Eastern Tactical Supply PT35-138-20MOA: 35mm Tube, 1.38in Height, 20 MOA Picatinny Rail Mount

Overview

Meet a rugged, purpose-built mount designed for Picatinny rails and long-range capability. This one-piece mount centers a 20 MOA cantilever on a 35mm tube geometry, delivering a stable platform for a wide range of rifles and optics. The spacings and clearances are tuned to align with typical two-ring setups, helping shooters achieve repeatable positioning under field conditions.

Constructed to support demanding recoil profiles, this mount emphasizes solidity without unnecessary weight. With a center-to-base height of 1.5 inches and a base length of 3.9 inches, it maintains a low profile while offering enough clearance for proper eye relief and optic clearance on many rifles. The ring spacing of 3.2 inches is designed to balance the weight distribution and tracking accuracy across a typical long-range setup.

Key specifications

• One-piece 35mm/34mm tube scope mount with 20 MOA cantilever for improved long-range holdover.
• Ring spacing 3.2 inches; center-to-base height 1.5 inches; base length 3.9 inches.
• Made from durable 6061-T6 aluminum alloy for a sturdy, lightweight build.
• Shockproof heavy-duty 4-bolt screw design supports high recoil rifles.
• Compatible with 21mm standard Picatinny/Weaver rails for broad fitting options.

Durability and material quality

The mount is machined from high-grade aluminum alloy to withstand the rigors of field use. The combination of a robust 4-bolt attachment and a shockproof design helps keep the optic stable during rapid fire or heavy recoil, while the aluminum’s natural rigidity contributes to repeatable zero maintenance over time.

Installation and retention

• Built-in cushioning tape inside the scope rings reduces movement and helps prevent slippage during mounting and shooting.
• Includes mounting hardware for straightforward setup: 1 pair of 34mm 20MOA scope mounts and 1 Allen key, ensuring you have what you need to get the job done.

Real-world use and benefits

Ideal for setups where a cantilever mount is preferred, whether you are prepping for precision matches, field testing, or versatile hunting configurations. The 20 MOA provides extra adjustment range, and the overall profile is designed to support stable aiming with a variety of optics. While this description highlights potential advantages, there are no guarantees—results will vary with other components and conditions.
