Fucking nice dude. >>40704644>SCAR
It isn't so simple dude. A SCAR and an AR10 are very different, and excel at different things. For example the SS LMT MWS is reported by some users as being 1/3rd MOA with factory match ammo, while a 17S is lucky to be 1 MOA or so with factory match. Sure there is the 20S, but that is an entirely different conversation as well. It comes down to what your priorities are. If you want a battle rifle DMR, then yeah, go 17s, but realize its limitations. If you want a DMR/SASS, then go with an AR10, as they really are more accurate than a 17s.
I would suggest just getting the new LMT MLKMWS, the one with the Mlok rail, SS barrel, and full ambidextrous controls. It'll be right around $3k, but it'll cover all your bases, while allowing for future barrel swaps if you desire.
If you insist on building, you don't really need to go all the way up to $3k. At the end of the day though when it comes to AR10s you're really better of buying. Take this from someone who did a build.>>40704834>Not a modern profile barrel>Ugly rubberized furniture
Not worth it at all.
