The Firefield FF39011 in-chamber bore sighter is a straightforward tool for fast, accurate rifle zeroing without firing a shot. Built for 30-06 Springfield rifles, this red laser bore sighter drops into your chamber and projects a beam downrange to help you align your scope or iron sights to your barrel's point of aim. It cuts setup time at the range and saves ammunition during those initial dial-in sessions—especially useful if you're mounting a new scope, switching between rifles, or breaking in a freshly built gun.
An in-chamber bore sighter works differently than a muzzle-mounted option: it uses the chamber itself as a reference point, which means you get a sight picture that's already aligned with your rifle's actual bore. The red laser (632–650 nM wavelength) is visible indoors and at modest distances outdoors, making it practical for pre-range prep in your shop or at a covered range. Just cycle it into the chamber, aim at a target 25 yards out, and adjust your scope turrets or front sight until the crosshair matches the laser dot.
This is a budget-friendly way to get close to zero before you fire live rounds. It's not a replacement for a final live-fire verification—always confirm your zero with actual ammunition—but it eliminates the guesswork and wasted shots that come with a completely cold barrel. If you shoot 30-06, own multiple rifles, or mentor newer shooters, having a dedicated bore sighter in your range bag makes every setup faster and more confident.

Yes, the Firefield FF39011 is designed to fit the 30-06 Springfield chamber. Simply insert it into the chamber as you would a round, and it will align with your barrel.
You can use it indoors or outdoors. The red laser is visible at typical indoor distances and modest outdoor ranges (roughly 25 yards), making it suitable for shop or covered-range zeroing before you move to live fire.
No. The bore sighter goes directly into your chamber with the bolt closed, so you don't need any ammunition. It's purely a laser-based aiming reference tool.
An in-chamber bore sighter gets you very close to zero and saves time and ammo during initial setup. However, you should always verify and fine-tune your zero with actual ammunition from the shooting position you'll hunt or compete from, as final zero can be affected by scope mounting, recoil, and shooting technique.
