Looking for 20in styainless fluted upper, not a full bull though. front gas block with a rail so can mount a flip front sight and use throw lever rings on the flat top. anyone recommend a good manf ? Would like to stay < $600
I was looking at RRA uppers, but I dont want a bull barrel upper, and all the other uppers have the standard A2 front sight block.
[edited to add]
actually I kinda like the RRA A4 upper in stainless, maybe I can just replace the front sight block ?
