This means you cannot tighten them evenly or as tight (25 vs. You know that squishy, sponge-like feeling you get when you tighten the receiver screws? How much is enough? When you tighten the screws on a wood or plastic stock, you are actually compressing the material between the receiver and the floorplate like a sponge. This all affects the way a plastic stock's mating surfaces supports the receiver and the barrel.Īluminum doesn't compress like wood and plastic. Also, mold temperatures rise and fall with production rates, slight product variations are the result. Mold engineers make calculations and complicated cooling fixtures to accommodate this as best they can, but it is never perfect because different parts of the stock will always harden at different rates. When a plastic stock falls out of the hot mold it changes shape as it cools. This results in high and low spots and reduced accuracy. When a wooden stock is being cut, the tools being used (especially if they are not sharpened frequently) can crunch, gouge and yank wood fibers from the wood, resulting in a less-than-perfect inlet.This is why you frequently see slivers of wood sticking up in the very areas that are supposed to be the most precise, under the receiver. ![]() Howa 1500/Weatherby Vanguard Stock and Barrel ComboĪluminum is more precisely machined than wood or plastic.
