AR-15 parts FAQs
Do AR-15 parts ship to my house? Yes — every part except a serialized receiver ships directly to your door.
What upgrades matter most? A better trigger, quality optic and reliable BCG produce the biggest improvement per dollar.
Are parts mil-spec compatible? Product pages list mil-spec or commercial fitment so buffer tubes, stocks and pins match your rifle.
