Your post reminds me that when I shot mine for the first time, I grabbed a box of Federal bulk pack I had on hand. I later realized that I had purchased it in 1992.
Well, I bought one of these and threw on an extra Aimpoint I had for the first range session.
Then, like many of you, I had a Magpul party.
It is sure easy to add a lot of money to these little rifles in a hurry!
