Probably would run a Eotech in it. Kind of like the slick rails but I don’t know. Oh mighty internet commandos tell me what I should blow my money on.
Here is the deal, on a barrel with the FSB, to install the FSP RIS II, you still have to remove the FSB. If you are going to do this, you may as well go ahead and get the DD RIS II, a DD Mk12 low profile gas block, and install them. You can then have the Warcomp pinned and welded. BTW, there are M4 SOPMOD Block IIs in addition to the M4A1 SOPMOD Block IIs. You can build a M4 SOPMOD Block II clone with the barrel you have.
