.30-06, .270, .25-06 Boresight

Great product

The laser reflected off the barrel and made it very difficult to sight in my rifle

all laser boresighters I've ever purchased are sightmark "in the chamber" sighters. only enhancement request is some kind of on/of switch/valve so I don't have to remove (then lose) the batteries. using sightmark at a 25 yd indoor range, then Applied Ballistics or Hornady 4dof and accounting for 25 yd vs 100 yd, my friends have been stunned me first shot at 100 yds is almost 2" or less off true zero. these products are awesome! (I have 30-o6, 223, 338 lm, 6. 5 cm, 308, 30-30. next is 7. 62x54r and 22lr if sightmark makes them (and when I'm ready)
