DIY Polymer lowers. Interesting...

[68Charger]

I can see this process being useful for making other things, but forged 7075 lowers (80% or 100%) aren't expensive enough for this to make any sense- but to each their own. There's not even a significant weight savings- they use 6oz of resin- so even considering some doesn't go in, some becomes casting flash, etc... maybe 5.7Oz compared to 8.7Oz for a forged 7075 stripped lower

The process itself is interesting- i checked out their youtube videos...
I assume they're CNC milling cutting board material to make the mold, and I'd be curious about the tensile strength of the resin- properties could probably be improved with the addition of other materials, but then it probably wouldn't pour anymore (and would require injection molding)
