The Mossberg 510 Mini Super Bantam is a 20-gauge pump-action shotgun sized specifically for youth and smaller-framed shooters. At 5 lbs with an 18.5-inch barrel and Mossy Oak Break-Up Country camo finish, it is one of the lightest and most compact options in this gauge.

Detailed Features 

 
Stock spacers adjust length of pull between 10.5 and 11.5 inches, which accommodates young shooters as they grow without needing a different gun. The ambidextrous tang safety at the top of the receiver is accessible for both left and right-handed use. Dual bead sights keep the aiming system simple. The 3-inch chamber handles both standard and heavier field loads. The camo finish covers the stock and barrel for concealment in hunting situations. 
 
The short LOP range and 5-lb weight make it genuinely easy for a small-framed shooter to mount and hold steady.

The 510 Mini's user feedback is dominated by parents who bought it as a first hunting gun for children. The consensus is that the fit -- particularly the 10.5-to-11.5-inch LOP range -- works where standard youth guns still feel too long. The light weight draws specific praise for reducing the fatigue that can make beginners reluctant to practice.

The camo finish is appreciated by hunters for practical concealment and by kids who want a gun that looks purposeful rather than toy-like.

Recoil comes up sometimes: the 20 gauge in a 5-lb gun is more noticeable than in a heavier platform, and some parents note that reduced-recoil loads help younger or recoil-sensitive shooters stay on target. This is a tradeoff the gun's design acknowledges by being 20 gauge rather than 12.

Overall sentiment is positive for the intended use case.
