I chose a Gemtech Sandstorm 30 cal 5/8-24, titanium body like this one:

That is not mine but it's the same model. (down the page a bit)
It's still waiting on ATF approval. I chose it for the low weight and it's ability to fit and handle several of my rifles including AAC 300 BLK Rem 700 and AR-15, an AAC 260 Rem 700, and 243 Win and 308 Win DPMS LR-()s. Part of my choice was from web searches on performance and part because I have a local dealer.
