Product Description

The Geissele Maritime Bolt Catch is a warfighter-inspired, enhanced mil-spec replacement designed to fit any lower receiver that accepts a standard mil-spec M16/M4 carbine bolt catch. 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.

Note: A mil-spec bolt catch spring and plunger are required for assembly and are not included.

Product Highlights

  • Enhanced, increased surface area for quicker bolt lock-back and bolt release manipulation
  • Extended controls improve ergonomics and accessibility, especially for left-handed shooters
  • Aggressive checkering delivers a textured, non-slip feel with gloves or at night
  • Heat-treated 8620 steel construction for rugged, long-lasting service life
  • Manganese phosphate finish for corrosion resistance and mil-spec style durability
