Made in USA
- The first few collapsing Buttstock examples were handmade prototypes and somewhat complicated in design.
- 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 above 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.
*** NOTE: Raw and Anodized versions ship immediately. "Coated" version can take 1-6 weeks delivery time since the coating is performed in scheduled runs.
