This is the Sliding Stock used on almost all Carbine models during the Vietnam War and into the late 1970's. Initially they were Anodized Aluminum - and later coated in a Vinyl Black coating that was prone to chipping.

* This page is for the Stock only. If you would like the full Assembly (Here)



  •  Anodized, Grey in Color
  •  Black Coated (only comes in semi-gloss)



  • The first few collapsing stock examples were handmade prototypes and somewhat complicated in design. We hope to offer these soon.
  • This was eventually replaced in 1966 with a much simpler sliding stock design made of aluminum - this is the product you are looking at now.
  • Eventually the Aluminum stock was replaced by a same shaped version in much lighter polymer (Here)
  • This design was then used up until replacement by the M4 version, which introduced the stock design still used today.

    Excellent product. As close to the real deal as you can find. Retro is a great company to deal with.

    Black Coated Aluminum

    My dad has an original CAR-15 that he bought when he was a teenager and he always bragged about the aluminum stock he had and how light weight it all was. Well I saw this and bought it, and he couldn’t tell the difference between the two. Defiantly worth the money for a retro rifle and the wait for shipping wasn’t long at all. Great stock will buy from Retro Rifles again!
