Hey everyone. As a lot of you know, I really try to foster a sense of community and I work to support our local small businesses. Unfortunately unexpected tragedies strike us at the least expected times. Our friend Mr. Gray and his family unfortunately spent their New Year's taking account and trying to find shelter after a fire burned down their home. Despite this major setback - He is back out there running the food truck in these cold temperatures. If that doesn't scream resilience, I don't think I know the meaning of the word then. While he is out there working to cover expense, this economy is rough, and insurance isn't going to cover everything. If you can find it in your heart to patronize his business or donate, then I will pay it forward and discount your next purchase.

Thanks for everything and stay safe out there, especially you Gray's Wings & Things

Now that was NOT expected 😳🥹

These lucky guys beat the onslaught and got their silencers in under a day - The first approvals we've had under 0$ stamps. And this was on our standardized in house NFA trusts. Enjoy you guys!!

That said - Unfortunately this is kot the standard. This is more of a "one-off." Did you know more that 150,000 applications were received yesterday? That's more than the entirety of November 2025!!! So, again, please be patient with your poor "Silencer Guy," there is only so much vibes and manifesting can do 😔🙏

Happy New Year's 🎉The day has come and the 200$ tax is GONE 🙌

While this is joyous day and for many a historical day for the industry, it is certainly not a happy New Year's for my customers, and in turn for myself 😬The eForms submission is (Just as predicted) down and out for the count. Please have some patience for your local "Silencer Dude" - I'm keeping an eye on it and I will continue to get these submitted and off for approval as fast as they come. Also, please keep in mind has been behind on shipping due to the holidays and we are way behind on orders. I'll keep you all apprised directly as I work to resolve that. Until then, maybe be present with your family/loved ones? Or if you can't, go to the range/gym/small-business-of-choice? I don't know - I've got your mountains of paperwork to get through so I wouldn't know 🤷🏻

Oh! As promised - An update on Form 4 Trust Conversions. We are now ready to start accepting appointments to get your Individual approved Form 4s transferred to your trusts. Send a text and we will get you squared away (Hopefully soon 🤞).

🌟From our team to you and your family- Merry Christmas 🎄

It must certainly be a very special Christmas when we can get John to muster a genuine half-smile out of him! 😁 We want to recognize the incredible work John has done. His dedicatio. to the project has been instrumental in helping you guys get your transfers done ✔️ Thankfully Rise & Shine Bake Shop was open and came in clutch with the incredible baked goods. Seriously- The team over at Rise & Shine are among the best and their goodies* are 🤌👌

Anyways, back on topic. There are only a few days until we celebrate the end of $200 tax stamps. That said, that means we certainly have a busy time ahead at the beginning of the year. Having the ability to spend time with your loved ones is something that isn't guaranteed and should never be taken for granted. We will be taking some time to catch up on business tasks while spending time with our family's, as such we will not be starting new sales or transfers until the 2nd to allow us time to catch up on house keeping and be with our loved ones, so please understand 🖤 Have a great holiday and see you next year!

🎄❄️ The store is looking and feeling a bit festive, just in time for a good sale 🎁🔔

Right now we are in the final stretch of the year and prepping for a long day (or two or three 🫠) of silencer submissions on January 1st. With that priority we almost missed one of the biggest sales of the year: Desert Tech SRS and HTI 💪

Until Christmas any SRS or HTI purchased comes with a free case of match ammo and an extra magazine (And if you know how much match 338 LM, or God forbid - 50 BMG - costs, you would know how big of a deal this is). Also - Ignore the MSRP. I will throw in the military discount on top for all buyers.

Ever shot a 50 BMG that was as quiet as a silenced AR 15? An HTI paired with a Thunder Beast Ultra 50 will get you 0.5 MOA guaranteed rifle that puts some silenced 5.56 semi autos to shame. Not only that, but all models are multi caliber and carry a Return-To-Zero guarantee for changing barrels and calibers in the field in under 60 seconds. Come see why our PRS instructor Black Hammer Tacti-cool enjoys these rifles.

So rather than waiting around for 50 BMGs to get the final ban in this state, maybe it's time to get one of the lightest and most accurate 50 BMGs around before it's too late?

¯\_(ツ)_/¯

🚨🚨Last call for the January 1st preparation sale 🚨🚨

Tomorrow is the last day for significant savings (110 off the MAP) on B&T silencers, including:
1️⃣Print XH 556 Full Size and Sub Compact
2️⃣SRBS 762 Inconel and TI (TI is backordered)
3️⃣Vers 36 M
4️⃣Print X Ranger

All of these suppressors are great options for a low-backpressure silencer to reduce the wear and tear on your rifle and run without any modifications needed.

We are still running a discount (Albeit much smaller) on other in stock options until Christmas so get in now before our mad dash to get everyone submitted 😬

Drop me a text or message here today to get started!

Hey everyone, hope the holiday season is treating you well! A few important updates ❗

1️⃣ Last day for PAID tax stamp submission is 12/26/25. So if you were thinking of trying to get in before the flood, realistically we need to know by 12/21/25.

2️⃣ We realize that having a silencer in NFA jail just plain sucks. I get it 😒 Though that doesn't mean you shouldn't be able to use it in the mean time. Since we are located in Hole In The Wall, Kennewick after all, you might as well benefit from it. As of today we will be starting program where you can use your silencer at the range while you wait for approval. Details available at the range desk and upon request!

3️⃣Final call for paid-for-paid stamps (IE silencers where we pay the tax stamp for you and submit before December 26th to fast track approval) is December 15th. Options are slim right now, but they exist. Let us know if you are looking into any options!

Have a great week!

Hoping everyone had a relaxing Thanksgiving and was able to mentally and physically recharge from the normal commotions of life! 😌I know I did, and it's time to get back to it. So let's start fresh with another Black Friday week sale - SilencerCo Scythes🗡 Yes. These things are light, quiet, durable, and modular. Everything you need for your next hunt, range day, or precision shoot. We are cutting an even larger deal on these than the normal Black Friday sale. Unfortunately per Meta I can't post the price here 🙄Love it.

On a different note - Some of you have heard of and been to Wheat Head Brewing Co. and know the Miller's story. They have strived to turn their farm into a communal space with a great atmosphere and they have excelled in their goal. If that's your thing stop by some time. They even have some good non-alcoholic options. If you are a veteran, stop by and find a free drink on the wall from me (While it is still there 🤞). Have a great weekend regardless!

Happy Thanksgiving everyone 🍁 We are thankful for so much this year - The blessings we have had in our lives have been plentiful, and we are grateful. We also want to recognize our loved ones, our customers, and our partners: Hole In The Wall, Kennewick and Black Hammer Tacti-cool for all of their support 😁 Though I must say, I am not grateful for Meta. Apparently we are on Meta's naughty list and they refuse to recommend our posts to you due to their AI mistaking our posts for inappropriate behavior 🙄 Oh well.. But that won't dissuade us from letting you know we have a large Black Friday sale going occurring now! Can't share prices here, but reach out to the store by text and we will let you fill you in! Hoping to catch up with each of you soon! - Edward

Looks like Surefire is back at it for another shot at their additive-manufacturing (IE: 3D printed) versions of the legendary RC series. The Surefire RC4 is on the way, including a new mini version. Pre-orders are live and we we can easily get them and save them until January 1st. In other upcoming silencer news - The CAT Saigon Patrol (45 ACP modular handgun silencer) and CAT Kitty Kat (A 4.25" 5.56 silencer that beats many twice the length) are launching soon. We have some on the way, but these are definitely a pre-order needed now item as these get printed in small batches that don't match the large demand. Want to hear how good a CAT silencer sounds? Message me for a demo!

Just a heads up: Currently we are not accepting outside silencer transfers, I appreciate the understanding. Also don't forget - We have many silencers in stock now. And yes! We have started stocking, something that wouldn't have been possible without the support from all of you over the years. So a thank you to all of you for the continued support! - Edward

Hey everyone, long time. Figured I would wait to break the news until it was official, and it is finally official - We have opened a retail storefront at our partner's range inside Hole in the Wall in Kennewick. As we've grown over the years, we've learned many lessons along the way. We have outgrown our home based solution and decided it would be best for our community if we could expand and provide more services.

Not only have we decided to open the storefront, we have also brought along a new partner - Our good friend and resident military firearm enthusiast - John Tran. John's passion for training, shooting, and wealth of knowledge will be a great asset for both new and seasoned shooters and we are happy to have him with us. Let's welcome him and definitely never mention to him that 300 BO rounds have no business in a 5.56 rifle.

So what does the move bring to the table? Well, a few things. For one we have started to take consignments. New firearm sales and transfers are expanded as well. Currently NFA transfers from online are not accepted. Additionally we have also started silencer and firearm demonstrations where you can come in and try out select fi****ms and silencers. Over time the inventory will grow with select items both ourselves and customers recommend you have the opportunity to test out.

Speaking of silencers - Come January 1st the tax stamp goes from 200 to 0. That's right. 0. BUT - Don't wait. By December expect inventory to be scarce. So what to do in the mean time? Good question - If you want to wait until January 1st for the savings but don't want to be stuck waiting and run the risk of a state silencer ban, we can hold the can till January 1st! Simply message me and we will get it taken care of. As usual - I will always do my best to get you the product you want, not the one I want to sell. I take care of the process from beginning to end, you have my guarantee. Hence why we are the Elite partner for SilencerShop here in the region.

There is much more to come, but I think this is all for now. See you all soon!

-Edward and the rest of the team
