Brno Combo Picatinny rails

Brno Combo Picatinny rails convert the receiver dovetail into a universal Picatinny base so you can use modern rings, one-piece mounts, and red dots with Picatinny adapters.

Why add a rail?

• Universal interface: easy pairing with today’s optics and accessories.
• Repeatable zero: cross-slots resist shift and make optic swaps straightforward.

Fit & material

• Model-specific: choose a rail made for the Brno Combo. Verify the dovetail size (often 11 mm or 16 mm) or whether your variant needs a screw-on receiver/rib mount.
• Aluminum vs. steel: aluminum saves weight; steel maximizes rigidity and thread strength.

Install tips

• Degrease rail, receiver and screws; apply Loctite threadlocker.
• Torque to spec in a criss-cross pattern; witness-mark and recheck after the first range session.
• For clamp-on rails, seat evenly on the dovetail and verify no movement before final torque.
