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.

    Have one on a .223 wylde build and another on a 6.5 Creedmoor build. Super lightweight, super rigid and rugged and super sexy. Plus, they’re not unreasonably expensive. Great part for a custom build.

  2. Rated 5 out of 5


    Great Stock! Easy to install on my Palmetto State Armory PA10 Gen 2 lower. Used a standard DPMS A2 buffer tube and buffer set up. Installed easily and looks great on my 6.5 Creedmoor.
