First post, first mini spud gun.

Miniature guns are novelty custom, unique, and sometime downright crude! Common construction materials often include pill bottles or pens. Show us your work!

Yes.

The combustion gases will reach a couple thousand degrees but that temperature lasts for less than one second, even in a closed chamber. The chamber itself (and any epoxy) will only warm up by several degrees since the mass of the plastic (and epoxy) is much much much greater than the mass of the combustion gases.
