The LBE Unlimited AR-15 front sight base kit is a complete, ready-to-install solution for builders and gunsmiths setting up an AR-platform rifle with iron sights. This kit bundles everything needed to mount a functional front sight to your upper receiver—no trips back to the parts bin for missing fasteners or springs. It's the kind of practical approach that saves time on the bench and gets your rifle running sooner.
The front sight base comes F-marked, a detail that matters if you're building or restoring a rifle with period-correct or mil-spec aesthetics. Whether you're assembling a new AR, replacing a damaged sight base, or setting up a backup iron sight system, having all the components in one kit eliminates the guesswork and the likelihood of mismatched or substandard parts.
LBE Unlimited has built a reputation for straightforward, no-frills AR-15 parts that work reliably in the field. This front sight base kit reflects that philosophy—quality manufacturing without the marketing markup, just the hardware and hardware know-how you need.
