MOSANDON Red Laser Bore sight

works great !

Sighted my gun right on target. I only had to use it 3 times, before I was right on the money. I shot a deer right after using this bad boy. Totally worth it!

Jay Fray delivering the solid truth about this MOSANDON .30-06/25-06/270 bore sight that provides quality sighting capability with minor performance limitations! Purchased this MOSANDON bore sight for .30-06/25-06/270 caliber rifles expecting reliable bore alignment for initial scope zeroing before range sessions. The sight quality and accuracy are genuinely good for saving ammunition during rifle setup. Construction quality feels solid with durable brass or aluminum materials that fit rifle chambers properly without excessive play. The bore sight inserts securely and maintains alignment during sighting process. Laser visibility works well under proper lighting conditions with bright projection that’s easy to see at reasonable distances for initial scope adjustment. The laser provides adequate reference point for rough zeroing. Battery life appears decent with the unit operating through multiple sighting sessions before requiring battery replacement. The power consumption doesn’t drain batteries excessively during normal use. Where this bore sight loses a star includes laser accuracy that gets rifles close to zero but requires range confirmation for final adjustments, or caliber compatibility that may not fit all barrel variations perfectly despite advertised caliber coverage. Activation mechanism works reliably though may require careful positioning to maintain laser operation. The on/off function operates consistently without frustrating intermittent performance. For hunting rifles or firearms requiring seasonal zeroing after scope mounting or adjustments, this bore sight saves significant ammunition costs by establishing baseline alignment before live fire confirmation. Value proposition is reasonable for the time and ammunition savings provided during scope setup, making this worthwhile for shooters managing multiple rifles requiring regular maintenance. Jay Fray verdict: Quality bore sight delivering reliable laser alignment with solid construction for efficient scope zeroing. Good tool for shooters wanting to minimize range time and ammunition consumption during rifle setup!​​​​​​​​​​​​​​​​

A quick, easy way to get a new scope shooting on paper without wasting a bunch of ammo. The beam is good to 100 yards at dusk.

Works great, saves a lot of rounds sighting in your scope and pays for itself.

Fits in the barrel but doesn't allow the bolt to close for proper seating. Tried adjusting with it as closed as possible, still didn't get my rounds on paper. Do not recommend.

Won't allow bolt to close on Remington 700 30.06 unfortunately. Hopefully it get's me close enough for sighting in a new scope.

Works as advertised great for readjusting scopes knocked off sight just remember the red dot will not be in the center of the cross hairs once you get it set. So set your scope put up a target a few feet away put cross hair in center and mark where the dot is then simply repeat if your scope gets out of adjustment

This bore sighter will pay for itself. I only use 2 or 3 shots to sight in. The rest of the ammunition can be used for practice and hunting.
