Tier One 300x20mm Picatinny Riser Sand
The Tier One 300x20mm Picatinny Riser raises the scope to a better height for line of sight on AR-pattern rifles. It is machined from a solid billet of 7075-T6 aluminium on five-axis CNC to a tolerance within 3 microns, and made entirely in house by Tier One. It gives a 300mm rail length for flexible scope placement and eye relief. This is the fixed version in sand, supplied with all the mounting hardware.

Installed the riser on my AR15 and noticed a significant improvement in scope height. The fit is precise and the rail stays stable during shooting. No wobble or play, which is great for accuracy.
Piers Davies –
The sand finish looks solid and feels durable. It fits well with my existing rail system. The 300mm length gives me more flexibility in scope positioning.

High precision machining is evident. The tolerance is tight and the riser sits flush with the receiver. Works perfectly with my red dot scope.
