Advanced Armament Remington Subsonic 300 AAC Blackout Ammunition 220 Grain Open Tip Flat Base - S300AAC4

The Advanced Armament Remington Subsonic 300 AAC Blackout 220 Grain Open Tip Flat Base (S300AAC4) is engineered for quiet and accurate suppressed shooting, making it an excellent choice for tactical applications, target shooting, and precision training. This subsonic ammunition is designed to provide reliable cycling and reduced sound signature when paired with a suppressor, without compromising accuracy or terminal performance.

Featuring a 220-grain Open Tip Flat Base (OTFB) bullet, this round is optimized for stability at subsonic velocities, ensuring tight groupings and minimal flight deviation. The muzzle velocity of 1,050 fps keeps the projectile below the speed of sound, significantly reducing sonic crack and making it an ideal option for stealth applications.

Encased in high-quality brass casings with a Boxer primer, this round is non-corrosive and reloadable, offering excellent longevity and versatility for shooters who prefer to hand-load their own ammunition. While it is specifically designed for suppressed firearms, it also delivers smooth cycling and reliable feeding in both bolt-action and semi-automatic rifles chambered in 300 AAC Blackout.

For shooters looking for maximum sound suppression, consistent performance, and precision accuracy, Remington Subsonic 300 AAC Blackout delivers a stealthy, reliable, and high-performance experience in suppressed and unsuppressed platforms alike.

Features and Specifications:

  • Compatibility: Designed specifically for 300 AAC Blackout firearms, optimizing performance in suppressed shooting environments.
  • Performance Metrics: With a muzzle velocity of 1,050 fps and an impressive 538 ft-lbs of muzzle energy, this ammunition is suited for controlled, subsonic engagement.
  • Noise Reduction: The subsonic nature of this round minimizes noise, making it ideal for tactical training and recreational shooting where stealth is paramount.
  • Bullet Design: The Open Tip Flat Base improves accuracy by stabilizing the flight of the bullet, essential for consistent target acquisition.
  • Packaging Options: Available in bulk purchasing options that include free shipping, facilitating cost-effective acquisition for frequent use.

Deep Dive

Overview

The Remington Subsonic 300 AAC Blackout Ammunition is tailored for enthusiasts and professionals who seek effective, quiet performance. Its subsonic qualities make it particularly valuable for suppressed shooting, ensuring that shooters can remain discreet while maintaining a high level of accuracy and impact. Whether for recreational target shooting or tactical training, this ammunition provides shooters with the confidence to utilize it in noise-sensitive environments.

History and Development

Emerging from the united expertise of Remington and Advanced Armament Corp, the 300 AAC Blackout caliber was developed to offer versatility similar to the M4 Carbine, even when fired through short barrels. The subsonic variant, particularly this 220 Grain ammunition, harnesses advancements in ballistics technology to deliver considerable power without compromises in silence, meeting the specialized demands of modern shooters.

Why It Stands Out:

Advanced Armament Corporation was originally founded in 1994 in Lawrenceville, GA, and has become one of the industry leaders in gun suppression. Acquired by Remington/Freedom Group in 2009, AAC continued production in Georgia until 2014, when manufacturing was consolidated at the Remington Outdoor Company facility in Huntsville, AL. However, before that relocation, they essentially hit the suppressor jackpot in 2010 when the U.S. Army awarded them the contract for the XM2010 sniper rifle system, including the Titan QD .338LM suppressor. And let’s not forget the invention of .300 Blackout ammo that same year AAC has been responsible for numerous innovations with regard to sound suppressor development, among them interchangeable pistons to allow suppressors to be exchanged among firearms with different barrel thread patterns, fast-attach rifle suppressors, and the use of lightweight alloys such as titanium.
