This is a simple yet effective bipod for my arisoft sniper ASG Zastava Varmint M70.
I made this using Solidworks 2016 and it works very good until now.

It could be used on any sniper rifle like VSR10,Varmint M70 etc or with any sniper rifle/airsoft gun that has a M5 Threded hole on its bottom part.

Estimated cost: Approx: 10$
