Inside the 57th Day of Silence: A Complete Suppressed .300 Blackout Build
Inside the 57th Day of Silence: A Complete Suppressed .300 Blackout Build
The 57th Day of Silence is the undisputed heavyweight of Silencer Central’s 100 Days of Silence campaign, a fully loaded, ready-to-run suppressed .300 Blackout system worth $5,329.83 handed to a single winner.. One free entry on Friday, June 12, 2026 puts ten prizes in a single winner’s hands: a titanium suppressor, the rifle built around it, the subsonic ammunition that feeds it quiet, a 10mm sidearm, glass, two blades, a $500 carry credit, and the gear to keep all of it running.
On the 57th day of Silence, we’re not just handing out another rifle . We’re giving away a complete suppressed 300 Blackout build that was purpose-built from the ground up around the cartridge itself. We The rifle, the suppressor, the optics, and even the ammunition, was chosen specifically because we could giveaway the ultimate platform for true quiet performance. By anchoring the entire giveaway on 300 Blackout, we created a turn-key system that delivers movie-like suppression right out of the box. The giveaway includes a premium Bergara B-14 Bolt Action, A Leupold scope thanks to Gunprime.com, a top-tier user-serviceable suppressor, and a generous supply of factory subsonic ammo so the winner can start shooting quietly the moment they open the case.
The History of 300 Blackout and Supersonic vs. Subsonic Loads
The .300 AAC Blackout was born in the late 2000s when Advanced Armament Corporation (AAC) developed it specifically for U.S. special operations forces. They needed a cartridge that could deliver .30-caliber terminal performance from existing AR-15/M4 platforms. Especially from short barrels, while offering reliable subsonic operation for suppressed use. By necking up the 5.56×45 case to accept 30 caliber bullets and optimizing the shoulder geometry, AAC created a round that cycles flawlessly in standard AR-15 magazines and bolts while maintaining the same overall length as 5.56. It was officially standardized as the .300 AAC Blackout in 2011 and has since become the gold standard for quiet, compact rifle builds.
What truly sets 300 Blackout apart is its dual-personality nature. Supersonic loads (typically 110–150 grain bullets) scream out of the muzzle at 2,000+ fps, delivering rifle-like energy, flat trajectories, and excellent performance out to 300+ yards, perfect for general plinking, hunting, or defensive work where raw power matters. On the other hand subsonic loads (180–220+ grain bullets) are intentionally throttled to stay below the speed of sound (~1,060 fps), eliminating the sharp sonic crack entirely. When paired with a quality suppressor, subsonic 300 Blackout becomes dramatically quieter than almost any other rifle cartridge, producing the kind of near-silent report that defines “day of silence” shooting.
The BANISH 30 V2 Suppressor: Quiet Performance Perfected
The BANISH 30 V2 from BANISH Suppressors (available through Silencer Central) is a premium, 100% titanium modular .30-caliber suppressor designed for maximum versatility and real-world performance. Available in two quick-change configurations including a compact 6.4-inch short setup with 8 baffles (just 9.5 oz) or the full 8.17-inch length with 11 baffles (12.4 oz). It delivers outstanding sound reduction while staying lightweight enough for serious field use. Its industry-standard HUB mount, 5/8×24 threading, and user-serviceable CAN-CLEAN™ design let you break it down for easy cleaning without special tools. Rated from .17 HMR all the way up to .300 Weatherby Magnum and limited full-auto rated, the Banish 30 V2 is one of the most adaptable cans on the market. In testing on .308 it achieves an impressive 34.5 dB reduction at the shooter’s ear; on subsonic loads it gets even quieter, often dropping reports to true hearing-safe levels without ear protection.
That’s exactly why the Banish 30 V2 is the perfect suppressor for the Winchester Super Suppressed 300 Blackout 200-grain OTM (SUP300BLK) load we’re including in the giveaway. Winchester engineered this subsonic round specifically for suppressed use. Utilizing clean-burning powder, encapsulated base to cut lead fouling, and a deliberate 1,060 fps velocity that stays reliably subsonic even from longer barrels. Paired with the Banish 30 V2, the combo produces near-silent, Hollywood-quiet shots with minimal carbon buildup and negligible recoil. It also pairs beautifully with the Bergara B-14 Stoke rifle that rounds out this complete suppressed build. The B-14 Stoke’s factory-threaded 5/8×24 muzzle and lightweight, accurate bolt-action platform turn the Banish 30 V2 into a natural hunting companion. Whether you run it in the short configuration for maneuverability or the full-length tube for maximum suppression. The result is a balanced, sub-7-pound suppressed rig that delivers pinpoint accuracy and movie-like quiet on every shot, making Day 57 of Silence the ultimate turn-key quiet rifle package.
The rifle: Bergara B-14 Stoke
The Bergara B-14 Stoke (SKU B14S9511) is a purpose-built compact bolt-action rifle chambered in .300 Blackout, designed from the ground up for lightweight portability and exceptional accuracy. Weighing just 6.0 pounds with a 16.5-inch 4140 CrMo barrel (No. 4.5 taper, 1:8 twist rate) and an overall length of only 35 inches, it delivers Bergara’s renowned sub-MOA guarantee right out of the box. The rifle features a smooth, improved Remington 700-style push-feed action, a Graphite Black Cerakote finish for rugged durability, and a sporter-style synthetic stock optimized for smaller-statured shooters with a comfortable 12.25-inch length of pull. It ships with an AICS-compatible detachable box magazine (6-round capacity) and a factory-threaded 5/8×24 muzzle, making it suppressor-ready right out of the box. Built in Spain with Bergara’s precision barrel-making expertise, the B-14 Stoke is the ideal platform for hunters, backcountry shooters, or anyone who wants a quiet, maneuverable bolt gun that feels custom without the custom price.
This rifle pairs perfectly with the Winchester Super Suppressed 200-grain OTM subsonic .300 Blackout ammunition (SUP300BLK) and the Banish 30 V2 suppressor that complete the Day 57 giveaway build. The short 16.5-inch barrel keeps subsonic velocities reliably around 1,060 fps for maximum quiet performance, while the clean-burning powder and encapsulated bullet base in the Winchester load minimize fouling in both the rifle and can. Thread the Banish 30 V2 directly onto the muzzle (HUB-compatible and user-serviceable), and the entire rig transforms into a balanced, sub-7-pound suppressed system that delivers near-silent shots with zero sonic crack and minimal recoil. Whether you’re running subsonic loads for stealthy close-range hunting or plinking, or swapping in supersonic ammunition for longer-range versatility, the B-14 Stoke, Winchester Super Suppressed ammo, and Banish 30 V2 create a turn-key quiet rifle that’s as capable in the field as it is enjoyable at the range. Day 57 just handed you the ultimate compact suppressed 300 Blackout package.
Winchester Super Suppressed .300 Blackout 200 Grain (SUP300BLK): The Quiet Heart of the Build
Winchester’s Super Suppressed 200-grain Open Tip Match (SUP300BLK) is purpose-engineered subsonic ammunition that turns the .300 Blackout platform into a true stealth rifle. Loaded to a deliberate 1,060 fps muzzle velocity from a 16.5-inch barrel, this round stays reliably subsonic even in longer barrels, eliminating the sonic crack entirely while delivering 499 ft-lbs of energy at the muzzle. More than enough for ethical close-to-medium range hunting or precise plinking. The clean-burning powder, copper-encapsulated bullet base, and lead-free primer design dramatically reduce carbon and lead fouling in both the barrel and suppressor, keeping the system running cleaner and quieter longer than most factory subsonic loads. Accuracy is excellent (sub-2-inch groups at 100 yards are common), recoil is soft and controllable, and it feeds and functions flawlessly in both bolt-action and semi-auto platforms. Paired with the Bergara B-14 Stoke and the Banish 30 V2 suppressor in the Day 57 giveaway, the Winchester Super Suppressed load creates a perfectly balanced, near-silent suppressed rifle that requires zero additional tuning. The factory-threaded muzzle accepts the Banish 30 V2 instantly, and the ammo’s low-fouling formula keeps the modular titanium can performing at peak suppression for hundreds of rounds between cleanings. Whether you’re slipping through the woods on a quiet hog hunt or enjoying ear-safe plinking at the range, this ammunition is the final piece that makes the entire suppressed 300 Blackout build live up to its “Day of Silence” name—Hollywood-quiet performance straight from the factory box.

The blades: WE Knife Inceptus and CIVIVI Iron Tide
Two knives ride in this build, from two independent brands with two different philosophies. The WE Knife Inceptus pairs a premium M390 powder-stainless blade with a titanium handle — a built-to-last folder for the carrier who wants long stretches between sharpenings and strong corrosion resistance. The CIVIVI Iron Tide runs a tough, easy-to-sharpen 14C28N Sandvik blade in a rugged work folder that punches well above its cost. They’re two separate choices, each best for a different priority — carry whichever fits your hand, or both.
Best for: the Inceptus suits the carrier who prioritizes premium build and edge life; the Iron Tide suits the carrier who wants a tough, value-driven everyday blade.
The logbook: Armorer Pro membership
Rounding out the build is a one-year Armorer Pro membership ($49.99) — an app for logging round counts, maintenance, and load data so the winner always knows where each firearm sits in its service life. On a build with this many moving parts, it’s how the whole setup stays maintained instead of guessed at.
Best for: the shooter who’d rather track round counts and service intervals than find out the hard way.

Is a suppressor legal where you live?
Two separate questions decide it, and people constantly blend them. Owning a suppressor is legal under federal law and in all but a handful of states; civilian suppressor ownership is currently prohibited in California, Delaware, Hawaii, Illinois, Massachusetts, New Jersey, New York, Rhode Island, and the District of Columbia. Hunting with one is set separately by each state’s wildlife agency — and as of June 2026, suppressor hunting is legal in 40 of the 42 states that allow ownership, with Connecticut and Vermont allowing ownership but restricting hunting use. The trend has run one direction for a decade, driven by the American Suppressor Association and partners, but the rule that protects you is simple: confirm both ownership and hunting use for your state before you act. (The giveaway’s own eligibility reflects these restrictions — see the rules below.)
Frequently asked questions
What is in the Day 57 100 Days of Silence giveaway?
A complete suppressed .300 Blackout build: a BANISH 30-V2 suppressor, a Bergara B-14 Stoke rifle, 100 rounds of Winchester Super Suppressed subsonic ammunition, a Kimber 1911 DS Warrior in 10mm, a $500 Crossbreed Holsters credit, a Leupold VX-Freedom 3-9×50 scope, a Wilson Combat Shooter’s Kit, WE Knife and CIVIVI folders, and an Armorer Pro membership — $5,329.83 total, to one winner.
How do I enter the 57th Day of Silence?
Entry is free at PopularSuppressors.com on Friday, June 12, 2026, from 6:00 a.m. to 10:00 p.m. Central Time, with the winner posted that evening. No purchase necessary. Each day’s giveaway requires its own separate entry.
Who can enter, and which states are excluded?
Open to U.S. legal residents 21 and older. The giveaway is void in NY, FL, CA, and RI; the suppressor prize is additionally void in CA, DE, HI, IL, MA, NJ, NY, RI, and DC. See the official rules for full details.
Is there still a $200 tax stamp on the suppressor?
No. The $200 federal tax stamp was eliminated as of January 1, 2026. The ATF Form 4 approval process still applies, but Silencer Central handles the paperwork for the winner and delivers the approved suppressor directly to their door.
Why is the build based on .300 Blackout instead of 5.56?
Because .300 Blackout delivers full .30-caliber performance from a short barrel, where 5.56 loses efficiency, and because it runs exceptionally well suppressed and subsonic. That makes it the better cartridge for a compact, quiet, do-everything rifle.
What’s the difference between subsonic and supersonic .300 Blackout?
Subsonic loads (around 190–220 grains) stay below the speed of sound for the quietest suppressed shooting, at the cost of range and a steep trajectory. Supersonic loads (around 110–135 grains) fly flatter and hit harder at distance but produce a ballistic crack no suppressor can remove. Many shooters keep both.
Can the winner hunt with this suppressor?
In most states, yes — suppressor hunting is legal in 40 of the 42 states that allow ownership as of June 2026 (Connecticut and Vermont restrict hunting use). Confirm your state’s wildlife-agency rules for the species and season before hunting suppressed.
Is the Winchester ammunition a hunting load?
No — the included Winchester Super Suppressed is a 200-grain subsonic range and practice load (an Open Tip Range bullet). It’s ideal for confirming zero and high-volume practice; for hunting, pair the rifle with a subsonic load designed to expand on game.
