Bore shighting tool

[Karate]

I have acquired several long guns in the last 6-8 months...A Browning A Bolt(mentioned in another thread)...a Marlin 336...a Mini 14 Ranch Rifle and an AR-15 Carbine...I was thinking of purchasing a bore sighting tool...I have seen some that look almost like a scope themselves that attach to the end of the barrel and others that a small laser that attached to the barrel(this is what I found when I went to Wally World)...If I buy one I want to get a fairly good one that will last a long time...but I do not want to spend a fortune on it...so what is the best type and brand for the money...I like the looks of the one that look like a small scope...Thanks Guys and Gals

PS I would like to keep the cost between $100.00 to $200.00 and closer to the $100.00 if possible.

I post this in the rifle section and after a few hours decided to post here
Thanks

Those are lazer sights, not bore sighting tools. There is a lazer bore sighting tool here. $49.00. Don't know how well it works though.

Bushnell makes a bore sighter that does work. Just remember that a bore sighter only gets you on paper. They handy for mounting scopes too.
