Geissele Ultra Duty Mag Release Button 05-3634

The Geissele Ultra Duty Mag Release Button 05-3634 replaces a small, easy-to-overlook part with one that actually earns its spot on a duty or competition build. It's a direct mil-spec swap, so installation doesn't require any modification to the lower - just a button that does the job better.

Machined from stainless steel rather than stamped or cast like most stock components, it holds up to years of hard use without the wear points that eventually round off a standard button's edges. The checkered texture is the real functional upgrade here: it gives a thumb something to grip even with wet hands, gloves on, or blood in the mix, which is exactly the scenario a Geissele mag release is designed for. That same texture matches Geissele's Maritime Bolt Catch, so the two components read as a matched set rather than mismatched upgrades.

As an AR-15 mag release button, it drops straight into any mil-spec lower receiver with no fitting or machining required - pull the old mag release button pin, drop this one in, done.

Key Features:

• Machined from stainless steel
• Checkered texture for secure engagement in wet or gloved conditions
• Corrosion-resistant black finish
• Matches the texture of Geissele's Maritime Bolt Catch
• Direct mil-spec replacement, no modification needed
• Compatible with AR-15 and AR-10 platforms
• Included in Geissele's Super Duty and Ultra Duty Lower Parts Kits

This Geissele Ultra Duty Mag Release Button is a small part that changes how reloads feel under pressure - which is the whole point of upgrading it.
