A tactical rifle is used under stress, usually when all other measures have failed and human lives are in danger. At the critical moment, all components must work flawlessly, every time. This prime consideration flows through all the decisions a stock designer must make when developing a tactical stock."
Now, I have nothing agasint tactical stocks. On the other hand, has anyone ever heard of a stock not "working flawlessly"? All the metal hardware, yeah, I could see. A tactical stock looks cool, is more comfortable, gives you better cheek weld. I guess for a sniper who has his/her face stuck to it, sometimes for hours at a stretch, comfort is important. But failure of a stock? If you consider the tens (hundreds?) of millions of hunks of hardwood countries have sent to war over the past 4 centuries, the number of cases where the lumber didn't "work flawlessly" is extremely low.
