I was going with a semi-XM177E2 look, but I like the A2 sights better. Even managed to find a retro-style sliding stock, although it's made of plastic and has 4 positions, not 2 like the original. Until I get an SBR stamp, I can't use the real XM modulator (or a correct copy), so there's a 5.5" semi-XM permanently-mounted flash hider on the 11.5" barrel. It's got M4 handguards, side swivels for a 3-point Giles sling (should be here any day). Don't know if I'm gonna throw a quad rail on it yet, but I love it so far! What do you guys think (sorry for the crappy pic, I hope to have better ones soon!)?
