Sig Sauer T300BLK194ME-20 300 Blackout 194gr Subsonic Tactical Ammo - 20 Rounds

The Sig Sauer 300 Blackout 194gr subsonic tactical ammo is purpose-built for shooters running suppressed rifles or seeking subsonic performance in the .300 Blackout platform. Loaded with a 194-grain projectile, this round stays subsonic across a wide range of barrel lengths, making it ideal for both hearing-safe shooting and tactical applications where velocity control matters. The Lehigh Defense maximum expansion boat-tail hollow point projectile is engineered for consistent terminal performance, combining controlled expansion with deep penetration on target.

Subsonic .300 Blackout ammunition has become the go-to choice for AR-15 shooters running suppressors, offering the same external ballistics and handling as standard supersonic loads while eliminating the supersonic crack. Sig Sauer's tactical load pairs modern bullet design with consistent quality control, giving you reliability you can count on whether you're training, hunting, or running a precision rifle system.

Each box contains 20 rounds, making it convenient for range trips, training sessions, or ammunition rotation. Built to Sig Sauer's standards and loaded with proven Lehigh Defense projectiles, this is serious ammo for serious shooters.

Frequently Asked Questions

Is this ammo subsonic in all barrel lengths?

Yes, the 194-grain load is designed to remain subsonic across standard .300 Blackout barrel lengths when fired from typical AR-15 upper receivers.

What is this ammo best used for?

Subsonic .300 Blackout ammo excels in suppressed rifle systems, tactical training, and applications where you need velocity control. It's also popular for hunting where hearing-safe performance and consistent ballistics are priorities.

Can I use this in a standard AR-15?

Yes, .300 Blackout fires in any AR-15 upper receiver chambered for that caliber. The subsonic load simply delivers lower velocity than supersonic variants, making it perfect for suppressor use.

What makes the Lehigh Defense projectile different?

Lehigh Defense's maximum expansion hollow point is designed to balance controlled expansion with penetration, using a boat-tail design for aerodynamic efficiency and consistent performance at subsonic velocities.
