What are the different bolts for the MCX series?
I traded for a legacy and was told it is updated and it has the Gieslle trigger adapted and said bolt was updated also. How do I know if i have the right bolt to used a new 300 Blackout barrel? Thanks.

Tapered(virtus/new) non tapered(legacy/old). They look the similar from the front, the back portion of the lugs are the important piece. The tapered barrel extension is pretty obvious. Legacy extension has squared relief cuts for the lug. You have to match the bolt and extension. Any of the barrels will fit in any of the uppers and work, with the right bolt. Rattler uses a shorter gas system and op rod than the virtus/ legacy.
