The KRYTAC Compact Carbine Stock (CCS) is now available as a separate part/accessory for those who want a replacement or use it for a custom gun project... "The KRYTAC Compact Carbine Stock, known as the CCS, is a two position stock that can extend and collapse with the push of a single button to fit any situation. Its unique design also allows for the accommodation of a small battery in the buffer tube, allowing you to keep your rifle streamlined without the use of a battery box or other external battery option.

The CCS installs directly to the back of your standard M4 Style AEG replacing the standard buffer tube assembly and stock. In its most compact position, it is ideal for short rifles and PDW set ups in CQB environments, but can be extended to its full length to provide a stable platform."
