300 BLK build progress, almost there but still need to tweek a couple things. I just installed this Apex hand guard and, while nice, isn't quite right for what I'm looking for.. It's just a hair too long to access the suppressor mount (I know, measure twice right?). So, I have a slightly shorter KA URX 4 inbound next week.. We'll see how that goes.
Nice work Shane, I had mine out today and put a couple hundred rounds of subsonic through it, using three different powders, three different bullets and three different primers, all with fantastic results.
