Very tempting.
Lots of online catalogs with “out of stock” right now.
Bird in the hand.
That 16” rifle with a decent red dot scope is a fine home defense unit.
What is the barrel twist? 1 in 9 or 16 is standard. Bushmaster is a good brand and can shoot .223 and 5.56 ammo. I have one and love it. But if you want home defense, get a shotgun or a Moisin-Nagant.
