Went to the bay this weekend. Haven't shot for 2 years, except for the CCW quals (VP9 and Shield). I know a firearm that's property stored can sit for a while. Trust, but verify. So my AR, I used grease because the oil kept drying out and I got tired of checking ever other month or so. IDK the brand, got some free grease when Mrs. CMO attended the girls only classes in CO a few years ago. They gave out various samples of stuff.
I also wanted to shoot my ammo that isn't stored in a air tight ammo can. I usually shoot this ammo once a year, but with covid and range closed, I haven't. So about 4 years the ammo was out in the open air. It all functioned correctly, from 223, 9mm and 45acp.
Got to shoot the 1911 and I missed it as my range time with her was limited since I purchased her.
