I am looking to purchase a new rifle and i cant stop looking at the Sig 556. I have heard mixed reviews that range from QC to cheap stocks and sights. I like the handguards on the SWAT model I know they are barrel heavy but the weight isnt an issue. I just dont want to buy a Sig and have to worry about quality issues it just doesnt seem right to be concerned about Sig's quality but i am because of what i have read. I owned a Bushmaster for a while and i liked it but i'm really wanting to try something different. Has Sig worked out these issues since the rifle has been out for a while now or is it still ongoing? Please feel free to give your opinions i'm going to make a purchase soon i just need some honest feedback. Thank you
