Looking to upgrade you rifle?
Adding a Arca rail to it provides that versatility to shoot from tripods and adapt your shooting position whatever the terrain imposes. 
Keep in mind there are 4 sizes.
Personally I would choose the longest one that would fit the M lock section. A short section provies you with less mounting locations.
All hardware is uncluded to mount these to your M-Lock section
