Good Stuff Innovation Zombie Green Cartridge Laser Boresighters .223 .308 .30-06 7mm 8mm

I was able to sight in 3 different optics on my AR in my living room/down the hall way without firing a single shot (though i did make some adjustments for greater range). This product is ingenious and affordable. The battery life does suck pretty bad, kind of a one time use situation, but I was able to take my time and get everything sighted. Plus the batteries are changeable. This product deserves 5 stars. Everyone should own one.

Haven't gotten down to the range yet to check its "zero" accuracy (a bit cold up here in the North East right now) but ease of assembly and installation was good. Did not have any issues with the unit jamming in the barrel bore, just don't let the charging handle fly like you would with a live round, just ease it down into battery. Note that there is no way to shut this thing off w/o removing the batteries so make your dial-in adjustments quickly and then power it down, the batteries are micro-miniature in size and no idea on total batt life. The laser was pretty bright and worked well sighting in down my apt hallway to the back of the bedroom wall. So far, so good.

$10 junk, points in a different area every time its placed in chamber, laser was not installed parallel in case. it's not worth the effort to return so it's a toy to mess with the dog now. I can eyeball boresight better so back to old school.

Worked great a couple of times then it died, tried changing batteries. No go. Now it sits in a drawer.

Works great. Sighted in 2 rifle scopes on different rifles, within 6 inches once on paper. Only thing that would make it better is some sort of on/off switch, but I imagine that would be at the sacrifice of battery life. All in all, a good product that does what it is intended to do.

Good product just make sure when you’re using it you have a cleaning rod it does get stuck in an AR

great i use frequently, I work at an indoor shooting range 25yds and this puts scopes at zero with approx. 3 to 5 real rnds.

Works great. Sighted in my rifle quickly. was easy to assemble as directions stated.
