The Hero Arms XTRAXN Keymod Rail Handguard looks very similar to the LaRue rail system Chris Costa runs with on his AR except there are quite a few alterations made to make it their own style.
For example, this is a Keymod system already covered with rail panels with a familiar looking pattern. What you don't see everyday is the QD rail system. This means that you'll be able to remove this handguard and quickly slip one on of a different length or the same length with different accessories applied.
This is something you don't see every day in the airsoft world and the great thing is that you'll be able to apply it to AEG as well as GBBRs. Hero Arms have not missed a beat when it comes to diversity
