So I just discovered Freedom15 - ar15mold.com through their youtube channel and it seems relatively easy to pour your own resin lower with this kit. The base mold and resin kit costs $319 and includes enough resin to produce 5 lowers. $65.99 per lower. (not bad) Curious if anyone has tried this yet. Also wanted to put it out there and see if anyone would be interested in trying this with me. Cheers.
