Sightmark Red Laser Boresight for .223 and 5.56x45 NATO Rifles

Jason Rife: I bought two, 300 win mag and 308 win, friend said they don’t work well. I didn’t use them, went sighted in to about two inch pattern at 100 yards. Got home slapped them in and holy crap they were right on the money. Crosshairs both rifles….¯\_(ツ)_/¯

Jason: Fits my.264 win mag perfectly. Light seem very bright on the wall in the reloading room. Haven’t shot the gun yet though

PJ: nothing more accurate to calibrate your weapon that a laser bullet chambered inside the barrel. Forget those sticks you stick in the front of the barrel, they stink.

Brett: Not MOA accurate, neither are most 7.62x39 rifles you'd be shooting it out if either. Will get you on paper at 100. Should get you within 10 inches of your aiming point. Beats not even finding the backboard with a new scope. You might only use it a couple times, but share it with a friend on the fange if you see them struggling.

Amazon Customer: Fits in the bore of my Tikka T3 perfectly. No slop, and no problem extracting. Don't know about accuracy as yet as I haven't had the gun out to the range.

Kindle Customer: This is the fourth caliber I have purchased, although I have not actually tested this exact one yet. The concept is very good, the manufacturing tolerances leave a lot to be desired. For the price, they should work better, but I keep buying them (grudgingly) because I finally figured out how to make them SORT of work for me, at least better than other products that I have tried. I originally bought this product for three reasons: 1) To help me bore sight some scopes that I was installing. 2) To use to check the accuracy of some QD mounts when I re-installed some optics that had been previously sighted in. 3) To check my scopes after traveling or having them bumped. Within reason, and with some practice, they work well enough for the first reason, but not well enough for the second two. They are somewhat better than the muzzle mounted lasers, but they are not as good as they could be. I gave up on using them to check the accuracy of a QD mount re-install in the field as they are not consistent enough, even with the trick below. After flying I would for sure take a practice shot to check my scope rather than rely on these things.

The problem is they are not centered well. Not...

DarthRad: I have four of the Sightmark laser boresights - the 12 gauge, 9mm, 7.62x39mm, and .223.

I had used a Bushnell laser boresight before getting this set of chamber loaded laser boresights. The Bushnell is the kind that you stick into the muzzle end of the gun, fitted with an arbor matched to the barrel size. The problem with this device was that the arbors never fit quite right - they were always either too tight or too loose, plus you had to try to seat the body of the boresight in the center of the opening of the barrel (or muzzle brake) in order to properly align the center axis of the boresight with the center axis of the barrel. This rarely if ever happened just right as the slightest tilt in the seating of this boresight in the barrel would take it off the center axis so that rotating the laser would cause the laser light to mark out a small circle that was several MOA in diameter rather than being dead centered. Ugh.

Of course with these chamber loaded laser boresights, there is also the potential for the lasers to be mis-aligned off the center axis. Plus there is the potential for the boresight to not fit the chamber properly. The key is to find a brand that has...
