Its increased surface area and extended controls make it faster and easier to lock the bolt to the rear or release it after a magazine change. The aggressive checkering provides confident, tactile feedback for positive manipulation with gloves or in low-light conditions, and the extended controls improve accessibility for left-handed shooters without breaking grip. Built from properly heat-treated 8620 steel and finished with a manganese phosphate coating, it is engineered for durability and dependable performance on the AR-15 \/ M16 \/ M4 platform.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e A mil-spec bolt catch spring and plunger are required for assembly and are not included.\u003c\/p\u003e\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEnhanced, increased surface area for quicker bolt lock-back and bolt release manipulation\u003c\/li\u003e\n\u003cli\u003eExtended controls improve ergonomics and accessibility, especially for left-handed shooters\u003c\/li\u003e\n\u003cli\u003eAggressive checkering delivers a textured, non-slip feel with gloves or at night\u003c\/li\u003e\n\u003cli\u003eHeat-treated 8620 steel construction for rugged, long-lasting service life\u003c\/li\u003e\n\u003cli\u003eManganese phosphate finish for corrosion resistance and mil-spec style durability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecs\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Geissele Automatics\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Bolt Catch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Mil-spec M16\/M4 carbine bolt catch platforms (AR-15 \/ M16 \/ M4 style lowers)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 8620 Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Manganese Phosphate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSurface Texture:\u003c\/strong\u003e Textured \/ Checkered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApprox.
