Just bought the laser boresight last night at cabalas. It is the cabalas brand for 54.99. Brought it home read the directions and bore sighted my 35 that just had a new muzzle brake put on. Well I was kind of sceptical because even though I marked my scope before removing it it was off pretty good. After I was done with the 35 I got my 204 out which I know is in ,and low and behold the dot is right on where it should be. For the money I think this thing will be worth every dime compared to the price of ammo.
