I have not seen a RRA upper, but have heard their feed ramps look hacked(dremelled) sometimes. Any info or feed back would be great. Thnx.

They just break the edge where the barrel extension meets the receiver. Very professionally done, no problems on any that I own, have seen, or used.

Cheers,

Props

the ones i had looked like crap.



if you ever need to replace one or the other you are pretty much scewed and forced into destroying either to mate them up. nothing professional about it professional is factory feedramps that are machined properly.

They're a mixed lot, probably because backyard hacks try to copy RRA and sell their hacks off as RRA. These "extended ramps" add absolutely nothing to the function of a properly setup rifle and only come into play if you are shooting nonstandard ammo, like power point type hunting ammo, so it's no wonder why you get claims of perfect function with them. The rifle would function perfectly without them.
