I want a model that matches the 5.56 chamber or bore size correctly so I can get a reliable starting point for sighting in.

Why I Prefer Laser Bore Sights
In my experience, a laser bore sight helps me save ammunition and range time. Instead of starting from scratch, I can get my optic or iron sights close to zero before I ever fire a shot. That makes the live-fire adjustment process much faster. I also like having a tool that gives me a quick visual reference whenever I mount a new optic.
Key Features I Check Before Buying

Accuracy and Visibility Matter to Me
I want a bore sight that gives me a consistent laser point every time I use it. If the beam is weak or inconsistent, it defeats the purpose.

If the design is confusing or awkward, it slows me down. For me, convenience is a major part of the buying decision.
Durability and Storage
