BSA Bore Sighter is an excellent investment!
Set name: Bore Sighter Kit with Arbors
This is my second Bore Sighter Kit. My other BSA kit has the shotgun arbors. This one does not. I dropped the sighter scope and needed another one so this is what I ordered. If an arbor fits loosely, as others have done I found a good work around: I cut off a 4" piece of kite string and slid half of it into the bore. The arbor clips as well as the arbor itself snug up really nice with the string and eliminate wobble. Both kits are well worth the money if you shoot a lot and swap scopes like I do. It saves many rounds of ammo if you can be on paper on the first shot. Shoot 3 for the initial sight in and then adjust the scope. You should be all sighted in in less than 10 rounds. 3 at 50 yds to start; 3 more after sight is adjusted. (set for about 1.5" over at 50 yards. Then if your rifle is a 100 yard or longer range gun move the target to 100 yards.) Shoot 3 more. Work on from there. If you have a new rifle shoot it in and clean the bore often during the break in. It does not hurt to make a record of your initial grid setting if you set the Bore Sighter anywhere other than dead center. Then after a session at the range, re-sight with the bore sighter, leaving your scope set but re-recording where the crosshairs are at now compared to where it was, as well as the number of clicks you had to move the reticule to zero the scope at the range.

Good product
Set name: Bore Sighter Kit with Arbors
This a great product. I was able to zero my scope easily. The big plus is I use less ammo and I don't have to buy batteries for my laser boresighter.

BSA Scope Alignment Device BS30
Set name: Bore Sighter Kit with Arbors
The purchase processing was expedient. Upon receiving this item, I set it up on my Ruger 10/22 rifle. First, I noticed that the arbor for the 22 LR caliber, would not stay exactly in the vertical position. I toyed with the arbor and came to a conclusion, it needs to be taped down, so it won't sway from its up right position. After this was accomplished, I could sight in my Ruger rifle and Nikon scope without a problem. The arbor's need a better holding design, so one can fit it into the barrel without any fuss. They do have a holding clip mounted on the top side to prevent this from happening but, it doesn't seem to work well unless, I try bending out on this clip to get a tighter fit. I have not tried any of the other caliber arbor's to see if that issue remains. Other than that issue, I'm pleased with this device.

Best bore sight on the market.
Set name: Bore Sighter Kit with Adjustable Arbor
Best bore sight on the market. I sighted in my 50 cal muzzle loader at 100 yards. When I tell you I can drill a penny every time, I am not kidding. Save your ammo trying to sight in your optic and buy this. Very please and impressed!!!
