Darn, I knew I forgot to do something last night
Cleaned the mags out this morning before work - boy were they filthy.
On the plus side - all 3 20-rounders are Colt. 2 Adventureline 30-rounders. Got about 800 rounds of .223, cleaning kit, and bag with it as well.
It's good to buy from family - I'm in the doghouse for it though, my wife to be had planned on buying it from her dad to give me as a wedding present
