What rifles and support platforms are compatible with the Spartan HD Disc-Lok Adapter for Picatinny?

This adapter features a quick-detach lever clamp designed specifically to mount heavy precision rifles onto standard MIL-STD-1913 Picatinny accessory rails. On the support side, it integrates with Spartan Disc-Lok attachment systems, such as the Spartan Hercules tripod head, providing a rock-solid connection for heavy-duty setups.

Is this 214 g adapter suitable for mobile backcountry hunting where pack weight is critical?

At 7.5 oz / 214 g, the HD Disc-Lok unit is engineered for PRS and ELR competition rather than ultralight weight savings. Mobile backcountry hunters prioritizing minimal pack weight on light sporter rifles should instead consider Spartan's standard ultralight magnetic adapters, which typically weigh between 20 g and 30 g.

What materials are used in the construction of the SPAR02035R, and how does it handle harsh outback environments?

The adapter is CNC-machined from robust 7075-T7351 aerospace-grade aluminium billet and SUS303 stainless steel components. Finished with a hard-anodised black coating, it provides high corrosion resistance and structural durability for demanding use across alpine, desert, and wet Australian outback conditions.

Does the adapter allow for horizontal traverse adjustment when mounted?

Yes, it includes an integrated traverse friction control lever and knob. This allows shooters to easily adjust horizontal panning tension from smooth movement across moving targets to a rigid, full lock-off for long-range precision shots.

Picatinny Rail Adapter - Spartan SPAR02035R

The Spartan Precision Equipment HD Disc-Lok Adapter for Picatinny connects heavy tactical, match, and hunting rifles to Spartan Disc-Lok support platforms, such as the Spartan Hercules tripod head. Engineered for high-energy platforms, this heavy-duty mounting hardware utilises an ergonomic quick-detach (QD) lever clamp to secure directly onto standard MIL-STD-1913 Picatinny rails. The integrated friction control mechanism enables shooters to adjust horizontal traverse tension, transitioning from smooth panning across moving targets to rigid lock-off for long-range stationary shooting.

Quick-Detach Interface: Ergonomic QD lever clamp allows rapid attachment and removal from MIL-STD-1913 Picatinny rails.
Traverse Friction Control: Integrated control lever adjusts horizontal panning resistance from fluid tracking to complete lock-off.
High-Energy Recoil Stability: Built to absorb heavy recoil and support substantial rifle weights on Spartan 16 mm Disc-Lok spigot systems.
Corrosion-Resistant Construction: CNC-machined from 7075-T7351 aerospace-grade aluminium billet with SUS303 stainless steel components and a hard-anodised black finish.

Who is the Spartan HD Disc-Lok Picatinny Adapter for?

Precision rifle series (PRS/NRL) competitors — relies on the 7.5 oz (214 g) CNC-machined 7075-T7351 aluminium and SUS303 stainless steel construction to maintain rigid tracking and positional stability under heavy match rifle recoil.
Extreme Long Range (ELR) and tactical shooters — utilizes the integrated 16 mm Disc-Lok spigot interface and horizontal traverse friction control to securely lock heavy Magnum chamberings onto tripod heads without mechanical slip.
Stationary big-game tripod hunters — mounts heavy rifles to stationary tripod platforms via the MIL-STD-1913 Picatinny quick-detach clamp for high-stability field glassing and shooting setups.

Less suitable for: Mobile backcountry hunters prioritising minimal pack weight who are better served by ultralight magnetic spigot adapters weighing 20 g to 30 g, or shooters running dedicated Arca-Swiss rails who require a dedicated Arca-compatible adapter rather than a MIL-STD-1913 Picatinny clamp.
