Vertebrae Picatinny rails

Take care of firearms safety. Why do we even have to write this? Well, people make mistakes. We do however believe that safety is ensured by always adhering to the philosophy of “always considering the gun to be loaded”, and then acting as if it were.

We provide our customers with 4pcs of 6-48 3/8” socket head screws along with our picatinny rails. They might not necessarily be a perfect fit for your rifle. When mounting the screws check that they do not protrude into the mechanism. On the rails with an MOA/Mil angle, it is likely that the front screws may enter the bolt lug area.

If this happens mark the excess screw length with a magic marker and either cut or file away the part of the thread marked until function is verified.
The rail should fit nicely on the receiver and not bind in any way when tightening the screws. Pull the rail slightly forward when testing the fit. Once happy with the setup you can add a slight touch of Loctite under the rail and a small drop on each screw before torqueing down the screws. This is mostly to prevent any moisture to accumulate between the rail and receiver.

On some rails, such as for the Tikka we supply steel recoil pins, they can use Loctite to ensure a snug fit in the receiver.
Use finger torque, or tighten the screws down w with an Allen key, using the short end of the key. The threads are in the receiver, and the force required is usually low. Refer to the manufacturers recommendations.
