The Forster Sight Fixture with 6-48 bushing is a precision gunsmithing tool built to handle the exacting work of drilling and tapping receiver holes for scope mounts, receiver sights, and other accessories. Whether you're a professional gunsmith or serious hobbyist, this fixture brings repeatable accuracy and confidence to one of the most critical jobs in gun assembly—one mistake can spoil a valuable firearm, making a quality jig an investment that pays for itself the first time you use it.
The fixture works with virtually all bolt-action, lever-action, and pump-action rifles, provided the barrel can rest in the V-blocks. Tubular-magazine rifles are handled the same way after removing the magazine tube. The cast-aluminum body features hardened steel V-blocks that are adjustable for height and precisely ground, so your barrel sits in perfect alignment every time. The sliding over-arm is keyed and runs in a T-slot, keeping it always true to the barrel's centerline. This means your drill and tap guides are always positioned exactly where they need to be.
The 6-48 bushing included is one of the critical wear components in a mounting jig—it guides your drill bit and tap with zero runout, eliminating the cocking and chatter that causes tap breakage and oversized, sloppy holes. The sliding over-arm has three holes spaced at standard intervals (.500" and .860" between centers), so you can swap bushings or adjust the arm's position to match any common scope-base spacing or custom layout you need. Every detail here is built for accuracy: the V-blocks are ground, the bushings are hardened and ground, and the overall design keeps everything in rigid alignment so your holes come out true, shot after shot.
If you've been mounting scopes or sights by hand—or worse, eyeballing it—you'll understand why gunsmiths who own this fixture call it indispensable. It removes the variables and lets you focus on doing the job right, every time.
| Brand | Forster Products |
| Model | Sight Fixture with 6-48 Bushing |
| Main Body Material | Cast aluminum |
| V-Block Material | Hardened steel, ground |
| Over-Arm Slots | Three holes; .500" and .860" standard spacing |
| Included Bushing | 6-48 |
| Bushing Construction | Hardened and ground |
| Compatible Actions | Bolt-action, lever-action, pump-action rifles; single-barrel shotguns |
The Forster Sight Fixture handles virtually all bolt-action, lever-action, and pump-action rifles—including Savage 99 and Remington 760 models—as well as single-barrel shotguns, provided the barrel can be laid into the V-blocks. Tubular-magazine rifles work the same way after you remove the magazine tube.
The 6-48 bushing is a hardened, ground guide that fits into the sliding over-arm and directs your drill bit or tap through the receiver with zero runout. This prevents the bit from wandering and stops the tap from cocking—the leading cause of tap breakage. The fixture is designed to accept interchangeable bushings of different sizes, so you can use the correct bushing for whatever drill bit or tap size your job requires.
The sliding over-arm has three holes positioned at standard intervals (.500" and .860" between centers). You can move the arm to use these preset spacings, or slide it to any custom position you need, all while the keyed T-slot design keeps it perfectly aligned with the barrel's centerline.
Oversized, poorly drilled, or tapped holes weaken the receiver, cause loose mounts, and ruin a good gun. The hardened, ground V-blocks and bushings in this fixture eliminate runout and chatter, so every hole comes out true and the right size. It's the difference between a professional job and one you'll regret.
