Review on Accurately Sight In Your Shotgun With The Sightmark Red Laser Boresight by Aaron Webb

I already own two other caliber Sightmark laser bore sights, so it was not a hard decision to purchase this one. Although some review made various complaints.E.g. "It is not accurate.I rotate it and it does not stay on point" - not true with any of my Sightmarks. "The battery runs out." Hello! Its not a laser sight.use and stow. "It jams when I load it".well, first, WHY would anyone load it like a load? Place it in the bore.it's a piece of electronics, not ammo! "I can't use it in day light". Ug, I have a Mossberg 500 JIC, made for CQC or home defense. With that, I only need 25 yards. I had NO problem sighting it in, upon my drive way, at a white garage door. Anyways, I'll put to rest all three of those complaints (at least in my controlled tests).I kept it on way more that I should, for the purpose of OVERUSING it (I needed to sight in my holographic red dot and laser).there was NO noticable drop in battery life or laser output. I then put the unit in the chamber, secured the gun and rotated the sight 360 degrees (twice).no change in placement of dot!. I then chamber the unit 12 times in a row like a shell (good hard slams), no jams or failure.even rechecked the alignment again. Dead on. Last I stood the full 150 feet of my drive way in daylight, and saw the dot! In close, everyone do/buy what you want, but Sightmark is the ONLY laser bore light I will ever own. P.S., for those that want an on/off switch and don't like twisting the cap or removing the batteries for storage. "oh please.I won't even comment on that". This is NOT a toy. I am not knocking anyones past experience. This is only mine.for what it is worth.
