LE stock design as seen used by US military forces on their M4 rifles (also seen in movie SWAT). Durable ABS plastic design and full multi-position settings for greater comfort than the standard stock design. Includes metal rear sling mount.
NOTE:Requires some minor modification work on receptor part on Marui M4 / M16 series guns. There is a small groove in the stock tube that is a bit narrower than the Marui receptor tube. You need to take a small file to narrow down the Marui receptor tube before you can fit this onto your gun. The required work will be obvious when you put the two parts together.
