Hi guys, I am a new member from Franklin county. Still hasn't applied for pistol permit yet so I wanted to buy something just as cool. An AR-15. I don't want neutered "non character" rifle and would rather get a AR-15 with fixed mag. Few questions regarding it. 1) I know there are simple kits that I can install to make Mag fixed. Can I buy AR-15 and install it myself and I am good to go? 2) Or, should I have the FFL do it for me. 3) Lastly, I have been thinking of getting Colt LE6920? Any thoughts about it? It has mixed review but I thought it may be the best one around $1000 budget? Any thoughts? Thank you!
