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.
