Boresighting my new ar15

[Thaglyde]

I purchased some milspec flip up sights and I need to sight it in and also sight in my new 1.5x4 scope that I bought from the gun show over the weekend.
I want to get a laser bore sighter but Im not sure which one to get. Any suggestions?

Just start at 25 yards with a big piece of paper. No laser necessary. You'll be on paper at that range and can start adjusting and moving out to 50, 100+ yards incrementally.
