Let’s Dive into Sightmark Laser Bore Sight, 8mm X 57 JRS, SM39029 – 1 out of 29 models

Zeroing a rifle used to be a tedious, ammo-wasting chore. Then came laser bore sights, promising faster, cheaper accuracy. The Sightmark Laser Bore Sight, 8mm X 57 JRS, SM39029 – 1 out of 29 models specifically caters to the 8mm Mauser, a caliber often found in classic hunting rifles.

I was tired of burning through boxes of expensive 8mm ammo just to get my old Mauser dialed in. The promise of a quick and easy zero using the Sightmark system was too good to pass up. Initial inspection revealed a lightweight, compact device.

It seemed simpler than some of the magnetic, muzzle-insert designs I’d seen. Unlike universal kits that require shims and adjustments, this model is dedicated to the 8mm X 57 JRS caliber. My first impression was cautiously optimistic, hoping it lived up to the hype.

Real-World Testing: Putting Sightmark Laser Bore Sight, 8mm X 57 JRS, SM39029 – 1 out of 29 models to the Test

First Use Experience

I tested the Sightmark Laser Bore Sight at my local outdoor range, which has a dedicated 100-yard rifle section. The day was clear and sunny, ideal for sighting. Chambering the boresight was straightforward, just like loading a standard 8mm cartridge.

The laser dot was clearly visible on the target at 25 yards, even in daylight. I adjusted my scope turrets to align the reticle with the laser dot. No special tools or extra hands were needed for this.

The initial alignment at 25 yards was a breeze. Moving to 100 yards, I anticipated needing only minor adjustments with live rounds. My first shot at 100 yards was surprisingly close to the bullseye, requiring only a couple of clicks to center the group.

Extended Use & Reliability

After several trips to the range, the Sightmark continues to provide a reliable starting point for zeroing. It consistently gets me close to the bullseye, saving time and ammo. The brass casing shows minimal wear.

It still chambers and ejects smoothly. I clean the laser lens with a cotton swab and isopropyl alcohol after each use to maintain brightness. Compared to my previous method of purely using live fire, the Sightmark is a game-changer.

Previously, I would have needed 15-20 rounds to get close to zero. Now, I’m typically dialed in after 3-5 rounds.
