In  2006, I recognized a deficiency in publications and quality articles for 
  professional shooters (people whose job it is to use a precision long
rifle) .   So  I decided to start publishing a digital magazine that
featured  articles by snipers for their fellow snipers. 

This  was no small task— however, the concept was quickly
seized and taken up by  several former Army, Marine and law enforcement
snipers.

Also  the industries  that support the sniper community were
generous with their time and  efforts to ensure that new products, weapons, 
and optics were properly and  accurately covered in the magazine.

In  November 2010, we published our 24th issue— We have interviewed industry 
leaders, offered sustainment articles, reviewed weapon systems, optics, and 
  tactical gear.  With 4800 current readers, we are growing daily into a  
professional journal that still remains true to its core. . . Assisting  
professional shooters maintain their skill sets, and add new ones, all while 
  keeping the advertisement level low and the bull crap even lower. Check 
  us out—  we publish 6 times a year

'The time the unit allows the sniper to devote to sustainment training determines the snipers overall proficiency.  Experience has shown that to maintain a degree of weapon familiarity needed to engage targets at unknown distances, the sniper should devote at least 8 hours a week in sniper marksmanship training.  This amount of time spent in quality marksmanship training will sustain the sniper's proficiency in the art of precision long-range rifle fire. '

In Brief: Accuracy International (AI) Ltd. was formed in 1978 by two times  Olympic Gold Medallist, the late Malcolm Cooper MBE, Sarah Cooper, Martin Kay  and the designers of the weapons, Dave Walls and Dave Caig. All were
international or national target shooters.
The original designs incorporated performance enhancing features learned in
Olympic and international target shooting onto a rifle platform exhibiting full
military ruggedness. This unique package ensured that the weapons were optimised  for the function they must perform, something that cannot be achieved with a  ruggedised sporting weapon.
 The current designs faithfully follow this original concept but also benefit
from thirty years of continuous improvement, driven solely by the needs of
users, highly trained military and police units in over 60 countries
worldwide.
