Expert Verdict Reviewed by the SuperArbor Pro Desk

The 6:1 thrust ratio is the sweet spot for latex, acrylic and silicone cartridges; step up to a higher-ratio gun for high-viscosity or bulk materials. The ratchet rod is forgiving for occasional users, and the built-in seal puncture tool and spout cutter save fumbling for a knife on the job. The welded backcap and heat-treated friction plate hold cartridges securely in the half-barrel cradle.

Keep fingers clear of the spout cutter and seal puncture tool; both have sharp edges and cut points.
