Trijicon® 45° Rail Offset Adapter – RMR® / SRO™ Secondary Optic Base – Aircraft Aluminum – AC32066
The Trijicon® 45° Rail Offset Adapter (AC32066) is a premium, duty-grade tactical optic mounting accessory engineered to facilitate seamless transitions between long-range target tracking and close-quarters engagement lines. While standard primary riflescopes or high-magnification optics provide vital performance over distance, they leave operators vulnerable and visually choked during sudden close-in threats due to a restricted field of view. This low-profile offset adapter (719307613102) resolves that tactical dilemma, establishing a dedicated 45-degree secondary mounting deck that allows for instant reflex aiming with a simple, natural wrist rotation of the firearm.
Precision CNC-machined in the United States from lightweight, high-tensile aircraft-grade aluminum, the AC32066 chassis is protected by a rugged, non-reflective matte black hardcoat anodized finish. This advanced coating resists heavy field friction, aggressive skin acids, and abrasive cleaning solvents. Weighing a mere 1.15 ounces and measuring just 1.25 inches in longitudinal length, this micro-stabilizer adds virtually zero weight to your weapon snout. The technical hallmark of this configuration is its ultra-slim, compact base structure. Its low-height clamp footprint allows it to slide cleanly underneath almost any primary variable riflescope or ring assembly without requiring you to tear down or re-zero your primary glass. It sits perfectly in front of or behind your primary optics, such as a Trijicon ACOG® or VCOG® setup.
The true functional highlight of this factory-engineered asset is its **fully ambidextrous architecture**. Built with symmetrical tracking lugs, the adapter can be flipped around and mounted to face either the left or right side of the weapon receiver, accommodating both left- and right-handed operators. Engineered to clamp onto standard MIL-STD-1913 Picatinny rails via an integrated crossbolt key, this unyielding physical anchor provides an absolute return-to-zero hold that withstands heavy muzzle blasts, aggressive barrier driving, and drop testing. It stands as a reliable, combat-ready configuration choice for personal defense weapons (PDWs), patrol carbines, and special purpose rifles (SPRs).
Includes: (1) Trijicon 45° Rail Offset Adapter Mount Chassis (Matte Black), (1) High-Tensile Steel Crossbolt Clamp Assembly, and (1) Steel Alignment Rail Key.
*Direct Footprint Integration Note: This component terminates in a short 1913 Picatinny rail section at a 45-degree cant. It does NOT feature pre-drilled RMR threaded post holes on its bare top face. To successfully mount your Trijicon RMR or SRO reflex sight to this adapter, you must couple the optic with a Picatinny-compatible low-mount base plate (such as the Trijicon RM33 or equivalent aftermarket rail mount).
Key Features
- Ambidextrous 45° Offset Deck: Configures your reflex sight at a precise 45-degree angle on either the left or right side of the handguard to accommodate any shooting style.
- Sleek Under-Scope Clearance: Ultra-low profile clamp design slips easily under large riflescope main tubes and windage turrets without forcing changes to your primary optic's height.
- Micro Lightweight Footprint: Takes up only 1.25 inches of linear rail space and weighs just 1.15 ounces, preserving your handguard's balance and tracking speed.
- Mil-Spec Anodized Armor: Monolithic aluminum block is treated with a Type III hardcoat anodized finish to shrug off severe field scuffs, salt air, and chemical solvents.
- Integrated Steel Index Key: Utilizes a dedicated steel rail key inside the locking clamp assembly to ensure a rock-solid, recoil-proof bite onto your receiver.
- Elite American Craftsmanship: Proudly engineered, machined, and surface-treated in the USA to guarantee flawless performance in demanding duty environments.
