Built specifically for the MDT ACC Rifle Chassis, the company's Internal Forend Weights are sold in sets of five, each weighing 0.52 pounds, while the company's ACC chassis has the ability to hold up to five weights, giving users the ability to add up to 2.56 pounds to their rifle. Three separate mounting holes inside the forend channel allow users to fine-tune where the weights are mounted inside the chassis, so the balance point of the gun can be shifted slightly with each weight. All of the rifle weights are machined from steel and feature machined clearance slots that allow users to continue mounting M-LOK accessories, even with weights installed.
