E4 bolt

[challenger]

I picked up a MSAR E4 earlier this week and want to change to a left hand bolt. Is there a difference between the factory bolt and a Ratworx bolt? Haven't been able to get a hold of the manufacturer but I read that they'll swap bolts with me, anyone know if this is true?

The Ratworx hybrid bolt utilizes the AR15 small bolt parts like the pins, springs, ejectors and extractors. The MSAR ones utilize MSAR bolt parts.
