FLUXED HI-FORCE 44™ Reviews & Ratings

BROWNELLS FLUXED HI-FORCE 44™

The Brownells Fluxed Hi-Force 44™ combines the proven strength and performance of Hi-Force 44™ silver-bearing solder with a built-in flux core, creating a convenient all-in-one solution for firearm assembly, repair, and custom gunsmithing projects. By incorporating Brownells' proprietary Blitz flux directly into the solder wire, this product eliminates the need to apply a separate flux during most soldering operations, simplifying setup and reducing cleanup time.

Designed for gunsmiths and firearm enthusiasts, Fluxed Hi-Force 44™ delivers strong, reliable bonds on steel, stainless steel, brass, copper, and other commonly encountered firearm metals. The low flow temperature helps reduce heating time and minimizes the risk of heat damage to surrounding components while still producing durable joints capable of withstanding recoil, vibration, and long-term use.

Ideal for attaching sights, scope bases, sling swivel studs, ribs, and other firearm components, this flux-cored solder offers the convenience of a self-contained soldering solution without sacrificing performance.

Hi Flux

It worked perfectly on a 94 front ramp. I even used it on a Benjamin pellet rifle to hot glue th barrel back on in the front. I hammered it flat and slid it under the barrel, worked like a charm.

Would you recommend this? Yes, I would recommend to a friend

Problem solver

Easier to use than solid core Hi Force, and yields solid joints that are useful for medium stress applications. Won't replace silver braze, obviously, but a nice strong solder.

Definitely not a fan. Horrible flow

Im partially convinced the manufacturer didnt put any flux in mine. This stuff flows horribly. Seems to take way more heat than the specs said (475 degrees). Overall not impressed at all. Horribly expensive for something Ill never find a use for.
