Same here, two small dogs and a creek runs within, 50 feet of my deck. Other than living in a flood zone we love seeing wildlife that follow the creek to a major river 2 miles away. I had a bachelor group of 8 Tom turkeys inside the fence yesterday and toms and hens at my feeder about 100 yards away all day today. They bring the coyotes. I think you light and laser are the smartest things you can put on one. I have lights but not lasers yet. I have a 1911-22 with light and laser and suppressor and it is great for skunks at night and we get a lot. I have the 10.5 inch and the 16 inch. Like you the pistol is more for fun.I'm with the "fun gun" camp when it comes to an AR pistol.
I built my 300BO AR pistol with a 10.5" barrel simply because I got a good deal on it. I was looking for a 12" but didn't find any at the time. My reasoning was that I was never going to use the AR as a concealed carry or belt holster gun. Just looking at a 300BO cartridge, I could see that there just is not a lot of powder space for the bullet size. It was never going to be any serious hunting weapon for me and is not my idea of a good option for defense against bears or cranky "mooses".
So it was mostly a "just because and fun" gun for me. As for home defense, it's not my notion of an ideal house gun. I do use it -sometimes- for night guard yard duty. We get coyotes all around us and I have 2 little dogs that would make a meal for them. I have a light and laser on it so it might be faster to get on target in the dark and ranges are short anyway.
It is accurate and fun to shoot. Cases aren't hard to make (good thing since I haven't seen factory rounds in a long time). But realistically, I have guns that are far more practical. So as I said, it was built as a fun gun.
That said, I did buy a 16" barrel on sale a few months ago. It's intended to try to wring out a little more performance from the 300BO. And it's just sitting there begging to be built into an upper to try in 3-gun. Again, just for the fun of it.
