Vltor A5 H2 Stainless Buffer 7.97 Oz

The Vltor A5 H2 Stainless Buffer is a precision-engineered recoil buffer designed for AR-pattern rifles that demand tuned, predictable action. At 7.97 ounces, this H2-weight stainless buffer slots into the A5 system—a purpose-built alternative to mil-spec configurations that lets you dial in your rifle's cycling characteristics for cleaner operation, faster lock times, and reduced wear on critical components. Whether you're running a piston gun, suppressed rifle, or a standard direct-impingement setup, the right buffer weight makes a measurable difference in reliability and felt recoil.

Vltor Weapon Systems engineered the A5 ecosystem around modularity and precision. The stainless construction of this H2 buffer resists corrosion and maintains consistent performance across temperature and humidity swings—critical if your rifle sees field use, suppressed fire, or extended training cycles. Pairing the buffer with a quality A5 tube and the right spring lets you optimize your rifle's dwell time and bolt carrier velocity, resulting in smoother operation and less punishment on your lower receiver and bolt.

Choosing the right buffer weight depends on your specific setup: piston guns, suppressors, and short-barreled uppers all shift the balance differently. The H2 sits in the middle-heavy range, making it a solid choice for suppressed or piston-driven builds, or for shooters running standard ammunition through heavier-recoiling configurations. If you're already running an A5 tube, swapping buffers is quick and gives you real-world tuning without guesswork.

Frequently Asked Questions

What buffer weight do I need for my AR-15?

Buffer weight depends on your rifle's configuration. The H2 is heavier than a standard H or carbine buffer, making it suitable for suppressed builds, piston systems, or rifles that cycle too fast. If you're unsure, consult your upper receiver or gas system manufacturer, or test across weights if you're already running an A5 system.

Is the Vltor A5 H2 compatible with standard mil-spec tubes?

No. The A5 H2 buffer is designed specifically for A5 receiver extensions. It will not fit standard mil-spec carbine tubes. Ensure your lower receiver is fitted with an A5 extension before purchasing.

Why choose stainless steel for a buffer?

Stainless resists corrosion and maintains finish and performance in wet, humid, or suppressed-fire environments. It's a straightforward durability upgrade, especially if your rifle sees field or training use.
