I have a few quick questions for anyone in the know...
Is there any compatibility between MV and MS uppers and lowers? I know ATRS sells complete uppers for the MV...will these work with the MS lower? I'm sure this is pretty basic stuff and covered elsewhere but I haven't been able to track down a definitive answer.
I was also wondering if anyone had installed either a KAC or PRI handguard on an MS receiver and if any complications arose with compatibility?
Many thanks, SH
