Dark Storm Industries DS-15 4.5 oz Carbine Buffer H2 – AR-15 Recoil Buffer

Description

Dark Storm Industries DS-15 4.5 oz Carbine Buffer H2 is precision-machined to deliver reliable recoil management and consistent cycling in AR-15 carbine-length buffer systems. Designed for shooters seeking smoother operation and improved control, this H2 buffer helps balance bolt velocity while reducing felt recoil during rapid or sustained fire.

Dark Storm Industries DS-15 4.5 oz Carbine Buffer H2 is constructed with a 416 stainless steel machined body and internal 4140 steel dead-blow weights, the buffer is engineered for durability and long service life. EPDM weight spacers and a high-durometer blue polyurethane bumper work together to minimize internal impact and reduce wear on critical components. The engraved face clearly identifies buffer weight for easy system tuning.

Proudly manufactured in the USA, the DS-15 H2 Carbine Buffer is an ideal upgrade for AR-15 rifles running carbine-length gas systems, offering dependable performance for training, duty, and recreational shooting.

Dark Storm Industries DS-15 4.5 oz Carbine Buffer H2 Specifications & Compatibility

The Dark Storm Industries DS-15 4.5 oz Carbine Buffer H2 is precision-machined from a 416 stainless steel body and internally weighted with 4140 steel dead-blow weights for controlled bolt movement and reduced recoil impulse. EPDM weight spacers and a high-durometer blue polyurethane bumper help minimize internal impact, reduce noise, and extend component life. The buffer face is engraved to clearly identify weight for easy system tuning and maintenance.

Compatibility

This H2 carbine buffer is designed for use in AR-15 platforms equipped with carbine-length buffer systems. It is compatible with standard AR-15 lower receivers and mil-spec carbine buffer tubes. The increased mass of the H2 buffer makes it especially well-suited for rifles with carbine or mid-length gas systems, helping to slow bolt speed, improve reliability, and reduce felt recoil.

• Compatible Platforms: AR-15

• Buffer System Length: Carbine

• Gas Systems: Carbine-length and mid-length

• Caliber Compatibility: .223 Remington / 5.56 NATO and similar AR-15 calibers

• Buffer Tube: Mil-Spec Carbine Receiver Extension

• Not Compatible With: Rifle-length buffer systems

Pro Tip

An H2 buffer is commonly used to improve reliability in AR-15 builds running higher gas pressure, suppressed setups, or full-mass bolt carrier groups by reducing bolt speed and smoothing the recoil cycle.
