tactical solutions Buck Mark Picatinny Scope Rail Mount for Pac-Lite — Integral Rear Sight & Drill‑Tap Accessory

The Tactical Solutions Buck Mark Picatinny Scope Rail Mount is a precision-machined Picatinny rail and scope base system designed to attach directly to Pac-Lite barrels for secure optics mounting.

Designed and manufactured in the United States, this suite of scope bases and accessory rails gives Buck Mark shooters a robust, repeatable platform for red dots, scopes, and backup sights. The Pac-Lite-compatible components include an accessory rail that requires drill & tap installation, an integral scope base with a built-in rear sight, and a standard scope base — each dimensioned to fit common sighting systems and to keep optics aligned with the barrel’s profile.

How does this mount attach to Pac-Lite barrels?

The accessory rail and scope bases are sized to interface with Pac-Lite barrels and require proper installation to ensure repeatable zero. One option requires drill-and-tap work by a competent gunsmith, while the integral base drops on and uses existing sight geometry.

• Accessory rail length: 2.63 inches (requires drill & tap service)
• Integral scope base length: 4.25 inches and includes a rear sight
• Standard scope base length: 3.4 inches for conventional mounting
• Designed to align with Pac-Lite barrel contours for consistent optic placement

What optics and accessories will fit this Picatinny rail?

The Picatinny profile accepts a wide range of optical sights and tactical accessories made to MIL-STD-1913 dimensions. From miniature red dots to compact magnified scopes, these bases provide a stable platform for most handgun and rimfire optics intended for Buck Mark setups.

• Fits MIL-STD-1913/Picatinny-compatible mounts and rings
• Accommodates micro red dots, reflex sights, and low-power scopes
• Integral rear sight preserves a backup iron-sight option
• Accessory rail enables lamps, lasers, or additional mounting hardware

Will installation affect accuracy or require gunsmithing?

When installed correctly, these bases are engineered to preserve barrel alignment and maintain consistent point of impact. The accessory rail specifically requires drilling and tapping, which should be performed by a qualified gunsmith to avoid damage and to ensure secure, repeatable attachment.

• Correct installation minimizes shift in point of impact
• Drill & tap service recommended for the 2.63" accessory rail piece
• Integral base includes rear sight to maintain sighting reference during optic changes
• Professional installation reduces risk of improper threading or misalignment

Which lengths and mounting choices are available, and what do they mean?

Tactical Solutions provides three distinct mounting options so shooters can choose the balance of rail length, sight integration, and installation method that matches their setup. Each length is specified to help select the right footprint for your optic and shooting needs.

• Accessory Rail — 2.63" length for compact accessory placement (needs drill & tap)
• Integral Scope Base — 4.25" including rear sight for combined optic and iron-sight use
• Standard Scope Base — 3.4" for a straightforward optics mounting footprint
• All bases are manufactured in the United States for premium fit and finish

Who is this for? The Tactical Solutions Buck Mark Picatinny Scope Rail Mount selection is aimed at Buck Mark owners who want a factory-quality mounting platform for optics and accessories on Pac-Lite barrels. Choose the accessory rail if you plan external attachments and have a gunsmith perform the modification; pick the integral base if you want an optics-ready solution that retains a rear sight; or use the standard scope base for a simple, compact mounting footprint. These choices suit target shooters, plinkers, and trainers who demand repeatable alignment and US-made components.
