I completely agree with this. You will do yourself a greater favor by spending a little money on a tripod and a PIG saddle. I run this setup, and the ability to leave the rifle locked on your threat area exponentially reduces fatigue compared to holding it up with sticks. It also makes a much more stable shooting platform.
My AO is a mix of everything from trailer parks to miles of open terrain, and we are expected to be able to solve problems in any of these circumstances. Even on rural ops I still carry the tripod because it allows me to set up in a sitting or kneeling position when utilizing large piles of brush for concealment. After spending a little time behind the tripod, I consider it a piece of equipment that is a must-have for police sniper operations.
