LayLax 4" Outer Barrel Base For M4 AEG

This is a 4" outer barrel made in japan and machined to a very high standard, it is designed for those wishing to install aftermarket / free float hand guards.

The concept is that you buy the 4" base, then buy the size extensions you need to bring your outer barrel to the end of the rail or further depending on the custom look you are trying to achieve.

In order to remove the original barrel you will need a wrench tool.

Please use the o rings provided to prevent them being over tightened together.
