| I'm interested in the SS9 rail to go with an Adams Arms upper that I'm buying for a piston build. It's not on Adams list of handguards that will work, but it's not on the list of ones that won't. So I'm curious how much modification the SS handguard will require to work with the Adams Arms system, if any since MI's website says they will work with most piston systems. |
