Good fit into the ar15 handle - ATI Outdoors AR-15/AR-10 Pistol Grip Screw w/ Star Lock Washer

I used this on my first AR build. I used a combination of top brands for the build and the Hogue pistol grip did not come with a grip screw. I've taken it off and on several times and it fits perfectly. The hex has not been damaged with the loosening and tightening.
