So I'm planning to SBR one of my 15-22 lowers but can't decide if I should do the original gen 1 or the new gen 2 sport. Hard to see if any changes were made between the two but I do see that the gen 1 has a more clean finish on the polymer vs the gen 2 which is rougher.
Anyone know if the gen 2 has any additional, positive changes that make it worth SBRing over the gen 1? I know uppers are interchangeable and can't really see the difference.
