Congratulations, I'm sure you will enjoy it.
Now comes the fun part of shooting it, reading all the cool changes you can make to one, seeing examples of those changes and spending tons of money to make it exactly like you want it.
This little rifle has been around a long time, tons of people have enjoyed this gun since it came out. There are literally too many companies to count that make aftermarket parts for these rifles, so the sky is the limit on what you can build one into.
My wife and I have several, from stock to full on custom built, between us we probably shoot 2,500 to 3000 rounds a month and it is always a blast, regardless of which rifle we shoot on a given day.
Again, enjoy it and be safe.
