Full Details:

4.6 oz H2 Buffer Weight:
This AR-15 H2 buffer provides a 4.6-ounce operating weight, making it heavier than a typical standard carbine buffer while remaining lighter than many H3 configurations. The additional reciprocating mass can help slow bolt carrier group movement and provide more controlled cycling in compatible AR-15 rifles and pistols.

Precision-Machined Steel Construction:
The H2 heavy buffer features a precision-machined steel body designed for durability and repeated use. Its robust construction makes it suitable for AR-15 owners looking for a dependable carbine buffer for general-purpose builds, suppressed configurations, and reliability tuning.

Single Sliding Weight Design:
This 4.6 oz AR-15 buffer uses a single sliding internal weight. The moving internal mass helps manage movement within the buffer system while providing the additional weight associated with an H2 carbine buffer configuration.

AR-15 Carbine Compatibility:
Measuring approximately 3.25 inches in length, this H2 carbine buffer is designed for compatible AR-15 carbine-length receiver extensions and standard carbine buffer springs. It installs as a direct replacement for a compatible carbine buffer without requiring modification to the buffer tube.

Over-Gassed and Suppressed Configurations:
The increased mass of a 4.6-ounce H2 buffer can be useful in AR-15 configurations that cycle more aggressively than desired, including many over-gassed rifles, short-barreled configurations, pistol builds, and suppressed firearms. Slowing bolt carrier velocity can help create a smoother operating cycle and more controlled ejection characteristics.

Why Choose an H2 Heavy Buffer?

An H2 buffer provides additional reciprocating mass compared with a standard carbine buffer without moving all the way to a heavier H3 configuration. This makes the AR-15 H2 heavy buffer a popular intermediate buffer weight for shooters who want to tune cycling characteristics while maintaining versatility across a wide range of AR-15 builds.

The heavier 4.6 oz buffer can help slow rearward bolt carrier movement, reduce excessive cycling speed, and minimize bolt bounce in appropriately configured rifles. Shooters may also experience smoother cycling, reduced muzzle movement, and more consistent ejection compared with lighter buffer configurations.

Why Choose a 4.6 oz AR-15 Carbine Buffer?

Balanced H2 Buffer Weight:
At 4.6 ounces, this H2 carbine buffer provides more mass than a standard approximately 3-ounce carbine buffer while remaining a versatile option for AR-15 owners who do not require the additional weight of an H3 buffer.

Carbine-Length Design:
The 3.25-inch carbine-length buffer is designed to fit compatible collapsible-stock receiver extensions and standard AR-15 carbine buffer systems.

Versatile AR-15 Tuning Option:
An H2 recoil buffer can be useful across a variety of AR-15 configurations, including carbine-gas and mid-length-gas rifles, short-barreled setups, suppressed firearms, and other builds that may benefit from additional buffer mass.

Common AR-15 H2 Buffer Applications

Carbine and Mid-Length Gas Systems:
The H2 buffer can be used as a tuning option in compatible AR-15 rifles equipped with carbine-length or mid-length gas systems.

Short-Barreled Rifles and AR Pistols:
Short-barreled AR-15 configurations and pistol builds can sometimes benefit from the additional reciprocating mass provided by a heavier carbine buffer.

Suppressed AR-15 Platforms:
Suppressor use can increase operating pressure and bolt carrier velocity in some AR-15 configurations. An H2 heavy buffer is commonly selected when additional buffer mass is desired for suppressed shooting.

General Reliability Tuning:
The 4.6 oz H2 buffer provides a straightforward option for shooters tuning bolt carrier speed, ejection characteristics, and overall cycling behavior in compatible AR-15 platforms.

FAQs

What is an AR-15 H2 buffer?

An AR-15 H2 buffer is a heavier carbine-length buffer used to increase reciprocating mass within the AR-15 operating system. This model weighs 4.6 ounces and is designed for compatible carbine-length receiver extensions and buffer springs.

How much does this H2 buffer weigh?

This AR-15 H2 heavy buffer weighs 4.6 ounces, placing it above the weight of a typical standard carbine buffer while remaining lighter than many H3 buffer configurations.

How long is this AR-15 carbine buffer?

This H2 carbine buffer measures approximately 3.25 inches in length and is designed for compatible AR-15 carbine-length buffer tubes.

Will this H2 buffer fit an AR-15 carbine buffer tube?

Yes. The 4.6 oz H2 buffer is designed for compatible AR-15 carbine receiver extensions and works with standard carbine-length AR-15 buffer springs.

What is the difference between an H2 buffer and a standard carbine buffer?

An H2 buffer contains more mass than a typical standard carbine buffer. This additional buffer weight can slow bolt carrier velocity and change the cycling characteristics of the AR-15 operating system.

What is the difference between an H2 and H3 buffer?

An H2 buffer generally provides less reciprocating mass than an H3 buffer. The 4.6-ounce H2 buffer serves as a versatile middle-ground option for shooters who want more buffer weight than a standard carbine configuration without moving to a heavier H3 setup.

Can an H2 buffer be used with a suppressed AR-15?

An H2 buffer is commonly used in suppressed AR-15 configurations that benefit from additional reciprocating mass. Suppressor use can increase gas pressure and bolt carrier velocity in some rifles, making a heavier buffer useful for tuning the operating cycle.

Can an H2 buffer help an over-gassed AR-15?

The additional mass of an H2 heavy buffer can slow bolt carrier velocity and may help tune the cycling characteristics of an over-gassed AR-15. Buffer weight should be matched to the complete firearm configuration, including barrel length, gas system, ammunition, suppressor use, and other operating components.

Can this H2 buffer be used with 5.56 NATO and .223 Remington?

Yes. This AR-15 H2 carbine buffer is designed for compatible AR-15 platforms, including common 5.56 NATO and .223 Remington rifle and pistol configurations.

Is an H2 buffer good for a short-barreled AR-15?

An H2 buffer is commonly selected for short-barreled AR-15 rifles and pistol configurations that benefit from additional buffer mass. The proper buffer weight depends on the individual firearm's gas system, barrel length, ammunition, and operating characteristics.
