The two feet may to use, be up or folded down easily and without any additional button or similar.
Of course you can / may this bipod remain mounted if required during shooting as weight (80g) at the gun! (ISSF-conform !!!)
Mounting at the rifle without tool!! 

Feet are longer than at the most other bi-pods on market - so the barrel gets no contact to the ground !! (from bottom till stock = 10cm)

Special plastic-rings and glue-fixed screws hold the feet in position.

A bipod facilitates the rebuilding and cleaning the weapon and prevents scratches on the stock or damage to the bolt when the rifle is otherwise placed laterally.
Suitable for stocks from: Feinwerkbau (FWB), Anschütz, AHG, Walther, MEC, TESRO, Grünig & Elmiger, Bleiker,TEC-HRO ...

Attention: new ISSF-rule up from 2017: bi-pods whether fixed or folding must be removed from the rifle during match firing times
