12GA Bore Sight Red Dot Cartridge with 2 Sets of Batteries

Very useful for initial setup of gun as a cpsa shooting instructor I find it useful.

Tried my luck as per other comments, COULDNT close the gun with it in the top barrel, so pretty useless, I reduced the both ends on a sanding disc and did get it to close. However you need this absolutely spot on and done on a cnc, otherwise if the face isn’t perfect it throws the laser out. If they can adjust this, it would be ok. Save your money and find a different solution.

Product as expected. Good buy and great service.

This item is not fit for purpose. The rim at the base is much thicker than a normal 12G cartridge so that it is impossible to fully close the gun Useless for improving gun mounting which is what I bought it for

Did not fit my shotgun without modification.I had to shave a few mm worth of metal off to close the gun. I should have read the reviews first. Lazer works well, but is not perfectly true. Maybe this is due to filing it down to fit. I wouldn't trust it as a training aid.

The item looks good, it slides into the barrel, BUT YOU CAN’T CLOSE THE GUN thereby making it completely useless in its as sold state To make the item usable you will need to spend a couple of hours carefully reducing the thickness of the screw in cap by just under 1mm using a needle file. Only reduce the thickness of the cap on the outside circumference were it sits in the ejectors of your gun. You need to be careful to ensure that you maintain the same thickness all round or the item will not sit correctly and not give an accurate centre. If you can be bothered and you get it right it a useful piece of kit that will help you to mount your gun correctly BUT UNTIL THE FAULT IS RECTIFIED BY THE MANUFACTURER THIS ITEM SHOULD NOT BE OFFERED FOR SALE OR THE SELLER TSKEN TO TASK UNDER THE SALE OF GOODS ACT.

Do not purchase this product. The head of the cartridge is too thick and stops my over under shotgun from closing. The sighter I purchased is completely useless.

My gun wouldn’t shut with it in,tried it on a few other 12bores and still didn’t work

Mit Abstrichen nutzbar. Bei meinen Flinten war die Genauigkeit absolut in Ordnung. Gut fürs Trockentraining. Richtig nervig ist die Geschichte mit dem Entnehmen der Batterien. Was erstmal banal klingt, entpuppt sich jedes Mal als Bastelei. Und sie sind echt schnell aufgebraucht. Warum es ausgerechnet (mehrere) Knopfzellen sein müssen ergibt hier nicht viel Sinn. Schade, nervig, aber ohne echte Alternative.

Acheter pour régler un point rouge sur un fusil de chasse semi-automatique calibre12. Article de bonne fabrication et précis. Permet un préréglage en économisant des cartouches ,nécessite une vérification par un tir réel sur cible .Je recommande cette article.

Muy bueno para entrenar en casa

It works great

Ottimo e molto semplice da usare
