We carry "Featureless" parts for your AR-15 that help build compliant rifles in restricted states. Certain states like California, New York, Connecticut, Hawaii, Massachusetts etc., restrict users from building AR15's without some sort of featureless grip, fixed magazine, bullet button, or other devices that would help keep your rifle compliant. Some of these products include featureless stocks & featureless grips.
Most states that impose these unconstitutional restrictions are unclear about the exact combination of parts that would keep your rifle legal, so we cannot recommend certain parts that would keep you legal. Please check with your local and state laws to make sure that you build a legal rifle or pistol. We are not lawyers and we do not keep up with laws that are not imposed on a federal or local level.
There are plenty of other parts in other categories that can be used to build a featureless rifle or pistol. These are just parts that stick out.
