You wind the wheel, you get a few hundred rounds without touching a pouch, and you accept the rattle and the winding in exchange for not reloading. For anyone running a support role or a long defensive position, that trade is usually worth making.\u003c\/p\u003e\n\u003cp\u003eThe steel shell is the part that matters over a season. A polymer magazine lip spreads slightly every time it is seated hard into a magwell, and once it does the magazine starts sitting low and feeding badly. Steel takes that abuse without changing shape, which is why steel hi-caps tend to outlast the gun they were bought for.\u003c\/p\u003e\n\u003cp\u003eIt is a standard M4 and M16 fit, so it drops into the AR-15 pattern AEGs most people already own rather than needing a particular brand of receiver.\u003c\/p\u003e\n\u003ch2 style=\"font-size:16px;color:#1B3A6B;margin:18px 0 8px;\"\u003eSpecifications\u003c\/h2\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;font-size:13px;margin:0 0 18px;\"\u003e\n\u003ctr style=\"background:#1B3A6B;color:#fff;\"\u003e\n\u003cth style=\"padding:7px 12px;text-align:left;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:7px 12px;text-align:left;\"\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003ePlatform\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eM4 \/ M16, AR-15 pattern AEG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eType\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eHi-cap, winding\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eCapacity\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e320 rounds\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eShell material\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eSteel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eFinish\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eBrand\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eCYMA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch2 style=\"font-size:16px;color:#1B3A6B;margin:18px 0 8px;\"\u003eLooking after it\u003c\/h2\u003e\n\u003cp\u003eCYMA give three instructions with this magazine and they are worth following, because a neglected hi-cap jams and a maintained one does not. Oil it with silicone oil before you use it for the first time. Keep oiling it from time to time. And when you put it away, put it away empty.\u003c\/p\u003e\n\u003ch2 style=\"font-size:16px;color:#1B3A6B;margin:18px 0 8px;\"\u003eFrequently asked questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eHow many rounds does it actually hold?\u003c\/strong\u003e CYMA rate it at 320. As with any hi-cap, treat the rated figure as the ceiling rather than a daily target, and it will feed more reliably.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill it fit my M4?\u003c\/strong\u003e It is built to the standard M4 and M16 magazine well, so AR-15 pattern AEGs are the intended fit. If your gun uses a proprietary magwell, check before buying several.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy choose steel over polymer?\u003c\/strong\u003e The shell keeps its shape. Polymer feed lips can spread with hard seating, and a magazine that sits low stops feeding cleanly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShould I store it loaded?\u003c\/strong\u003e No. CYMA specifically say to store it empty, which also takes the tension off the feed spring between games.\u003c\/p\u003e\n\u003cdiv style=\"background:#fffbe6;border-left:4px solid #f0d060;padding:12px 16px;border-radius:0 6px 6px 0;margin:0 0 16px;font-size:13px;\"\u003e\n⚠ \u003cstrong\u003eOil it before first use.\u003c\/strong\u003e This is not optional advice from us, it is CYMA's own instruction. A dry hi-cap feed wheel is the most common reason one of these stops working, and a drop of silicone oil before the first game prevents it.\n\u003c\/div\u003e\n\u003cdiv style=\"background:#1B3A6B;color:#fff;padding:12px 16px;border-radius:6px;margin:18px 0 0;font-size:13px;\"\u003e\n\u003cstrong style=\"color:#fff;\"\u003e💡 Titan Forge Airsoft tip:\u003c\/strong\u003e Buying one magazine tells you whether it feeds in your gun; buying six before you have tested one is how people end up with a drawer of magazines that do not.
