Lantac BC-PRO Upgrade AR-15 Bolt Catch

The Lantac BC-PRO Upgrade is a replacement bolt catch for AR-15 lower receivers. It has an enlarged paddle with aggressive grip texture and reinforced geometry around the pivot hole, which makes the control easier to manipulate and adds strength at the pivot.

The part is precision CNC machined from 17-4 PH precipitation-hardened stainless steel in H900 condition and finished with QPQ nitride treatment to AMS2753D specification for corrosion resistance. It is not investment cast or MIM. The package includes a roll pin.

A mil-spec bolt catch spring and plunger are required for installation and are not included. Compatibility with other billet AR-15 receivers is unknown. The manufacturer states it functions with Forged Receiver sets and Raven and Onyx receiver sets.
