I dont like it like i hoped to! - SightMark Triple Duty Universal Laser Bore Sight

I have the green triple duty and magnet is just strong enough to hold onto the barrel. It fits good on my handgun barrels but not so on the rifles. I would assume the muzzle device would need to be removed from barrel to fit securely but that would be too much work! I got this because I got my money's worth from a lase trainer which is way more accurate and useful for sighting in as well as target training. I honestly would not recommend this for any other than a handgun!
