Sightmark 7mmx65 REM Premium Laser Boresight

The Sightmark 7mm x 65 REM Premium Laser Boresight from Sellmark Corporation delivers a fast, non-destructive method for zeroing rifles and shotguns across caliber platforms. Unlike traditional scope mounting that requires live fire to confirm zero, this laser boresight chambers like a standard cartridge and projects a visible laser dot aligned with the bore axis—allowing shooters to dial in elevation and windage adjustments without expending ammunition or traveling downrange.

The 7x65mm REM caliber specification matches rifles chambered in 7mm Remington Magnum, making this boresight ideal for long-range hunting platforms and precision rifle builds where ammunition costs and range time justify tool investment. The compact form factor—5.35 inches in length and 0.26 pounds—fits standard rifle chambers and feeds reliably into magazine-fed systems. Once bore alignment is confirmed and basic scope reticle placement is established with the laser, live-fire validation is confined to verifying ballistic drop compensation and velocity-dependent drift—substantially reducing ammunition waste during the sighting-in process.

This tool addresses a critical workflow gap for long-range shooters, competitive marksmen, and hunters preparing specialized or expensive ammunition loads. Field professionals and serious enthusiasts benefit from the speed advantage when servicing multiple rifles, switching optics, or performing bore verification after transport or storage. The laser boresight approach eliminates guesswork in initial scope mounting, reducing the number of sight-in rounds required and allowing shooters to begin load development or field validation from a known baseline rather than an unknown zero.
