Iver Johnson MF410 Features The Iver Johnson Arms MF410 is built around a semi automatic action chambered in .410 gauge with a 3 inch maximum chamber size giving shooters a lighter recoiling alternative to traditional 12 or 20 gauge tactical shotguns. The 20 inch barrel is finished in black oxide steel providing solid corrosion resistance along with a classic matte black appearance that stands up to regular handling and storage. Flip up front and rear sights come standard giving shooters an immediate aiming solution without requiring an optic and a dependable backup if a mounted optic ever fails. A black aluminum receiver features an integrated Picatinny rail giving the MF410 a ready made mounting surface for red dots or other optics without the need for separate mounting hardware. The forend is also equipped with a Picatinny rail expanding mounting options for lights lasers or foregrips to suit a tactical or home defense setup where quick target identification and control matter. An adjustable cheekrest polymer stock allows shooters to dial in proper cheek weld particularly useful when running a mounted optic and ensuring a consistent sight picture shot after shot. Internal choke tubes allow some flexibility in shot pattern depending on the intended use letting the MF410 adapt from close range home defense to broader pattern applications while sling swivel studs support use with a tactical sling for hands free carry. At just over 7 pounds and feeding from a 5 round capacity the MF410 offers a lightweight fast handling tactical shotgun option in a reduced recoil chambering that suits new and experienced shooters alike.
