Product Summary

Start your young shooter out right with Mossberg's most compact pump-action shotgun. At just 5 lbs. and about 34" long, it's not too heavy or large for youth shooters to enjoy. The buttstock is designed for length-of-pull adjustments with stock spacers, allowing the 510 to grow with your child. Inside, a combination of dual extractors, twin action bars, positive steel-to-steel lock-up and anti-jam elevator work to ensure smooth and reliable cycling. The EZ-Reach forearm and shortened pistol grip enhance overall control and shooting comfort. This shotgun features a ventilated rib, front and rear bead sights, a tang-mounted safety, and a cylinder choke tube. Its stock, metal, and bore are all in very good condition.
