Mdt Sporting Goods Inc Interior Forend Weights Features The Mdt Sporting Goods Inc Interior Forend Weights are machined from case hardened steel so they add durable concentrated mass exactly where the shooter wants it inside the ACC Chassis forend. Because each weight ships with three sets of mounting holes it can be repositioned inside the barrel channel at 20mm increments giving fine control over how far forward or rearward the added weight sits. That adjustability lets a shooter fine tune the rifle s balance point for prone bipod or barricade positions rather than accepting a single fixed weight distribution. Sold as a 4-pack at .52 lb each the set offers real flexibility in how much total mass is added to the front of the rifle. Despite adding weight to the forend these inserts are designed with clearance slots on the underside and sides so M-LOK accessories can still be mounted to the ACC Chassis forend with the weights installed. That means a shooter does not have to choose between tuning balance and running a bipod light or other M-LOK accessory up front. The steel construction stands up to the recoil and handling of a dedicated precision rifle without loosening over time. For competitors and long-range shooters refining an ACC Chassis build these forend weights are available for sale at GrabAGun.
