I recently bought a new URG-I off the EE and was blown away by the precision and quality workmanship that went into this upper. Back when these first came out a few years ago, I had one but only for a short time till (I moved to California for a bit). There have been many good uppers/rifles I have enjoyed over the years, but everything about the upper just has me smitten
.
-The SF4P is perfectly timed with clean P/W job.
-Seems all their parts, even the smallest ones, have detailed installation and usage instructions present.
-NSN markings on SF4P, Rail, and CH (I'm a nerd like that).
-The machining of everything (especially the REBCG) is as good as it gets.
-"G" marking on the upper and the markings on the bolt are easy to ready and sharp. When a lot of companies don't go through the MPI/HPT testing and/or do not mark as such, it is refreshing to see this.
-Buying this upper at full price is a square deal to me, but when they are on sale it is a steal IMO.
-The improvements they made to the BCG are well thought out. Will I ever shoot enough to notice them, no.
-Hammer forged barrel with a slightly modified GOV profile is good for me.
-Lastly, the gas block install is the most solid (or at least as solid as anything else out there) mounting.
Thanks for listening!!
