The 98ci uses the same tank valve thread as every other size in the Alpha Air line, so HK Army's Standard, MP5, HP8, and Turbine Pro regulators fit directly, as do regulators from Ninja, Immortal Air, and Empire.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"so-tab\"\u003e\n\u003cinput id=\"faq-aa98-3\" type=\"checkbox\" name=\"faq-aa98\"\u003e \u003clabel for=\"faq-aa98-3\"\u003eWho should choose the 98ci over the 88ci?\u003c\/label\u003e\n\u003cdiv class=\"so-tab-content\"\u003e\n\u003cp\u003eIf you're already considering the 88ci, the 98ci is worth a look when you want to go a full scenario day, extended op, or several points in a row without swapping tanks. The tradeoff is a bit more length and weight; if that's not a priority, the 88ci or 77ci will feel more compact on your marker.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"so-tab\"\u003e\n\u003cinput id=\"faq-aa98-4\" type=\"checkbox\" name=\"faq-aa98\"\u003e \u003clabel for=\"faq-aa98-4\"\u003eHow much more air does the 98ci hold than the 88ci?\u003c\/label\u003e\n\u003cdiv class=\"so-tab-content\"\u003e\n\u003cp\u003eThe 98ci holds about 11% more air than the 88ci, adding roughly 0.35in of length and about 2.7oz of weight — the smallest jump between any two sizes in the lineup, since it's the last step up to the largest bottle.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"so-tab\"\u003e\n\u003cinput id=\"faq-aa98-5\" type=\"checkbox\" name=\"faq-aa98\"\u003e \u003clabel for=\"faq-aa98-5\"\u003eWill my tank cover fit the 98ci?\u003c\/label\u003e\n\u003cdiv class=\"so-tab-content\"\u003e\n\u003cp\u003eThe 98ci keeps the same 4.4in diameter as every other Alpha Air bottle, so covers sized for that diameter will still fit around it.
