Cobalt’s Universal Billet AR-15 Stock provides superior balance, ergonomics, and Cobalt’s signature aggressive visual appeal. Cobalt’s engineers have gone to great effort to develop a stock that enhances control and handling characteristics of your rifle. The stock’s length of pull and drop at the heel have been optimized to enhance ergonomics and comfort; while the overall weight shifts a rifle’s balance point closer to the shooter to speed transitions and reduce arm fatigue. We machine our stocks from solid ¬†aluminum billet then finish them in armor black cerakote.


The Universal Billet Stock will fit all standard rifle length receiver extensions and matches up cleanly to all forged and most billet receiver types. Our stock includes mounting screw and does not require the A2 spacer.
