The Primary Arms SLx 34mm Cantilever Scope Mount is a durable, great-value one-piece mount for 34mm scopes on Picatinny rails. The 1.5in height gives a standard optical centreline for LPVO and rifle-scope builds, with the forward cantilever setting correct eye relief on AR-pattern rifles.
The SLx line delivers PLx-style mounting function — a rigid one-piece body and secure multi-bolt clamping — at a more accessible price.
