*Pluck foam is scored so you can customize it to fit your gun, scope, mounts, mags, bipod, ammo box and more. The pluck foam is 46" long in the case. That's all that can be removed to accommodate items. There's non-pluck foam that extends out to cover the total 51.5" interior. The No. 1 thing you want from your gun case is total protection for your gun and optics. Plano's All-weather line of tactical hard cases does that…and more. The ability to carve out a fitted section in the customizable pluck foam for your rifle, scope, bipod and ammo is a really big deal since that will help prevent accessories and ammo from hitting or damaging your gun.
