Best bolt knob I've used!

Posted by McCall on Jan 27th 2026

This port knob appears to be either 3-D printed or cast. I was initially concerned about the durability with it because it is so light. I've had it for a few months now and I'm not particularly gentle on my gear as I use this rifle for competitions like the sniper adventure challenge and mammoth. In the past, I have really liked aggressive Bol knobs to make sure that I get a good purchase on them but the way this one functions, although smooth, actually helps me cycle the rifle faster. definitely worth it!
