Hey guys - an update on some gas blocks. We've had some issues with gas blocks coming out wrong. It's really cut down our supply for now. I will have more coming in on April 10th, and will then be able to have a batch of 50 or so upgrade blocks ready to ship. I wish I could get them to you sooner, but unfortunately the blocks we have left are pre-designated to orders before yours. It won't be long, though. Just a few weeks. Thankfully nobody has been waiting TOO long. thanks for your patience, guys.
