Dye UL-I Tip 14", gold polished

The UL-I back by Dye impresses with high-quality, a ultra lightweight construction and the use of Dye UL-I resp. Planet Eclipse PWR Inserts.

UL-I stands for "Ultralight-Inserts" and it is the first barrel by Dye, which uses an insert system. But not all inserts are the same and that's why Dye uses the brilliant PWR insert system from Planet Eclipse.

The UL-I inserts are utilizing the same technology as the PWR inserts and are compatible with Dye's UL-I and Planet Eclipse's S63 barrel system.

Unlike commercial cases, UL-I inserts are flush against the firing chamber (of the marker breech), eliminating any stepping. Tolerances or interference factors during firing are virtually non-existent, resulting in a high level of efficiency and accuracy.
