LBE Unlimited ARPSR Front Sight Post with Spring and Retainer AR-Platform Black

The LBE Unlimited ARPSR is a direct-replacement AR-15 A2-style front sight post built for builders and gunsmiths servicing standard A2 front sight bases on the AR-15 / AR-platform. This complete service kit includes the sight post, sight post spring, and spring retainer, so you have every small component needed to swap a worn, lost, or damaged post in one go without chasing down missing hardware.

Constructed from durable steel with a corrosion-resistant black finish, the ARPSR installs into the standard A2 front sight base just like the factory part. It is sized and finished to Mil-Spec dimensions for a proper fit and consistent sight picture on any A2-configured AR front sight tower.

Whether you're completing a fresh build, repairing a stripped post, or building out a parts bench, the LBE Unlimited ARPSR front sight post kit delivers the three small parts you need in a single, inexpensive package.
