So, it has come to my attention that there are simply too many platforms amongst the firearms manufacturers and the market for conversion products is limited. For example if you want to jump between.... picatinny, keymod, m-lok, RMR pattern, ACRO, ARCA, high rise, mid rise, low profile etc. the products just don't exist. Even in my own experience I needed an RMR to mid rise picatinny rail... which didn't exist.... till I made it. Final price will vary depending on project complexity. We will communicate all expected changes in price.
