LBE Unlimited Mil-Spec Carbine Buffer Spring – ARSPRG
The LBE Unlimited Mil-Spec Carbine Buffer Spring (ARSPRG) is a high-quality, essential component for any 2026-spec AR-15 build or maintenance cycle. While often overlooked, the buffer spring is the "heartbeat" of the rifle’s cycling system, and the ARSPRG is engineered to provide consistent, reliable tension over thousands of rounds. Unlike standard music wire springs that can lose their elasticity over time, LBE Unlimited utilizes 17-7 Stainless Steel. This high-performance material offers superior corrosion resistance and exceptional fatigue life, ensuring that your rifle maintains proper bolt velocity and timing even in harsh environments or under heavy-duty usage.
Designed as a direct drop-in replacement for any standard MIL-SPEC carbine-length receiver extension (buffer tube), the ARSPRG (765857617343) provides the exact compression rates required for 5.56 NATO and .223 Remington platforms. By choosing a spring made from 17-7 stainless, shooters benefit from a smoother recoil impulse and reduced "spring twang" compared to lower-grade alternatives. Proudly Made in the USA, LBE Unlimited continues to be a go-to source for professional builders and armorers who demand American-made reliability in their critical internal components.
