Cost Effective Solution

by Alan - ATL, from United States, GA Written on December 19, 2014
This seems to work very well. Had to replace the batteries but this was a re-furbished unit so I'm not surprised. Worked well on my Sig 556 but I have removed the flash hider. It will be interesting to see how it works on my SKS with the flash hider in place....
Pros:
  • cost
  • small size
Cons:
  • Battery retension is flimsy
Would recommend: Yes

Best and Easiest Bore Sight you can ever use.

by Big T, from United States, MO Written on December 8, 2014
I used this bore sight on my AR15 after missing a deer at 50 yards twice. After using this laser at 10 yards, I then went back to hunt and shot a dear at 100+ yards running. It was a head shot. Thanks Optics Planet for a fine piece of equipment.

I recommend this item for anyone. In fact I bought one for my son....
Pros:
  • reasonable price.
Cons:
  • nothing
Best Used for:
  • any rifle or pistol
Would recommend: Yes

Fast Zero in

by Fred, from United States, CT Written on November 23, 2014
A must for sighting pistols and rifles. I've used bullet round laser sighting and multi-caliber teardrop laser sighting. This beats them all. I checked sighting on three pistols and a new rifle scope zero in no time. Nice on/off switch. The self centering magnet attaching to the muzzle is genius. Just attach and sight! I chose the red laser, and it is bright. Note: I have only used it indoors so far, and plan an outdoors sighting soon. I expect this very bright laser to do just fine outdoors as well....
Pros:
  • Easy to use. Attach to muzzle and go!
Cons:
  • None
Would recommend: Yes

Good Laser bore sight, value for $.

by Sandman, from Australia, WESTERN AUSTRALIA Written on September 9, 2014
Works great. I have used mine on every thing from a S&W 357 Revolver to a .22 Bruno rifle.
Easy to use and saves time and ammo in setting up your optics.
Found that the magnet didn't hold on all that well in the bigger bore rifles due to either a weak magnet or not enough metal to attract too with the 30cals. But still works providing you keep the gun supported and don't make sharp moves or it will fall out of the barrel.
Go for it !!...
Pros:
  • Small and light weight
  • Gets the job done without the fuss.
Cons:
  • A little too light in construction
  • Magnet not very strong but is ok for the job at hand.
Best Used for:
  • smaller calibers like .22
Would recommend: Yes

Accurate time saver

by Legacy Reviewer, from United States, TX Written on January 13, 2014
Received the Sightmark Triple Duty Universal Laser Bore Sight and tried it out. Super easy to use. First put it on a .22 rifle I just set the scope a few weeks ago. Red dot showed up exactly on the crosshairs as I hoped. This tells me it must be pretty true. Only concern I have is the ON Off button design is almost guaranteed to get turned on in the case and run the expensive little batteries down. I put a piece of tape over the On side so it can't accidently get pushed easily in the case. Its a simple fix the manufacturer should address to make this convenient little product near perfect for my purposes of getting on paper quickly and cheaply.
Pros: Super easy to install and accurate
Cons: On Off button design is a booby trap battery killer...

Good for rough sighting in, but not exact

by Legacy Reviewer, from United States, UT Written on September 14, 2013
I got this to roughly sight in my trap gun and it worked decently. It is not precise but it will get you on paper at least. I bought a demo model at a discount and it was worth it, but I definitely wouldn't spend $44+ on one.
Pros: Easy to set up and use
Cons: Not very precise, pricey for what you get...

Easy to use

by Legacy Reviewer, from United States, AZ Written on September 5, 2013
It is pretty hard to make sure it is centered in the bore. It won't hold the exact zero if you take it off, and put it back on. You cannot see the laser in bright daylight, farther away than 30 yards. It will get you fairly close, and you can do the rest. Will not work at all on an aluminum flash hider, or compensator.
Pros: Very easy to set up and use. Works with almost any gun.
Cons: Not bright enough to use outdoors, except at night....
Would recommend: Yes
