Most notable is the $2,500 worth of firearms insurance but you also get travel and accident benefits. The value of these free services is $7,500 but that jumps up to $12,500 for Lifetime NRA members. They call this package the "Trio of Security" (firearms insurance, travel benefits, accident benefits) and you can easily and quickly sign up at http://www.nraendorsedinsurance.com/no-cost-trio-of-security.
It literally took me 3 minutes to fill out the online form and activate my benefits. With all the guns I own, I can use all the insurance I can get!
If you're not an NRA member, you can get a $10 discount if you sign up through my referral link: http://bit.ly/1rZyctJ
