MDT ACC Interior Forend Weights, 5 Pack

• Internal balance tuning: These weights add mass inside the forend, helping shift the rifle’s balance point forward for a steadier hold and more controlled recoil behavior on barricades, bags, and positional stages.
• Hidden installation: Because the weights sit in the interior barrel channel, they increase rifle weight without adding external bulk that can snag on gear or interfere with handling.
• Adjustable placement: Three mounting positions at 20mm (¾”) increments let the shooter fine-tune where the weight sits, making it easier to tailor balance to barrel profile, optic setup, and match preference.
• M-LOK clearance preserved: Clearance slots are built into the weights so compatible M-LOK accessories can still be mounted, allowing balance tuning without giving up forend utility.
• Quick chassis integration: The design allows installation and removal through the forend area without removing the barreled action, which simplifies setup changes between rifles, stages, or training sessions.

About the ACC Series

MDT ACC chassis systems were developed for shooters who want a rifle that can be tuned around balance, recoil control, and positional stability rather than kept as light as possible. In MDT’s lineup, the ACC series sits squarely in the competition-focused part of the range, especially for precision rifle disciplines where a planted rifle and repeatable handling matter as much as raw accuracy. The series is built around a modular chassis concept with broad scope for adding weights, accessories, and support equipment to suit the shooter’s technique and match format.

A defining trait of the ACC platform is its emphasis on weight distribution. Instead of relying only on external add-ons, the system supports internal and external weighting options so the rifle can be tuned for a neutral or slightly forward balance point. That matters in practical field shooting and competition because a well-balanced rifle tracks more predictably under recoil and settles more naturally on props and bags. The ACC family is therefore especially relevant to precision shooting setups where consistency, recoil management, and rifle control are priorities.

About the MDT ACC Interior Forend Weights, 5 Pack

The MDT ACC Interior Forend Weights, 5 Pack is a chassis accessory designed to change how an ACC rifle feels in use, not just how much it weighs on a scale. By placing mass inside the forend, this set adds 2.60 total weight while keeping the outside of the chassis clean and unobstructed. That internal placement is useful for competition rifles that need more forward bias to reduce muzzle movement, improve bag tracking, and help the shooter spot impacts more consistently.

Each weight is made from case-hardened steel and weighs 0.52 lbs / weight, including screws. The five-piece format gives more flexibility than a single solid insert because the shooter can decide how much weight to install and where to place it. With three mounting hole positions at 20mm (¾”) increments, the balance point can be tuned to match barrel contour, muzzle device, optic weight, or personal preference. This matters on rifles that are already highly optimized, where small changes in center of gravity can noticeably affect how the rifle settles on support.

The design also keeps the chassis practical. Clearance slots allow continued use of compatible M-LOK accessories, so adding weight does not automatically sacrifice mounting space. Installation is straightforward through the forend area, and the system is made specifically for the ACC Premier GEN1, ACC Premier GEN2, and ACC Elite chassis systems. For shooters building a dedicated match rifle, this accessory is a direct way to tune handling without changing the rifle’s external profile.

About MDT

MDT Sporting Goods was established in 2009 and began in Chilliwack, British Columbia, Canada. The company focuses on rifle chassis systems and related equipment for target shooting and hunting, with a product range that includes chassis, magazines, buttstocks, and accessories. MDT states that its products are developed with input from competitive precision shooters, which helps explain the practical, adjustment-focused design seen across its chassis ecosystem.

MDT identifies the TAC21 as its first chassis, and the brand has since expanded into a broad lineup of components intended to help shooters configure rifles around fit, balance, and application. That background is particularly relevant to accessories such as ACC weights, where the goal is not decoration but measurable changes in rifle behavior for precision shooting.
