Primary Weapons Systems PWS Body Buffer H4 – 4140 Steel, Black

Upgrade your AR-platform rifle with the Primary Weapons Systems (PWS) Body Buffer H4, engineered for reliable cycling and reduced recoil in demanding shooting applications. Constructed from durable 4140 steel with a hard black finish, this heavy H4-weight body buffer is built to withstand the rigors of high-volume shooting and enhanced pressure loads, making it an ideal choice for suppressed rifles, pistol-caliber carbines, or any build requiring a heavier buffer to tame excessive bolt carrier group velocity.

The H4 buffer weight provides the additional mass needed to slow the bolt carrier group’s rearward travel, promoting consistent lockup, reducing felt recoil, and minimizing bolt bounce for improved overall reliability. Whether you’re running a high-output gas system, a suppressor, or a non-standard caliber setup, this buffer delivers the performance and durability that serious shooters demand.

At Deep Roots Rifle Co, we carry a strong selection of AR components and buffer system accessories to support your custom builds and upgrades. Our knowledgeable staff is available to help you choose the right buffer weight for your specific gas system, barrel length, and ammunition combination.
