Telescoping Stock

A telescoping stock is a rifle buttstock that can adjust its overall length to allow a better fit for the shooter or a more compact firearm when needed. The military M4 and the civilian AR-15 rifles generally feature telescoping stocks. There is a wide range of telescoping stocks available for AR-style rifles that have different features tailored to individual shooters and their needs. Some states have regulations prohibiting the use of telescoping stocks on certain rifle styles.
