Luth-AR .223 Carbine Buffer Spring – AR-15 Carbine Buffer Tubes

The Luth-AR .223 Carbine Buffer Spring is a direct replacement for worn or damaged buffer springs in AR-15 carbine-length buffer systems. Buffer springs wear out over time, losing tension and causing short-stroking, ejection issues, or increased bolt carrier velocity. This spring restores reliable cycling and proper timing in your direct impingement AR-15.

Made from heat-treated chrome silicon steel with a corrosion-resistant finish, this spring is built for durability. Installation is drop-in simple—no gunsmithing required. Just remove the buffer and replace the spring. Compatible with standard mil-spec carbine buffer tubes and buffers.
