Each suppressor should be purpose driven to complement your mission set. As with everything there is a give and take. These rifles are setup specifically for Sniper team competitions. Running suppressed allows for the team to communicate while on the clock.
The thunderbeast Magnus RR not only suppresses the sound signature, but it mitigates around 30% of the recoil on this already soft shooting 6.5.
The Hux suppressor reduces the sound signature on this Seekins SP10 while also mitigating gas blowback into the system which allows this large frame gas gun to run with perfect reliability when seconds matter.

Over the barrel suppressors like this otter creek have several advantages.
1. Reduced overall length added while maintaining great sound suppression
2. Multiple index points allow for consistent mounting and minimizes POI shift
3. They look incredible

Running suppressed is crucial while working as a team. This allows your team to stay focused on the task at hand rather than fighting concussion and sound signature. Regardless of your use case, working suppressed makes situational awareness and the flow of information easier.

Manhattan Project is proud to be a part of the first introduction to long range hosted by our friends at Black Hammer. This one day class will be a fantastic way to dip your toes into long range shooting.

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!

*Except the American "cheese" - sorry Annelee 🫶😜

🚨🚨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!

-Edward
