'Rust' Armorer Hannah Gutierrez-Reed Lawyer Says Sabotage Designed to Frame Her

Hannah Gutierrez-Reed -- the armorer for "Rust" -- is doubling down, claiming she was targeted for sabotage and she thinks she's now being framed ... this according to her lawyer.

Gutierrez-Reed's attorney Jason Bowles tells TMZ ... "We are convinced that this was sabotage and Hannah is being framed." This is a step beyond what Bowles said earlier in the week ... he alleged sabotage, but didn't say it was targeted at his client.

But, Bowles wasn't done ... he added, "We believe that the scene was tampered with as well before the police arrived."

It's interesting ... this comes hours after the D.A. scoffed at the sabotage claim, saying no such evidence has surfaced.

Hannah's lawyer says his client met with Santa Fe County Deputy Sherriff's Tuesday, providing a full interview and continuing to cooperate.

Her legal team says more info keeps coming out that the D.A. needs to investigate, and they want the D.A. and FBI to get to the bottom of what happened with the live rounds they claim ended up in the "dummies" box.

Of course, there's another explanation ... that someone was target practicing during the lunch break and failed to take the live ammo out of the chamber.
