Good morning EtR
Mark Stone was using one on his .22 in the Summer 2011 No 64 edition of Sporting Rifle. Normally they give the usual advertising blurb but in this case very little was said except that it was rated four stars, imported through GMK, priced £66 and allowed lamping between a " dull but usable green glow and an intense emerald beam". I'ld like to know usable distance etc.
