The CQB36 kit is comprised of a foregrip, magazine, and carrying handle. A stock is not include. An 8-10" barrel is recommended for use with the foregrip, perfect for you operators that enjoy a very compact close quarters "CQB" marker.
Our kits are modded from existing airsoft parts that we purchase from airsoft stores. They are a combination of existing Tippmann X7 parts as well as airsoft parts that we modify to allow them to be useable on your X7.
The Scenario Arms Scenario Arms X7 CQB36 Kit is newer, so it should be commonly available, both new and used.
