Get the added stability and tracking benefits of a 4” wide stock by adding these to your 3” stock!
They are 6061-T6511 AL, CNC machined, 6” long and will make a 3.00” forend 3.984” wide when installed. Rails are .490” tall x .50” wide - purposely under the IBS rule limits. The installed rail depth is .260”. There’s a shelf machined into them to aid in location and to take the shear load off of the fasteners. Each rail bolts on with two #8-32 SS SHCS and anchors (included).
The rails can be installed by a handy DIY type, or any competent gunsmith. Requires a 4” front bag. Can be easily removed if you switch from Long range benchrest to F-Class, for example.
