B-31N upper hand guard. This part has a B-30 (Lower extra long hand guard) pre-requisite part, necessary for B-31S to be able to work.

This part is similar to B-31S, but B-31N has slightly lower profile.


NOTE: B-31N will work on both, standard 16 inch AK-74/AK-100 as well shorter AK-105/AK-104 style rifles. Shorter rifles employ a combo gas block which is shared with front sight base. If you have any doubts as per what part you need, feel free to contact us. We will gladly assist you.
