MDT ACC | INTERIOR FOREND WEIGHTS | 5-PACK
Add Weight Inside. Keep Your Mounting Options Outside.
The MDT ACC Interior Forend Weights, 5-Pack — 104059-BLK add mass inside a compatible ACC forend. Adjust your chassis setup without using exterior accessory positions for every weight you add.
A chassis gives you the foundation. Weight placement helps you tailor how the completed rifle feels. This five-piece internal forend weight kit is intended for compatible MDT ACC chassis configurations, giving you another way to adjust forward mass as the rifle’s equipment changes.
Put the Weight Where Your Setup Needs It.
An optic, bipod and other accessories all contribute to the balance of a completed rifle. Internal forend weights provide a way to add mass toward the front of a compatible ACC chassis rather than adding it at the buttstock.
Choose weight placement around the rifle you actually use. More weight is not automatically a better setup; the useful combination depends on your equipment, shooting position and preferred balance.
An Internal Approach to Chassis Weight.
Interior weights occupy the chassis’s designated internal mounting area. That makes them a different option from exterior M-LOK weights, which mount to compatible slots outside the forend.
For shooters using both types, internal and exterior weights serve different mounting needs. Check the chassis’s available positions and clearance before planning the complete arrangement.
Check the part number before ordering. This listing is for 104059-BLK, the ACC interior weight five-pack.
MDT also offers a separate ACC Gen2 interior weight four-pack, 110007-BLK. These are different kits. Confirm the correct kit for your exact chassis model and generation rather than relying on the ACC name alone.
