 * 1) A detachable magazine system used to be considered too costly, too unreliable, and nearly completely useless for most serious long-range shooters.
 * 2) In 1999 Accuracy International introduced the Accuracy International Chassis System (AICS) for the Remington 700 series of rifles.
 * 3) As a testament to the reliability of these new systems, elements of the US military are using the AI chassis system on its Mk13 Mod 5 sniper rifle and the US Marine Corps has been upgrading its M40 series of rifles with Badger Ordnance M5 DBM systems.
 * 4) An advantage to the detachable magazine shooter is the ability to carry different types of ammunition to better handle different targets.
 * 5) Badger Ordnance, CDI Precision, and Surgeon Rifles are just a couple of notable manufacturers of AICS magazine compatible trigger guards.
 * 6) The U.S. Marine Corps have been upgrading their M40 series of rifles with Badger Ordnance M5 DBM systems.
 * 7) Both the Mk13 Mod 5 sniper rifle and M40 rifle are currently in use in the world’s hot zones and both use the tried and true AICS magazines.
 * 8) An argument against using detachable box magazines is that they make the shooter shoot faster, reducing their accuracy.
 * 9) In today's military sniper operations, a detachable magazine system is being viewed as a distinct advantage more so than a disadvantage.
 * 10) Police sharpshooters have less of a need for a detachable box magazine because they will not usually encounter multiple hostile targets, or have a need for faster reload times.
 * 11) A bolt-action rifle is composed of a barrel, rifle scope, rings/base, stock, action, and bottom metal.
 * 12) The riflescope consists of the objective, the main tube, the elevation knob, the windage knob, the parallax knob, the magnification ring, and the ocular.
 * 13) The rings and base includes the ring caps and screws, the ring height, ring base, “recoil” lug, and the rail grabber and nut.
 * 14) The barrel consists of the free bore, the chamber, the throat, the rifling tube, the muzzle, and the crown.
 * 15) Current operations have shown that many teams are operating in larger numbers for better security and remain in positions longer, even after taking a shot.
