I hve my AI bipod for sale. It's in mint condition having hardly been used. The rifle has only ever fired 80 rounds and the bipod was in the drag bag for most of these!
It comes in mint condition as stated, complete with rubber covers for the feet, as well as the friction lock, which tightens the spigot into it's fitting, reducing cant.
These three components retail at approx £300 from Sporting Services, where I bought them from as part of my rifle build.
Selling for £195 delivered to any UK mainland address.
