The 1985 competition to pick a new sniper rifle for the British military came down to a closely fought contest between the Accuracy International PM and the Parker Hale M85. The M85 was a fantastically accurate rifle, every bit the equal of the AI submission and to this day there are still people who were involved in the trials who insist that the M85 should have been selected. Ultimately, the decision came down to the logistical issues surrounding the rifle, where AI's chassis system was superior to Parker-Hale's traditional construction. Despite being defeated, Parker Hale sold some 800 M85 rifles - nearly as many as the military contract would have procured (and in fact, a few M85s were purchased by several military units).
