Hello everyone. I am in the market for an AR-15 and I am about to pull my hair out! I have been looking at Bushmasters, and there are SOOOO many different models and I can not sort out the differences between them all. Some look identical to one another, but there can be like a $200 difference in price and some abbreviations I can't decipher. My allowance is about $1200. I am looking for a home defense/target shooting rifle in .223 caliber without the carry handle. I dont much care if its all decked out because I wanna pick out all my accessories later when I have more cash available. I need some help. I wanna go with Bushmaster, but I am open to other brands.
