DynaCap Initial Release (2025-11-24)

Thus far, we’ve identified 3 concrete issues.

ISSUE 1: 2u binding due to non-flat wire.
Tolerances are tight to keep wobble down, and the 2u parts are no exception. With tight tolerances, microscopic abnormalities can cause unforeseen issues. Some users reported left-side binding on their 2u assemblies. After reviewing reports, videos, and testing many parts ourselves, we feel confident we’ve found the root cause—actually two compounding issues. On all 2u housings from this run, you may notice two small parting-line marks on the inside left wall. They’re barely noticeable, but at the right angle with the right amount of friction, the slider can bind against them. With a straight wire and proper lube it’s unnoticeable, but with a slightly bent wire the binding can be reproduced. This doesn’t affect all parts and only occurs with a “perfect storm” of tolerances working against each other.

To address this yourself: apply a medium amount of lube to the side wall of the 2u slider (not the housing). Even on the most problematic parts, this resolved the issue during testing. Light lube on the housing corners won’t guarantee a fix, but a visible coat of 205g0 on the slider sides should.

What we’re doing next run: The factory confirmed these two marks can be polished out of the mold. They’ve already begun polishing both internal walls of the 2u housing and the sliding surfaces of the 2u slider. This may slightly reduce scratch, but should remove anything the slider could catch on. To keep 1u and 2u feel consistent, we’ve also asked them to similarly polish the 1u slider mold. More on that once testing is complete.

ISSUE 2: 2u binding due to inner barrel mark.
Some users reported injection-mark issues inside the 2u barrel—confusing since the gate is on the outer wall. After several reports with matching photos, we learned one mold cavity was dented mid-run, and the issue wasn’t caught until production ended. The mold is now fixed, but some affected parts shipped.

To address this yourself: you can safely file away the small nub on the inner barrel. If you don’t see it, your part isn’t affected.

What we’re doing next run: The factory should never have shipped those parts. We’ve asked for more frequent QC checks and isolation of affected parts when mold issues occur. They knew to fix the mold, so they should have known to flag this. That’s unacceptable. We’ve also requested additional polishing of the inner barrel on both 1u and 2u housings—not strictly necessary, but it adds peace of mind.

ISSUE 3: 1u binding due to inner barrel mark.
The same mold-cavity issue occurred on one 1u cavity near the end of the run. This is the rarest issue, but if you experience it, follow the solution and corrective plan listed under ISSUE 2.
