Luth-AR Buffer Retainer with Spring – AR-15 (10-Pack)

The Luth-AR Buffer Retainer with Spring is a replacement component for AR-15 pattern rifles that secures the buffer inside the lower receiver when the upper is separated. This 10-pack provides spares for multiple builds or replacements for worn or lost retainers—a common occurrence during field stripping, maintenance, or parts installation. Each retainer includes its spring for complete functionality.

Machined from steel with a phosphate finish for corrosion resistance, these retainers are drop-in replacements requiring no gunsmithing. Installation is straightforward: insert the spring into the retainer hole in the lower receiver, compress with a punch, and slide the retainer into place. The 10-pack format is ideal for armorers, gunsmiths, or builders managing multiple AR platforms.
