The Meprolight Fiber-Tritium Bullseye rear sight (part no. 0631213108) is built for S&W M&P Shield, Shield Plus, and M&P 2.0 pistols, excluding the Shield EZ. Instead of aligning a separate front and rear sight, it aligns on a single central point of focus, giving it the feel of a red dot in a fully mechanical package.

A fiber-optic element gathers ambient light for daytime use, while premium-grade tritium takes over after dark. The sight is drop- and shock-rated for heavy recoil, and its low-profile, snag-free design draws cleanly from a holster.

Frequently Asked Questions

Does this sight fit the M&P Shield EZ? No. Meprolight specifically excludes the Shield EZ from this fitment; it is built for the Shield, Shield Plus, and M&P 2.0 instead.

Is this a single-dot or two-sight design? It uses a single central point of focus in the rear sight for a red-dot-like sight picture rather than a traditional two-sight alignment.

Does this sight need batteries? No. It combines a fiber-optic element for daytime brightness with tritium for night illumination, and neither requires batteries.
