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
