That retention is the spring’s job, and when it tires the symptom is not a dead rifle but an inconsistent one — the odd dry cycle, or rounds going missing between the magazine and the chamber.\u003c\/p\u003e\u003cp\u003eIt is a thin piece of wire under constant light load, which is exactly the sort of component that fatigues slowly rather than breaking cleanly. People chase magazines and buckings for months before looking at it.\u003c\/p\u003e\u003cp\u003eThis is the Wolverine part for the Gen 3 tube. It is cheap enough that replacing it on suspicion is a reasonable diagnostic step while the upper is already open.\u003c\/p\u003e\u003ch2 style=\"font-size:16px;color:#1B3A6B;margin:18px 0 8px;\"\u003eSpecifications\u003c\/h2\u003e\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;\"\u003ePart\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eBB retention spring for the Gen 3 feed tube\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\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;\"\u003eWolverine MTW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eFeed tube generation\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eGen 3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eSupplied as\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eSpring only\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eManufacturer\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eWolverine Airsoft\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2 style=\"font-size:16px;color:#1B3A6B;margin:18px 0 8px;\"\u003eGood to know before you buy\u003c\/h2\u003e\u003cp\u003eConfirm your feed tube generation first.

Getting to it means opening the upper, so pair the job with a bucking change or a hop service instead of doing it on its own.\u003c\/p\u003e\u003ch2 style=\"font-size:16px;color:#1B3A6B;margin:18px 0 8px;\"\u003eFrequently asked questions\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eWhat goes wrong when this wears?\u003c\/strong\u003e\u003cbr\u003eRetention gets weaker, so BBs can creep back down the tube.

This is the spring by itself; the feed tube is listed separately.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill it suit an older MTW?\u003c\/strong\u003e\u003cbr\u003eIt is the Gen 3 part. Earlier tubes are built differently, so tell us your rifle and we will confirm which one you need.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this the same as the hop spring?\u003c\/strong\u003e\u003cbr\u003eNo. The hop spring sits in the hop unit and sets pressure on the bucking; this one works in the feed path and holds BBs ready.\u003c\/p\u003e\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 Replace it at the same time as the retention screw if you have the tube out — both are pennies and both mean opening the upper again if you skip one.
