will this work with a .300 blackout upper?
Ken E on Jun 7, 2019
BEST ANSWER: Don’t think so, Ken. The bullet and brass neck won’t seat properly. If you succeed in forcing it without breaking it, the laser won’t reliably shine down the bore bore axis. Spend the time and money to get a 7.62 X 45 Blackout tool designed for your chamber.
can you turn it on and leave it on. or is it a strike only.?
MICHAEL p on Sep 27, 2018
BEST ANSWER: Yes, when you put the batteries in, it stays on. There's no on/off switch. It's probably a good idea to remove the batteries anyway after use, so this works well.

works great, the only down side is that you have to remove the batteries to turn off

Works as it should.
This product works as it should. The only drawback is you really need to remove the battery after each use.

Works fine
Works well indoors, difficult to see at all outside. Recomenf use of the higher voltage battery option.

I only gave this item 4 stars because it has no on/off switch and the only way to turn it off is to remove the batteries, other than that short coming, it works as it should and works well.

Only 1 problem with it. It came with 2-ag5 batteries @ 1.5v =3v each l bought 3-ag3 batteries @ 1.5 v each=4.5v. It recommends either combination but the 4.5 volts gives it a longer range. After that change I would give it a 5 star rating

Great laser for bore sighting. Green laser I'm told is better than red
