JSE is located just outside of town by me. We stumbled across them just a few weeks ago. After a few trips to the shop, I felt like not only did they know their sh1t, but they are actually darn nice people too.
I'm doing my first build and am using a DTI 16" 5.56 upper with MI gen2 ff hand guard from them.
They had tons of stuff in house with brands from DPMS to RRA to Daniel to Noveske.
I'd give them a try if you see something you like. Also call them if something's listed as out of stock. They seem pretty busy and might be a few days behind on new stock listed.
