NcStar laser bore sight kit for $75.00 on ebay-no tax no s/h. Ease of use,saves time and money (ie ammo). Comes in a soft case with room to expand-I added .12 gauge to mine. Just drop it in (chamber bore sight). I have done 2 .308's/2 .223's a .458 and several .12 gauges. Comes with 12 batteries and directions.--Great buy-check it out and good luck. Saved my self $22.00 plus tax from the local gun stores.--hope this helps. Using these is like a Ronco Product just: "Set it " and "Forget it" -
