Kizuna Works Steel RMR Optic Mount for BSK43 Gas Blowback Airsoft Pistol, Black

Most of the optics that come on budget blowback pistols shift zero the moment the slide starts cycling. Kizuna Works built this mount for the BSK43 specifically, and the only thing it does is keep your red dot where you left it.

Steel instead of polymer. Machined from steel, which matters on a gas blowback pistol because the slide is slamming back and forward every shot. A polymer mount flexes under that motion and your point of impact creeps. Steel does not. You zero it in and it stays there.

Low profile for a compact pistol. The mount sits close to the slide surface, so the optic does not add height where you do not want it. On a small GBB like the BSK43, keeping the sight line clean and low matters for quick target acquisition and comfort behind the iron.

RMR-style mount. Designed for RMR-compatible micro red dots. Verify your optic's footprint against the mount before purchase.

Before you buy. The optic is not included. You need a compatible micro red dot with the matching footprint, plus whatever tools your optic requires for windage and elevation adjustment.
