Helpful Positive Review Laser is great, not quite the best for AR in 450 Bushmaster by estsco, Verified Owner, May 17, 2018
When used with an AR-15 in .450 Bushmaster caliber, the bolt does not close all the way, so the laser does not activate. The laser itself is just a bit longer than a standard .450 cartridge, so the bolt does not close all the way. Was able to act...

Most Recent Reviews 9mm Luger bore sight by jkrucus, May 7, 2017
You need to let the action close into battery to seat the laser and turn it on. On my older S&W 59 it would drop into the chamber, but on my newer Sig 229 and 938 and Kimber Solo it did not drop into the barrel until the action closed. No problem to...
