I noticed some of these braces are on backorder now so who here is in the process of doing a build, and if so which upper are you using?

Ordered yesterday (Adams 7.5" PDW EVO UPPER):

I've been unable to decide which upper I want for a shorty, and I think you just helped me out! I have a 11.5" AA Tactical Evo upper and it is just awesome. Would be nice to have a second AA around. Great quality stuff, especially for the money.

I'm just using the SBX brace right  now. I like the feel of the SBX just fine but it doesn't look that good. I just ordered the Phase 5 Hex 2 buffer tube and a SB-15 brace to match it. That should look at lot cooler. A plain setup with SBX on the lower just doesn't do justice to the AA upper.

Did a pistol a while back used a 10-5 in upper from Hardenedarms.com Very happy with it!
