The CSR Precision picatinny rail is a picatinny accessory rail that fits the stock hand guard of the SIG SG550/PE90/Fass90/Stgw90. This accessory rail replaces the original bipod and enables you to fit other bipods or a light to your SIG.
Unlike other solutions on the market this rail actually enables you to mount bipods like the B&T polymer bipod, which protrudes underneath the bayonet lug.
The rail is CNC machined from 7075 aluminium and mil-spec anodized in matte black.
