20 Gauge Red Laser Bore Sighter
TW00058
The 20 Gauge Red Laser Bore Sighter fits directly into the chamber like a live shell and emits a clear red laser dot—helping you centre your sights or optic before firing. Lightweight and crafted from anodised aluminium, it fits snugly and securely, making zeroing faster and more efficient. It’s a low-cost accessory that reduces ammunition waste and speeds up sight alignment, particularly useful for shotguns with iron sights or red-dot optics.
