BadAce Picatinny Rail – 20 MOA for CZ 452/455/457, Tikka T1x & Anschutz (11 mm Dovetail)

The BadAce 20 MOA Picatinny Rail is a precision-machined optics mounting base that converts an 11 mm dovetail top on specific rimfire rifle models into a standardized Picatinny rail with a 20 MOA forward cant. This incline helps shooters retain more elevation adjustment on their scopes — particularly useful for longer-range rimfire shooting — and opens up a wider range of accessory compatibility than raw dovetail mounts allow.

Key Features

Rifle Compatibility:
• Designed to fit rifles equipped with an 11 mm dovetail receiver width — including CZ 452, CZ 455, CZ 457, Tikka T1x, and certain Anschutz models that use the same dovetail standard. It does not fit rifles with the wider 3/8″ dovetail or other proprietary dovetails.

20 MOA Built-In Cant:
• The rail’s 20 MOA forward angle gives your scope a downward alignment relative to the bore, allowing the optic to stay closer to the center of its elevation adjustment range — especially helpful when shooting at extended distances with .22 LR or similar rounds.

Picatinny Standard Interface:
• Converts the rifle’s dovetail to a MIL-STD-1913 Picatinny rail, making it easy to mount a broad variety of scope rings, red dots, backup sights, or other Picatinny-compatible accessories.

Secure Attachment:
• Four screws clamp the rail firmly to the dovetail slot for a stable, repeatable mounting surface that resists movement under recoil.

Easy Installation:
• The rail slides onto the rifle’s dovetail and is tightened in place — no gunsmithing or machining required, provided your rifle’s dovetail is compatible with the 11 mm specification.

Technical Specifications

This rail does not include scope rings or optic hardware.

Performance & Practical Use

Converting your rifle’s 11 mm dovetail into a Picatinny platform gives you much more flexibility when choosing optics — it lets you mount a wider selection of scope rings and sighting systems that are otherwise unavailable for direct dovetail mounting. The 20 MOA cant built into this base helps maximize usable elevation travel on many scopes, particularly for rimfire rifles where external ballistics require more drop compensation at extended distances.

The rail’s stable clamp-on design requires no permanent alteration to your rifle, and tightening the included screws keeps the rail in place under normal recoil forces. This makes it a practical upgrade for target shooters, varmint hunters, and rimfire enthusiasts seeking improved optics flexibility and long-range capability on platforms like the CZ and Tikka series.

Best Suited For

✔ .22 LR shooters planning to mount scopes with broader elevation adjustment needs
✔ Rimfire rifles with 11 mm dovetail receivers that lack a Picatinny rail
✔ Users who want to mount standard Picatinny scope rings or accessories
✔ Shooters expanding their setup for longer distances where optic elevation is critical

User Tips

Verify Your Dovetail Size:
Measure the width across your rifle’s receiver dovetail — if it’s larger than 11 mm (roughly 7/16″), this rail won’t fit. A wider dovetail (like 3/8″) requires a different mount.

Match Your Scope:
If you plan to shoot at a wide range of distances, check your scope’s elevation travel — combining a 20 MOA base with a scope that has limited adjustment can help keep zeroing within a usable range.

Proper Torque:
When installing the rail, tighten screws evenly to avoid uneven pressure on the dovetail and ensure stable alignment for optics.
