The forend can be a huge part from a “looks” and a functionality perspective for the AR-15 rifle or other variants (pistol, carbine etc.). The style of forearms is a constantly evolving market metric. Some forends offer better optic placement, room for additional gripping surfaces or the ability to add on some extreme functionalities. Materials are also a very important part of the selection process for a forend on the AR-15 or clones. The market has evolved to offer many traditional materials, like aluminum and steel and lined plastics, to include more exotic (for the platform) choices like composites, including carbon fiber or non-traditional wood furniture.
