I have been thinking about my brother a lot this week. (he passed away)
We use to love going camping and doing some shooting. He only had 2 guns and one of them was an AR-7.
We must have run about 10,000 rounds through this guy. The sights and trigger are really bad but the way it breaks down and stows in the stock makes it a great camp gun or a survival cache rifle.
It's even waterproof when stowed.
I bought one myself years later. The trigger and sights are improved.
