Within 18 months after Bill Clinton took office I became a Life Member of the NRA.
At that time it was not necessary to come up with the cash all at one time.
The NRA had a payment plan for those wanting to become Life Members.
I don't know if payment plans still exist, but a trip to their web site should provide the answer.
Easy Pay Life (EPL) - Pay $25 today and the NRA will mail you a quarterly invoice until the total dues are paid. Your membership status will be upgraded to Life Member when the balance is paid in full.
That's a good way to get started.
Thanks for the info!
