Description

These stock adapters allow ACR folding adjustable stocks to be installed on Swiss Arms/SIG SG550* series rifles. The adapters are 3D printed out of a high strength carbon fibre reinforced nylon material that closely matches the mechanical properties, appearance, and texture of the stock.

A significant ergonomic improvement over the standard folding stock, the ACR stock provides a better cheek weld when using optics as well as a 7-position adjustable length of pull. The firearm may still be fired while the stock is folded.

They can be purchased either as the adapter alone, or pre-installed on an ACR folding stock (all original hardware will be included).

A 3/16″ punch is required for installation.

*Please note: These adapters were originally designed to be used with Swiss-made stamped steel SG550 series lower receivers. They will also fit the US-made 551A1 aluminum lower receiver. Some modification may be necessary to fit these to a 556 series rifle.
