Frequently Asked Questions
What is the difference between the "Short" and standard Double Decker Riser?
The Short Riser is a more compact version designed to minimize overall rail length while still achieving the 5/8" height increase. It's ideal for shooters who want to keep their optic positioned closer to the receiver or who are mounting shorter optics like compact red-dot sights. If you need additional rail space for accessories or a longer optic body, the standard-length version may be a better fit.
Will the Bobro Double Decker Short Riser allow me to use backup iron sights (BUIS)?
Yes. The Double Decker Short Riser features a 10-slot Mil-Std 1913 Picatinny rail that allows you to mount folding or fixed backup iron sights alongside your primary optic. This makes it easy to maintain an absolute or lower-third co-witness, depending on your BUIS height and optic combination.
Is this riser compatible with any Picatinny rail, or is it AR-15 specific?
While the Bobro Double Decker Short Riser is optimized for AR-15 and M16 flat-top receivers, it will mount to any standard Mil-Std 1913 Picatinny rail. This means it can also work on compatible rail systems found on other modern sporting rifles, shotguns, or chassis systems — as long as the host rail meets the 1913 Picatinny spec.
