Hello all, recently picked up a Del-ton echo for cheap, but I'm not digging the tubular handguard. So I'm stuck with just buying a complete upper and swapping out, or should I tear it down and add what I want. I know keeping the factory would be better, but so much easier to my complete. And ideas and advice would be great. Also, I'm gunlover and paramedic, and my main hobby seems to be always working.
