Just bought another AR

[skeet]

Went to Cabelas the other day and they had Bushmaster ARs on sale..flattops with a Red Dot sight.Since we live in the out of town area here in Wyoming..Waaayyy out of town in fact...I am trying to teach momma about rifle shooting. She is doing well with the handguns and even enjoys some limited shooting with my Wilson Combat. We have a LOT of coyotes and not just a few wolves. I want her to be able to shoot critters that may be after her chikins cat and the dogs..The yotes will also kill calves and even a cow that is down. We have had one cow that we think was killed by wolves..but no way to really prove it. Anyway..Bought one of the Bushy's. I could also put a scope on the thing but feel momma would be better off with the red dot. What do you all feel about that decision? I have an old made in Japan Trashco 1 3/4 x 5 with European type crosshairs I could also use..or even a reflex sight. Just trying to get something she can use in a hurry and at probably shorter ranges. Like some input on this. If ya think I'm wrong..please say so. This Rifle also has the collapsible stock so it can fit her a bit better than a fixed stock. She tried my M-1 Carbine and didn't do too well with it..so..sold the sucker and gonna try this.. One of the sight choices has to be better than the M-1 peep. Any other ideas y'all might have?? If so please weigh in. I'd a let her use my Bushy Varminter but it is a bit too heavy and it is set up with a 4x12 Trophy Bushnell. That sucker is very accurate. It has a 1 in 9 twist and still shoots my 40 gr V-max loads very well. and I sell the hides in the winter.
