About this model

generic chamber safety flag, originally designed to fit ar15/10 Its been a while since i printed and used one of these and realized a few issues i had with the original design. WIth V2, Ive beefed up the leg and added a small nub to the back to help keep it in place when the bolt is pushed forward on a semi auto. Also ive moved the word, "CLEAR" out further to make it more visible when an accessory is installed. Enjoy www.applied-kinetics.com
