I bought a sig virtus complete bcg awhile back for my 9” virtus blackout and when I installed it I realized there was a difference between a rattler and a regular virtus recoil assembly. I was told it would swap interchangeably between the two but that’s not the case. I need a virtus assemble with the longer op rod assembly and would like to either buy the recoil assembly or swap bolt assembly’s. Not wanting to sell as this is kinda mandatory for my Mcx to operate, lol.
