New ICS Project

[Hitman_Actual]

Evening all,

I recently purchased a second hand ICS 47, with the intention of taking it apart to learn more about the parts, and then upgrade and rebuild as I go. (I know its going to be a money pit!)

I would like to replace the current plastic upper & lower with metal versions, so my first question is.... will these work:

Next I would like to replace the current 2 part rail system with a RIS handguard, so something like this?

My concern is if it will work and attach to the new metal upper receiver ok?

Any help appreciated!

Thanks
