It's just a standard, issue trigger, with the exception that it's been NiB coated. It's more smooth than a standard trigger, and the fact that it's Nib coated gives it slightly less trigger pull than the issued, stock triggers that you see in the regular Mil rifles. Just a smoother Mil trigger. I've been using one since mid-2010, and it keeps getting moved from rifle to rifle, as I buy more "upgraded" triggers. It's final home, not to be moved again, is in the .45 ACP AR. It's staying there.
