I now have 2 20" Bushmasters, 1 flattop and one not. I also have a Cobray 37mm flare launcher. I am thinking put the launcher under the flattop with an aimpoint, MIAD grip, a few internal tweaks and call it good. My thoughts for the other one are to make it a 'designated marksman' rifle, maybe a 3x9, regular handguards, bi-pod, MIAD, and the same internal tweaks as the first. Add a nice National Match type leather sling and be done. Any other ideas? Suggestions? I also have a S&W AR, all decked out, EOTech, MIAD, Magpul stock, quad rail hand guard, etc. Thanks guys.
