Spike's Buffer Tube Assembly Rifle

The Spike's Buffer Tube Assembly Rifle kit is a mil-spec buffer system designed for AR-pattern rifle builds requiring reliable bolt carrier group control and recoil management. This complete assembly includes the heavy-duty ST-T2 buffer, six-position mil-spec buffer tube, buffer spring, end plate, and castle nut—everything needed for a functional receiver extension system on intermediate-caliber carbines and rifles.

The six-position adjustable buffer tube allows shooters to optimize length of pull across different shooting positions and body armor configurations, a critical feature for duty weapons, training platforms, and precision rifle setups. The ST-T2 heavy buffer mitigates excess carrier velocity, reducing wear on critical bolt components and improving reliability in suppressed and unsuppressed configurations. The mil-spec castle nut and end plate ensure positive lockup and prevent accidental disassembly during operation or maintenance.

This buffer tube assembly serves law enforcement agencies, military units, competition shooters, and civilian rifle builders who require quality components engineered to military specifications. Whether building a new rifle, upgrading a tired system, or replacing damaged receiver extension components, the Spike's Buffer Tube Assembly Rifle provides proven reliability without compromise. The black finish resists corrosion in field conditions and meets standard mil-spec aesthetics.

Spike's Tactical maintains a strong reputation for producing AR-15 components that meet or exceed military standards. This buffer tube assembly is compatible with any AR-pattern rifle using standard mil-spec receivers, making it a versatile choice for 5.56 NATO, .223 Remington, and other intermediate-caliber platforms.
