Glad to hear it, Don! Enjoy!
Only two things I'd recommend are, 1, spend good money on scopes and lights. Going cheap will leave a bad taste in your mouth, trust me. You'll just end up buying the same things twice.
And 2, Learn your "hold over" and "hold under" for different ranges. Unfortunately that takes a little time and money, but if you do it instead of just plinking, it'll make you more effective and confident.
BTW the release mechanism is called a "Battery Assist Device", or BAD lever, if it is what i think it is youre describing.
