I have two of the MI SS Gen2 Free Float Handguards and they are tremendous. Their 1.5″ outside diameter is narrower than just about any other handguard on the market. However, as is typical with rails like this, there can be some issues with heat. That is why I am thrilled to see that MI is bringing a bolt on panel kit to market. The kit will come with 3 panels (2 plain and 1 with a built in handstop). They will be available soon in FDE, Black, and OD Green.
