Have been looking for a rifle to add to my collection, and have seen .223's range from $1,800 automatic to a $300 bolt style. I definitely want a semi-automatic, or possibly with a 3 round burst. Bushmaster seems to be the most advertised in my area, and have looked at a couple others, like the Mini-14 and a ranch model.
Well, when I was looking into a semi-auto .223, I noticed the same thing. I opted for the Mini-14, although sometimes I kinda wish I'd got the Mini-14 Ranch instead, or maybe one of each so I could outfit them with better sights and/or scope easier. BTW, I bought mine back in Y2K, so that was before they made this last round of improvements on sights and a couple of other things. (Don't be surprised if this thread goes 50-50 between advise and bashing/defending the Mini-14 as it happens quite often.) Good dependable Mini-14 mags can be had too in 10, 20, and 30 round capacities, but most brands is a crap shoot with emphasis on crap. I'm thinking Butler Creek is making plastic Mini-14 mags now, but I haven't bought one and tried it yet.
I would recommend you also do look into a good bolt action rifle.
When you get into the 3rd burst or full auto, you're getting into another class of weapons and not only does the price of the weapon increase drastically, so does the ammo bill. This is just me, but I don't see myself rolling da-switch over that often to justify spending the extra money over what a regular semi-auto costs. That's a question you have to ask yourself.
What are some suggestions for a quality semi-auto rifle other than Bushmaster, Arma-Lite, etc....looking for a less expensive model, but a quality and raliable and accurate model, preferrably with a 10+ magazine capacity.
USGI M1 Garand, but that's .30-06 with 8rd en bloc clip. I like mine.
Springfield Armory Inc. M1A, caliber .308Winchester. Takes 20rd M-14 mags.
Ruger Mini-14 in either version. Comes with factory 5rd mag, but takes 10rd, 20rd, and 30rd aftermarket mags some of which, as I said earlier, are better than others.
Rifle also does not necessarliy have to be a .223, just magazine fed with a capacity of 10 or better.
