Key Features & Benefits

All-in-one value: Purchasing the kit is more cost-effective than buying components separately and reduces the risk of mismatched parts.
Durability for range use: Materials and finishes chosen for abrasion and wear resistance so your stock maintains its appearance and performance over frequent use.
Low-profile, classic styling: Subtle, functional design integrates cleanly with modern optics and accessories without adding bulk.
Ideal Uses
Building a new AR-15 from the ground up.
Replacing damaged or worn rear stock components.
Restoring a rifle to mil-spec configuration.

Compatibility & Fitment
This kit is designed specifically to fit AR-15 style rifles using mil-spec diameter receiver extensions (buffer tubes). It is compatible with standard mil-spec components and most mil-spec stocks available on the market. If your upper/receiver or stock uses a commercial (non-mil) diameter tube, this kit will not be a direct fit — verify your receiver extension diameter prior to purchase.

LBE Unlimited selects components that meet industry tolerances and finish standards. Each kit is inspected for completeness and packaging integrity so you receive ready-to-use parts straight from the box. The included hardware (castle nut and lock plate) conforms to standard dimensions used by armorers and gunsmiths.
