Anything Mega is pretty scarce these days. I’ll keep my eyes open for a rail. Are you needing the standard free float type or the proprietary “Megalithic” type?
I immediately jumped on a couple of the forged AR15 uppers. I haven’t seen those in stock anywhere in probably a year or more.
I need the proprietary one unfortunately. Appreciate you keeping an eye out for one! Awesome rifle. it's a shame they closed shop, good quality stuff!
