Hi folks, As the title says, I'm putting together my first AR build, mainly from PSA parts. This will be my first AR, and actually my first center fire rifle. As my first and only (for now), it will be a "jack of all trades" of sorts. But realistically it will mostly be for plinking. Our club does have a rifle range that goes out to 220 yards so it will see some proper target shooting, but no competitions or anything. If I ever get into 3-gun, etc., this will be the rifle I start with. NYS's (un)SAFE act has made AR's a bit useless for HD, but it could serve there in a pinch as well if necessary. I'm looking hard at these two uppers, and am torn between them: https://palmettostatearmory.com/psa...er-with-bcg-ch-mbus-sight-set-5165447592.html https://palmettostatearmory.com/psa...lok-upper-with-nib-bcg-ch-mbus-sight-set.html I think I'd really prefer the nitride barrel coating in the first, but I also like the NiB bolt carrier that come with the second. And I'm thinking perhaps the pencil barrel on the 2nd might be preferable as well, but are those benefits worth the "downgrade" of the stainless barrel? As I understand it, stainless *should* be a bit more accurate for slow target shooting, but groups will open up more quickly as the barrel heats up (particularly since this one is a pencil profile), and tends to wear out faster (not that I'll likely be wearing either one out any time soon). I can't shake the thought that the Nitride coating would be the preferred finish, and am thinking perhaps it would be simpler and cheaper to drop in a nicer bolt carrier later than to change out the barrel. Anyway, just curious what people think of these 2 options. Thanks very much!!
