Lantac BC-Pro Upgrade Bolt Catch Black

The LanTac BC-Pro Upgrade Bolt Catch in black is a precision-engineered replacement bolt catch designed for AR-platform rifles requiring enhanced manipulation and durability in high-round-count or demanding operational environments. Machined from 17-4 PH precipitation-hardened stainless steel and treated to AMS2753D specification via QPQ nitride processing, this bolt catch delivers superior corrosion resistance and extended service life compared to standard MIM or investment-cast alternatives.

The BC-Pro features an enlarged, aggressively textured paddle that improves tactile feedback and control during manipulations, particularly beneficial during speed reloads or one-handed charging. Reinforced geometry around the pivot hole increases structural strength, reducing stress concentration in a high-wear area. The QPQ nitride coating provides hardened surface protection without compromising the underlying stainless steel substrate, making this bolt catch suitable for corrosive environments including salt-air exposure and adverse weather conditions. CNC precision manufacturing ensures tight tolerances and reliable fit across AR variants without requiring modifications to the receiver.

This upgrade is targeted at competitive shooters, precision rifle operators, and AR builders prioritizing component longevity and tactile performance. Units logging high-volume training cycles benefit most from the reinforced pivot design and stainless construction. Law enforcement and military-adjacent users operating in corrosive climates will appreciate the nitride treatment's resistance to rust and saltwater degradation, making this bolt catch suitable for extended patrol cycles or permanent field deployment without frequent maintenance intervals.

LanTac's commitment to full CNC machining and premium surface treatment positions the BC-Pro as a mid-tier upgrade within the bolt catch category, bridging the gap between OEM cast parts and ultra-premium billet alternatives. The textured paddle geometry reflects lessons learned from high-volume shooter feedback, making this a data-driven refinement rather than cosmetic modification.
