The Primary Arms PLx 30mm Cantilever Mount – PA-PLX-CM-30-1.5 is the top-tier mounting solution for shooters demanding uncompromising performance from their optics setup. Part of the PLx premium product line, this mount is crafted from 7075-T6 aluminum, a material significantly stronger than standard 6061 aluminum, and is finished with a Type III hardcoat anodizing for long-lasting protection.
With a 1.5″ centerline height, this mount provides optimal cheek weld and eye alignment on AR-style platforms. The cantilever offset pushes your optic forward, delivering the correct eye relief for low power variable optics (LPVOs) and precision scopes, especially on short upper receivers.
Engineered for durability, it features reinforced steel cross-bolts, steel-threaded ring inserts, and tight tolerances to maintain zero through recoil, transport, and hard use. Whether you’re setting up a competition carbine or a duty-grade rifle, this mount offers the rock-solid stability needed for serious performance.

FAQ:
Q: What is the benefit of 1.5″ centerline height?
A: It ensures natural alignment with standard AR-15 cheek welds and is compatible with absolute co-witness optics setups.
Q: Is this mount compatible with any 30mm scope?
A: Yes — it is made for all 30mm tube scopes, including LPVOs and magnified optics.
Q: How does this differ from the SLx mount?
A: The PLx version is built from stronger 7075-T6 aluminum, offering superior rigidity and long-term durability.
Q: Will the forward offset throw off zero?
A: Not at all — the cantilever design simply adjusts optic position. The steel cross-bolts ensure repeatable zero retention.
