Cayugad, the X7's barrel is secured to the stock with two screws in the location shown in the pictures. The barrel is pretty much free floating.





The gun grouped very well when new. But after I'd put a few hundred rounds through it the accuracy started falling off. I think the barrel settled in the stock because even with the two mounting screws tight I could move the barrel side-to-side a very slight bit. I put a little bedding compound of each side of the barrel - strips about an inch long and half-inch wide located about midway between the mounting screws. That tightened the groups up nicely, but I'm thinking of a full bedding job.

Sabotloader, thanks for that link. Interesting article.
