Aero Precision H3 Carbine Buffer 5.6 oz - Buffer

Reduce felt recoil and improve cycling reliability with the Aero Precision H3 Carbine Buffer 5.6 oz. This heavier buffer slows bolt carrier velocity, helping tame over-gassed systems and deliver smoother, more controlled shooting.

The Aero Precision H3 Carbine Buffer 5.6 oz is a carbine-length buffer designed for AR-15 platforms using carbine receiver extensions.

Heavier mass slows bolt carrier velocity for reduced felt recoil and less bolt bounce.

Increases dwell time, improving extraction reliability in over-gassed or suppressed setups.

Direct drop-in replacement for standard carbine buffers with no modifications required.

• Type: H3 Heavy Carbine Buffer
• Weight Class: H3
• Weight: 5.6 oz.
• Length: 3.25"

Compatible with AR-15 and AR-10 platforms using Mil-Spec or commercial carbine-length receiver extensions. Also fits 8" GI-spec AR-10/AR-308 receiver extensions.

Precision machined to mil-spec dimensions for reliable fit and consistent performance. Built from durable materials to withstand years of regular use.

Ideal for suppressed builds, short-barreled rifles, and over-gassed systems where additional buffer mass improves reliability and control.

Aero Precision is known for applying aerospace-grade manufacturing standards to AR-15 components, delivering precision-built parts trusted by military, law enforcement, and civilian shooters alike.
