Explaining The Table
Based on live retailer data, the lowest current price found for a 20 round box of .300 Blackout ammo is roughly $16.00 for basic supersonic full metal jacket rounds. The highest current price found in the table is $3,700.00 for the premium Q Honey Badger SD integrally suppressed short barreled rifle.
The typical retail price for an average box of range ammunition hovers around $17.00 to $20.00. When looking at firearms, a standard .300 Blackout rifle typically retails for around $700.00. Comparing MSRP to actual retail price shows that both bulk ammunition and entry level rifles usually sell significantly below the manufacturer’s suggested retail price.
Different ammunition loads cost different amounts because heavy 200 grain subsonic bullets require more raw lead and specialized gunpowders to cycle properly at low speeds. In terms of firearms, the most expensive configurations are short barreled pistols and rifles from premium tactical brands that feature specialized buffer systems and factory included suppressors.
How Much Does .300 Blackout Ammo Cost?
If you want to purchase .300 Blackout ammunition, expect to spend an absolute minimum of $0.60 to $0.70 per round for budget supersonic loads. A standard 20 round box will cost $15 to $18 at most retailers. For shooters running suppressors, heavy subsonic ammunition is slightly more expensive, usually starting at $0.80 per round and capping out around $1.50 per round for premium expanding hunting ammunition.
.300 Blackout Price By Ammunition Type
The .300 Blackout caliber is uniquely split into two distinct categories of ammunition, each bearing different price points.
- Supersonic Ammunition: Generally firing lighter bullets weighing between 110 and 150 grains. These are the most affordable rounds to shoot. A standard 20 round box retails from $15 to $18, making the cost per round roughly $0.60 to $0.80.
- Subsonic Ammunition: Firing heavy bullets weighing 190 to 220 grains meant to travel slower than the speed of sound. These cost more due to the heavier projectiles. A 20 round box typically retails from $18 to $25, pushing the cost per round to $0.80 to $1.50.
.300 Blackout Rifle and Pistol Price
Because the .300 Blackout cartridge was designed to use the exact same magazines and bolt carrier groups as standard 5.56 NATO AR-15 rifles, the firearms themselves are relatively affordable.
- Entry Level Rifles and Pistols:Brands like Palmetto State Armory and Diamondback Firearms offer complete .300 Blackout rifles and AR pistols starting around $499 to $733.
- Mid Tier Firearms:Upgraded rifles from companies like CMMG or Aero Precision usually retail between $1,200 and $1,699.
- Premium Tier Firearms:High end, purpose built compact weapons like the Daniel Defense DDM4 PDW or the SIG MCX range in price from $1,800 to over $2,500.
.300 Blackout MSRP vs Retail Price
Ammunition manufacturers consistently list MSRPs that are 20 to 30 percent higher than the true street price. A box of Magtech 123 grain FMJ has an MSRP of roughly $25.00 but can easily be found at retail for $16.00. Similarly, a 1000 round case of subsonic ammunition might list an MSRP near $900.00, but online bulk retailers regularly sell it for $747.00 to $799.00.
For firearms, standard AR-15s chambered in .300 Blackout also sell below MSRP. However, highly sought after premium models like the Q Honey Badger often sell exactly at MSRP due to high demand and limited production runs.
Why Is .300 Blackout So Expensive?
While the firearms are priced identically to standard AR-15s, the ammunition is notoriously expensive. The high price tag of the cartridge is driven by a lack of military surplus availability and the high material cost of the bullets.
A standard 5.56 NATO bullet weighs 55 grains. A .300 Blackout subsonic bullet weighs 220 grains, meaning it takes exactly four times as much lead and copper jacket material to manufacture a single projectile. Furthermore, the specialized powders required to make heavy bullets cycle an AR-15 action reliably without breaking the sound barrier add to the overall manufacturing cost.
Used .300 Blackout Firearm Price
Buying a used .300 Blackout upper receiver or complete rifle is a great way to save money. Because AR-15 parts are highly interchangeable, many shooters sell their lightly used .300 Blackout components for steep discounts.
| Condition | Typical Price Range | Notes |
| New (Complete Firearms) | $499 to $3,700 | Price depends entirely on brand tier and setup |
| Used Good Condition | $350 to $800 | Budget brands and home built AR assemblies |
| Used Excellent Condition | $800 to $1,500 | Factory complete mid tier to premium models |
| Military Surplus | N/A | Cartridge does not have a cheap surplus market |
Note: Used market figures are estimated market observations based on secondary sales rather than official pricing.
.300 Blackout Price Compared With Other Calibers
Because .300 Blackout is heavily compared to other intermediate rifle cartridges, it is important to see how the ammunition pricing stacks up against the competition.
| Caliber | Typical Price Per Round | Price Difference |
| .300 Blackout | $0.60 to $1.50 | N/A |
| 5.56 NATO | $0.40 to $0.60 | .300 BLK is $0.20 to $0.90 more expensive |
| 7.62x39mm | $0.45 to $0.65 | .300 BLK is $0.15 to $0.85 more expensive |
| 9mm Luger | $0.20 to $0.35 | .300 BLK is $0.40 to $1.15 more expensive |
What Affects The Price?
Several critical factors influence how much you will pay for .300 Blackout products:
- Ammunition Type: Subsonic rounds with heavy 200 grain bullets cost significantly more than lighter 123 grain supersonic rounds.
- Purchase Volume: Buying single 20 round boxes is the most expensive way to shoot. Purchasing bulk 1000 round cases drops the price per round significantly.
- Firearm Brand: An entry level Diamondback AR-15 costs roughly $700, while a specialized Daniel Defense pistol costs nearly $2,000.
- Retailer: Local gun shops tend to have higher prices on specialty ammunition, while online bulk distributors offer aggressive discounts.
.300 Blackout Price Pros
- Cheap Firearm Conversions: Because it shares the same bolt carrier group and magazines as a 5.56 NATO AR-15, you can convert an existing rifle to .300 Blackout simply by buying a new barrel or upper receiver for $200 to $400.
- Excellent Suppressed Performance: It is arguably the best centerfire rifle cartridge for shooting quietly, offering massive performance gains over suppressed 9mm platforms.
- Growing Availability: The popularity of the round means ammo is heavily stocked at nearly every major retailer, driving prices down slowly over time.
.300 Blackout Price Cons
- High Ammo Cost: Even the cheapest supersonic training rounds cost 20 to 30 cents more per trigger pull than standard 5.56 NATO ammunition.
- Expensive Subsonics: If you bought the platform specifically to shoot quietly, feeding it a steady diet of heavy subsonic ammo will drain your wallet quickly.
- No Cheap Surplus: Unlike 5.56 or 7.62×39, there are no massive shipping containers of cheap military surplus ammunition entering the commercial market to drive the price floor down.
