Bonding a picatinny rail to an action

[Veloci_Wrench]

Just reading through this. I’ve never epoxied a rail to a receiver. I see one person noted doing like bedding an action, which makes sense to me, given that it allows the rail to removed easily. However, I’m thinking the shear strength of the epoxy is what actually desired here as to not “only” rely on the screws securing the base to the action.

Is that the case, or is using a release agent on the receiver going to give the same added strength?

There is no added strength if you use a release agent. The goal is to bond the rail to the action, in order to decrease the likelihood of losing scope zero.

The only benefit derived from using a release agent is that you effectively glass bed your rail/action joint, which eliminates flex potential from unevenly machined surfaces ( i.e. it keeps everything level and square so that your scope tube is not torqued, bent, or put under tension when installed).

If you bond your rail the right way, you achieve both a "bedding" and a bonding.

Thanks! Makes sense to me. I’m not sure I’m ready to commit lol.
