Tallest buttplate at a reasonable price - Mission First Tactical Battlelink Minimalist Stock Military For Mil Spec Size 1.148 Diameter Receiver Extensions Gray BMSMILGY

Prefer this over all other ar-15 stocks, because the buttplate is the tallest you can buy, allowing the rifle to be mounted higher on the shoulder. This is only important for tall people, or people with a long neck. The buttplate extension does not feel flimsy, but I'm sure if you smashed it against a rock it would break off.
