CQB buffer tube stock

this is a CQB stock for an airsoft m4. It has 3 adjustable settings which you can change with a screw for running and gunning or using it like a brace. this is my second version meaning it has a rounded off back with grooves which allow more grip when braced. it is a fairly good friction fit on the buffer tube to where you may be able to get away with not using the screw. be sure to run tree supports as they may be slightly difficult to get out.
