Why use a riser like this?
Good question. Some uses beyond simple clearance include:
-
Mounting large objectives on compact rifles or barrels so they don't contact handguards
-
Aligning scopes with raised cheek welds, face shields, or NV/thermal overlays
-
Stacking optics, lights or other accessories without interference
-
Use in bench or supported shooting where height helps positioning

Will it affect zero or alignment?
If mounted properly—level, firmly clamped, using the cross‑slot stop, and screws torqued correctly—it should maintain zero. Be sure to use the correct torque (we recommend max 18 in‑lbs) and check alignment after installation.
How heavy is it and how much does it add to your rig?
It’s relatively lightweight for its size (~79 g) thanks to cut‑outs and slim design. While it adds height and weight, for large optics or tactical setups it’s often a worthwhile trade for improved ergonomics and clearance.
Is it compatible with all Picatinny rails?
Yes — it's designed for standard 20 mm Picatinny. Make sure your rail is flat and in spec. Older or non‑standard rails may have slot width differences that affect fit.
