The 5D Step palm-shelf from Shooting Equipment is a multi adjustable support for shooting standing with Sport and Free rifles.
The compact construction provides 20mm of adjustable fore-end elevation, which can be extended to 50mm with the optional spacers.
The unit can also be moved laterally, and rotated in a variety of directions, allowing the shooter to move the stock closer to, or further from, their body. The various options mean it can be used with either a supporting fist, or held in the palm of the hand.
Fits all standard accessory rails.
