Sons of Liberty Gun Works MK1 Maritime Billet Stainless Bolt Catch with XP Spring & Plunger SOLGW-MK1-BOLTCATCH-KIT

The Sons of Liberty Gun Works MK1 Maritime Billet Stainless Bolt Catch is a precision-machined, corrosion-resistant upgrade to one of the most frequently manipulated components on the AR-15 platform, engineered specifically for environments where moisture, salt water, and harsh conditions demand a higher standard of material performance than standard mil-spec alternatives can provide. Machined from billet stainless steel, the MK1 Maritime Bolt Catch delivers exceptional corrosion resistance and surface hardness that outlasts standard steel or aluminum bolt catches in wet and maritime operating environments, while the billet construction ensures tighter tolerances and a more refined fit and finish compared to cast or MIM components. The included XP spring and plunger provide an enhanced engagement feel with positive, reliable actuation that improves upon the standard bolt catch spring kit, ensuring consistent and dependable bolt hold-open and release function across high round count use. A purpose-built and durable upgrade for AR-15 owners and builders who operate in maritime, coastal, or high-humidity environments and demand the highest level of corrosion resistance and component quality from every part of their rifle.
