Hi all, So I bought a stripped DPMS lower recently on a whim from a local private seller. I've been doing my homework as to what exactly I want out of it, which is a bit tough as I haven't really handled AR-15s before. Think of this as an urban E&E weapon, relatively short & quick handling, not a range queen or precision weapon. So far, this is what I think I want out of the build: * 16" barrel, carbine length gas system * moderate accuracy w/ iron sights - I'm not taking 500m shots with this (will add a red dot sight down the road) * chrome-lined barrel * 5.56 chambering rather than .223 * gov't profile barrel, not bull/heavy or superlight * collapsible stock * 1/7 or 1/8 twist * M4 'extended' feed ramps ideally * F marked front sight post * flattop upper I've done a little digging and found this kit which seems to meet most or all of my wants: Palmetto State Armory 16" M4 Standard Rifle Kit I figured I'd go with a complete kit for my first build. Anyone have experience with kits like this, or other thoughts in general?
