Westside Sizzurp Smar do broni

Used it during a long range session with heavy semi-auto fire, and the action stayed slick the whole time even as the barrel got seriously hot. No reapplication needed mid-day, which is exactly what I was hoping for.

Broke in a new rifle this weekend and ran a couple hundred rounds through it—the bolt stayed buttery smooth the whole time, and that high-temp protection held up even when the barrel got seriously hot. This stuff doesn't burn off like the last lube I tried.

Broke in a new bolt carrier and this stuff stayed put through a full mag dump at the range — no smoke, no mess, just smooth cycling the whole time. The high-temp formula holds up way better than the cheap stuff I was using before.
