We look at the two popular .22lr versions of the AR-15
The Smith & Wesson M&P 15-22 is a well made almost all polymer AR15 style rifle that can use most AR accessories like grips, lights, stocks, slings, etc
The Colt .22lr M4 Tactical Rifle is made from alloy so it weighs a bit more and feels more like a standard AR15
The Colt version looks more like a typical AR15
We look at two .308 caliber AR-15 / AR-10 style rifles from Rock River
The 20 inch and 16 inch versions of the LAR-8.
These are well made heavy hitting semi-auto rifles
