Compounding the problem is that the opening into the chamber for contact is a circle, breaking many conventions in airsoft hop up chamber design.\u003cbr\u003e\u003cbr\u003eSo we designed this little doohicky to solve that! In the package will be two different nubs.\u003cbr\u003e\u003cbr\u003eThe first of which provides a curved surface to press against the BB whilst it’s in the chamber, and provides an even distribution of force over it from the TDC screw.\u003c\/p\u003e\n\u003cp data-rte-preserve-empty=\"true\"\u003eThe second one is a bit smaller and has an arch designed to match around the 4uantum Friction Pro Nub (not included) which will also work with others such as the Omega Nub (not included) or a normal tubular bucking.\u003c\/p\u003e\n\u003cp data-rte-preserve-empty=\"true\"\u003eIn addition, both versions have an arm that prevents the pieces from rotating and falling out of alignment by indexing against the convenient slot in the top of the chamber\u003c\/p\u003e\n\u003ch3 data-rte-preserve-empty=\"true\"\u003eUpdate\u003c\/h3\u003e\n\u003cp data-rte-preserve-empty=\"true\"\u003eNow shipping a flexible Nylon resin version, this material should be tougher and more resilient to impact as it has a slight flex to it.\u003c\/p\u003e\n\u003cp data-rte-preserve-empty=\"true\"\u003e\u003cbr class=\"ProseMirror-trailingBreak\"\u003e\u003c\/p\u003e\n\u003ch2 data-rte-preserve-empty=\"true\"\u003e\u003cstrong\u003eIMPORTANT NOTE:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp data-rte-preserve-empty=\"true\"\u003eIf you opt to use the 3rd party nub holding version, there may be cases where you will need to file down the end of the TDC screw so that it can get deep enough to engage with the indexing nub (The clicky thing).
