Frequently Asked Questions
Will the Bobro Double Decker Short QD Riser truly return to zero after removal and remounting?
Yes. Bobro Engineering designed this riser with precisely machined indexing lugs that positively locate the riser in the same position on your Picatinny rail every time it is reattached. This mechanical repeatability means most shooters can remove and reinstall the riser — along with the optic — without needing to re-zero, making it ideal for setups where the optic is frequently swapped between rifles or stored separately.
What optics or scopes are compatible with this riser?
The Double Decker Short QD Riser is compatible with any optic mounted in a standard 30mm or 34mm ring set, or a flat-top scope mount that attaches to a MIL-SPEC 1913 Picatinny rail. It is commonly used to co-witness red dot sights, raise compact scopes for a better cheek weld on AR-style rifles, or position optics for use alongside night-vision devices. Always confirm your optic's objective lens clearance is sufficient for the elevated rail height before mounting.
How does the BLACR quick-detach system work, and does it require tools?
BLACR (Bobro Locking Ambidextrous Cam Release) is Bobro Engineering's proprietary QD lever system. A single lever motion — no tools required — locks or unlocks the riser from your Picatinny rail with positive engagement and a tactile confirmation. The lever is ambidextrous-friendly and designed to resist vibration-induced loosening, ensuring your optic stays put during sustained fire while still releasing instantly on demand.
