Barely got my bore sighted before failure - Sniper 7.62x39mm Laser Bore Sights

Not worth the money. Could have spent the money on ammo to put into the dirt trying to get it sighted instead of wasting it on this and the frustration that came with it. After about a minute the laser started to flicker and will change brightness levels with any bump. Then once you remove the rear cap it will come back on and then after a second will dim and flicker and then come back on. I tried new batteries and that didn't help. Would not recommend
