The AR 300 Blackout price depends on whether you are shopping for a complete rifle, an upper receiver, or ammunition. Complete entry level rifles from budget friendly brands typically cost between $500.00 and $800.00. Mid range rifles and premium upper receiver groups range from $800.00 to $1,600.00, while high end boutique platforms can easily exceed $2,500.00. The cost of ammunition is also a major factor, with typical prices ranging from $0.50 to $1.70 per round. Building your own rifle using a stripped lower and a complete upper receiver often provides the best value.

300 Blackout Ammo Price
| 300 Blackout Load | Bullet Weight | Box Size | Price | Price Per Round |
| Bulk FMJ Practice | 147 grain | 50 | $25.00 | $0.50 |
| Standard Supersonic | 150 grain | 20 | $15.94 | $0.79 |
| Subsonic Target | 220 grain | 20 | $26.00 | $1.30 |

Based on current retail listings, the lowest price found for getting into the platform is a basic Palmetto State Armory upper receiver for $250.00, allowing you to attach it to an existing AR-15 lower. Complete budget rifles from brands like Rossi or Bear Creek Arsenal start around $277.00 to $400.00. High end platforms like Q LLC’s Honey Badger represent the upper spectrum, routinely selling above $2,000.00.
For ammunition, the lowest current price is roughly $0.50 per round for bulk practice ammunition. Premium defensive and hunting loads can cost upwards of $1.70 per round. The median price per round across all load types sits at $1.35.
Prices vary based on components, brand reputation, and whether the firearm utilizes a standard direct impingement gas system or a specialized short stroke piston system. Ammunition prices fluctuate based on bullet weight, as heavy 220 grain subsonic bullets require more raw materials than standard 110 grain supersonic projectiles.
How Much Does AR 300 Blackout Cost?
Your total cost depends on your approach. Buying a complete, factory built rifle from a mid tier manufacturer like Aero Precision or Bravo Company will cost between $1,000.00 and $1,600.00. However, because the 300 Blackout shares the same bolt carrier group, magazines, and lower receiver as the 5.56 NATO, you can simply purchase a complete upper receiver for $250.00 to $850.00 and snap it onto an existing AR-15 lower.
300 Blackout Ammo Price Per Round
Because the cartridge is designed to perform in two distinct ways, the price per round varies significantly by type.
- Bulk Supersonic Practice: $0.50 to $0.80 per round.
- Subsonic Target: $1.00 to $1.35 per round.
- Premium Defensive and Hunting: $1.50 to $1.70+ per round.
Shooting subsonic ammunition suppressed is the primary appeal of the caliber, but those heavy, slow moving bullets are noticeably more expensive to shoot than lightweight supersonic target loads.
AR 300 Blackout New vs Used Price
Because the AR-15 market is highly saturated, buying used can save you a substantial amount of money.
- Standard budget rifles often lose 20% to 30% of their retail value on the used market.
- High end platforms like Daniel Defense or Q LLC hold their value exceptionally well, with used models often selling within a few hundred dollars of their new MSRP.
If you are buying a used upper receiver, always inspect the gas system and barrel, as heavy suppressed use can lead to excessive carbon buildup.
AR 300 Blackout Price Compared With 5.56 NATO
Since both calibers share the same platform, the primary ongoing cost difference is the ammunition.
| Product/Cartridge | Example | Box/Retail Price | Price Per Round If Applicable |
| 300 Blackout | Subsonic Target 220 gr | $27.00 | $1.35 |
| 5.56 NATO | Federal American Eagle 55 gr | $12.99 | $0.65 |
| .308 Winchester | Federal Power-Shok 150 gr | $25.99 | $1.30 |
| 7.62x39mm | Belom Tactical 123 gr | $11.00 | $0.55 |
While hardware costs are identical, 300 Blackout ammunition is consistently more expensive than 5.56 NATO or steel cased 7.62x39mm due to the heavy bullets and specialized powders required for reliable subsonic cycling.
What Affects The Price?
Several variables dictate what you will pay at checkout.
- Subsonic vs Supersonic: Subsonic loads use bullets that are twice as heavy as supersonic loads, requiring more raw lead and copper.
- Barrel Length and Quality: Cold hammer forged barrels cost significantly more than standard nitride barrels, but offer better durability.
- Gas System: Standard direct impingement systems are cheap and reliable. Advanced short stroke piston systems designed to run cleanly with suppressors add massive cost to the firearm.
- Brand Prestige: Companies known for extreme quality control and military contracts charge a premium for their upper receivers and complete rifles.
Availability
The 300 Blackout is one of the most popular alternative AR-15 calibers on the market. Rifles, complete uppers, barrels, and ammunition are heavily stocked by virtually all major online retailers and local gun shops. While prices spiked dramatically in the past, current supply chains are robust, and availability is excellent.
