Hello everyone, my gun dealer told me he would be getting my 15-22 last Friday... turns out they are on backorder and it's been three weeks now. He said he could get the California Regulated model with ease, but the 25 round model is on backorder and he really don't know when they'll be coming back in stock. I kept my name on the list, but, if he can get the Cali model, what are all the differences between the rifles? Any help is greatly appreciated.
