First off Id like to say Im totally new to guns. Ive shot before, but never owned. I am turning 18 soon, and I would like a rifle. A semi-auto to be exact. I was really wanting a tactical Mini-14 because it looks somewhat similar to the M14(my favorite gun) and it is an overall good gun. But at the same time I kinda want a AR-15. But theres so many AR-15s to choose from. Help me decide! I only want to spend at most $1000 on the gun itself.
