE WEIRD TRICK. We’ll get into that whole topic outside of our regular Silencer Saturday content.

SILENCER SATURDAY #92: NFA Wait Time Updates – Patents – Products

First up: NFA wait time updates.

NFA tracker is probably the most comprehensive set of data outside the actual NFA registry, even though users submit unofficial dates and information. Let’s call it crowdsourced crown pleasing data. Current Form 4 paper forms approval times are still bumping up against 10-12 months. Unfortunately, there is still no process to use the ATF Efile System Form 4 applications. Rumors are still pointing to sometime in 2020 for ATF’s new electronic filing system. I’m done making predictions at this point – the NFA application process is a ruthless, dark quagmire – like crossing the Hades rivers when entering the underworld. Maybe that’s a bit dramatic.

My most recent Forms 4s were submitted in August of 2018 and approved in the middle of September 2019. (They would have been faster if I hadn’t forgotten to sign them the first time around – again).

But EForms are available for Form 1 submissions. My most recent submission was August 23, 2019 and approved September 26, 2019. That period of time included the Labor Day weekend holiday, so I’d estimate the current wait time at about 30 days.

The NFA buying process has to be one of the must frustrating aspects of the gun world. Not only do you have to ask permission to trim your barrel from 16.1 inches to 15.75 inches, but you have to pay for the right as well. And then, to top it off, there’s a tedious paperwork process that includes submitting photographs and fingerprints (that most likely just sit in a file cabinet) with an undetermined wait time that can be anywhere from 30 days to over a year. But, I’m preaching to the choir.

USPTO – Recent Filings:

About once a quarter I take a trip through the USPT.gov for anything noteworthy regarding silencers. Here are some recent additions.

Patent: Modular Firearm Sound Suppressor – SIG Sauer

Examples include a threaded coupler for connecting two portions of a firearm sound suppressor housing together. The threaded coupler includes a sound suppressing baffle. Using the coupler and its integrated baffle provides additional sound suppression compared to sound suppressors with other types of connectors between housing portions.

Design Patent: Suppressor Heat Shield Assembly

CLAIM The ornamental design for a suppressor heat shield assembly, as shown and described.

Patent: Modular Firearm Suppressor

A modular suppressor kit includes a modular suppressor and suppressor tool. The modular suppressor includes a barrel attachment portion that has a central passage. The barrel attachment portion is configured to attach to a firearm barrel. The modular suppressor includes a cap portion that has a central passage. The modular suppressor includes a body portion that has an internal baffle structure and an expansion chamber. The body portion is attachable to, and separable from, the barrel attachment portion and the cap portion. The body portion defines a central passage that is alignable with the central passage of the barrel attachment portion and the central passage of the cap portion. The suppressor tool has an engagement feature for engaging with at least one of the barrel attachment portion, cap portion, and body portion.

 

Patent: Firearm having an integral recoil booster and compensator, and quick detach suppressor system

A firearm having an integral recoil booster including a pair of bushings and spring positioned to interact with an integral firearm compensator; a quick detach mount for one or more suppressor baffles; and one or more suppression baffles. As configured, the integral recoil booster also generates additional force ensuring contact at a slide/barrel interface. A monolithic suppressor may also be used with the quick detach mount.

 

Patent: A Suppressor For A Firearm

A suppressor for a firearm includes a casing having rear and front ends. Baffles are inside the casing between the rear and front ends. A cylindrical support has an upstream end, a downstream end, and a circumferential rib. The upstream end is connected to the rear end of the casing. The downstream end is engaged with at least one of the baffles. The circumferential rib surrounds the cylindrical support between the upstream and downstream ends and extends radially from the cylindrical support to the casing. Upstream and downstream annular chambers defined at least in part by the casing, the cylindrical support, and the circumferential rib circumferentially surround the cylindrical support. A plurality of apertures through the cylindrical support provide fluid communication through the cylindrical support to the upstream and downstream annular chambers.

New And Noteworthy Products

We have just exited the dry season when it comes to new firearm releases. Between now and the end of the year we can expect a monsoon of new product announcements. Hopefully that includes silencers and silencer accessories as well. Here’s a few recent additions that might get you attention.
