MDT Bolted ARCA Rail, 6''

• ARCA interface for tripod support: Adds a 6'' ARCA/RRS-compatible mounting section so a rifle can be moved quickly between tripod, bipod and other support gear while keeping a secure, repeatable connection.
• Flat, low-profile design: The slim shape keeps the underside of the rifle smooth and comfortable in positional shooting, while still giving long fore-aft adjustment for balance on a tripod.
• 26 drilled and tapped holes: Multiple mounting points let accessories be indexed consistently, which helps maintain a familiar setup and makes it easier to place support equipment exactly where it works best.
• Rearward overhang and angled front: The rear extension helps position the rifle closer to its center of gravity on a tripod, while the angled front guides the clamp into place and reduces snagging during fast handling.
• 6061-T6 aluminum construction: The aluminum body and hard-anodized finish keep weight reasonable while standing up to repeated mounting, recoil and field use.

About the ARCA Rail Series

MDT ARCA rails are built for shooters who want to add a modern support interface to a rifle chassis, stock or handguard without changing the rifle’s core setup. In MDT’s accessory range, these rails sit alongside the company’s chassis, magazines and support components, giving precision rifle and hunting rifle users a practical way to integrate tripods, bipods and other ARCA-compatible equipment into a field or match rifle.

The series is defined by a focus on stable support mounting, repeatable accessory placement and a shape that remains comfortable when the rifle is carried or shot from improvised positions. Depending on the mounting standard of the host rifle, MDT offers ARCA rails for different interfaces, but the design philosophy stays consistent: a strong aluminum rail, a hard-wearing anodized finish and geometry that supports smooth engagement with clamps and adapters. For shooters building a more versatile rifle support system, the series provides a straightforward bridge between traditional chassis platforms and the now-common ARCA/RRS standard.

About the MDT Bolted ARCA Rail, 6''

The MDT Bolted ARCA Rail, 6'' is a compact bolt-on accessory designed for rifles that use Magpul MOE-spaced tapped holes on the underside of the forend or handguard. Rather than replacing the host chassis or adding a bulky adapter, it creates a clean 6'' mounting surface for ARCA-compatible tripod heads, bipod clamps and other support accessories. That makes it especially useful for precision shooting, prone work and tripod-supported field positions where balance and fast repositioning matter.

Its practical value comes from the way MDT has shaped the rail for real rifle handling. The flat profile keeps the rifle comfortable in the hand and less obtrusive when shooting unsupported. The rearward overhang helps move the tripod attachment point closer to the rifle’s center of gravity, which can improve stability and reduce the tendency of the setup to feel front-heavy. At the front, an angled leading surface helps guide the clamp onto the rail more smoothly, while rounded edges reduce pressure points during standing or barricade shooting.

MDT also builds this rail with long-term use in mind. The 6061-T6 aluminum body and Mil-spec Type II hard anodized finish are intended to handle repeated mounting and field wear, while the 26 drilled and tapped holes give flexible indexing options for accessories. Because MDT machines and checks its dovetails to the Really Right Stuff standard, the rail is aimed at shooters who want dependable compatibility with ARCA-style support gear.

About MDT

MDT Sporting Goods was established in 2009 and began in Chilliwack, British Columbia, Canada. The company focuses on equipment for target shooting and hunting, with a product range that includes rifle chassis systems, magazines, buttstocks and accessories. MDT identifies the TAC21 as its first chassis, and that early emphasis on modular rifle platforms still shapes the brand’s product line today.
