Advanced Technology Intl AR15 Bolt & Washer Kit for AR15 Grip Screw - High-Performance, Durable Components
- Firearm Group:
- AR Platform
The ATI Outdoors AR15 bolt and washer kit for AR15 grip screw gives you a solid upgrade over the frustrating flat-head factory screw that ships on most AR builds. This kit includes a steel hex-head bolt and a star washer—straightforward, durable components that make your grip assembly more secure and easier to work with. Whether you're finishing a new build or replacing a worn OEM screw on an existing rifle, this is the kind of small upgrade that saves you headaches at the range or in the field.
The hex-head design is a game-changer if you've ever fought with a stripped or slipping flat-head screw. You get solid tool engagement, less risk of marring, and the ability to actually tighten it properly without fear of camming out. The steel star washer distributes pressure evenly across the grip panel, which helps prevent the screw from loosening under recoil and wear.
Made in the USA, this kit is built to last and designed to work with standard AR-15 platforms. It's the kind of no-nonsense component that belongs in any builder's parts bin—cheap insurance against the minor frustrations that add up fast when you're running a modern rifle.
