Bobro Engineering has introduced the QD Double-Decker Riser in EXTRA LONG, developed from user feedback. This 24-slot riser allows for multiple optics and accessories on a single rail while ensuring a perfect return to zero. Its T beam construction provides rigidity, and QD levers enable quick swaps without losing zero.
Bobro Engineering states “The QD Double-Decker extra-long came about by user input. We were asked if we could make a riser that would act as a “top end” of sorts. The extra length and return to zero allows a user to mount a host of compatible optics/lights/lasers on a single rail section, allowing a complete configuration swap on a single weapon. After rigorous testing and prototyping, we found the perfect length (24 rail slots) that allowed for a flawless return to zero while remaining stiff enough to have zero flex and enough room to mount an optic, magnifier, and laser combo. The riser utilizes a T beam construction to remain rigid and maintain straightness. The QD levers allow the entire top end assembly to be swapped in seconds while perfectly holding zero.”
