Could build a Juggernaut for the price of the SCAR and be twice as cool
But in all seriousness, I have heard some mixed reviews on the juggernaut chassis' for the M1A. But then again, I have heard bad things about the SCAR, ACR, you name it. There will always be reviews on people not liking a weapon, but not all weapons are suited for everyone. I think it is really dependent on what you need it for and how you like the feel of a gun. Shoot some ARs and a SCAR. You may end up liking ARs more. I can not really give any strong advise on why to buy a SCAR, havent had the pleasure of shooting one yet.
