Lantac Bc-pro Upgrade Bolt Catch

The LanTac BC-PRO Upgrade Bolt Catch is a precision-machined AR-15 replacement component engineered to improve both control and longevity in your rifle. Built from 17-4 PH stainless steel in H900 condition and finished with QPQ nitride treatment to military specification (AMS2753D), this bolt catch delivers the corrosion resistance and durability you need in a hard-use rifle. Unlike investment-cast or MIM alternatives, the BC-PRO is fully CNC machined, which means tighter tolerances and stronger geometry where it matters most—around the pivot hole area that sees real stress during operation.

The tactile upgrade is immediate: an aggressive grip texture and enlarged paddle make the bolt catch easier to manipulate under gloved conditions or in low-light situations. The reinforced supporting geometry adds strength without bulk, so you get a noticeable improvement in control without redesigning your lower receiver. LanTac backs the BC-PRO with US manufacturing, and it's proven compatible with forged AR-15 receiver sets and Raven Onyx billet receivers.

Installation is straightforward if you're replacing an existing mil-spec bolt catch—the BC-PRO accepts standard mil-spec springs and plungers (not included). Take care when removing the old catch to preserve those small parts; you'll need them for the new one. The roll pin comes with the BC-PRO. Note that compatibility with other billet upper and lower receiver brands is not guaranteed, so verify fit if you're running non-standard receivers.

Frequently Asked Questions

What do I need to install the LanTac BC-PRO bolt catch?

The BC-PRO comes with the catch itself and a roll pin. You'll also need a mil-spec bolt catch spring and plunger to complete the assembly. If you're upgrading from a standard mil-spec catch, carefully remove your existing bolt catch to save those spring and plunger components—they work with the BC-PRO and are not included separately.

Is the BC-PRO compatible with my AR-15 lower receiver?

The BC-PRO is confirmed compatible with forged AR-15 receiver sets and Raven Onyx billet receivers. Compatibility with other billet receiver brands is unknown, so we recommend verifying fit with your specific receiver before purchase or installation.

How does the BC-PRO differ from a standard mil-spec bolt catch?

The BC-PRO is precision CNC machined from premium stainless steel and finished with a military-spec nitride treatment for superior corrosion resistance. It features an aggressive grip texture and enlarged paddle for easier manipulation, especially with gloves, and reinforced geometry around the pivot hole for increased strength. Unlike many alternatives, it uses no investment casting or metal injection molding—it's fully machined.

Is the LanTac BC-PRO made in the USA?

Yes. The BC-PRO is manufactured in the United States.
