Anodising wears, threads pick up damage from a cross-threaded cylinder head, and a dented cylinder will not seal however good the o-rings are.\u003c\/p\u003e\n\u003cp\u003eBuying the cylinder on its own is a great deal cheaper than replacing a whole engine, and it is a job most people can do at the bench with the o-ring kit and an hour. If the engine itself still holds pressure, the cylinder is usually the only part that needs to change.\u003c\/p\u003e\n\u003cp\u003eThis is the genuine Wolverine part, not a generic VSR cylinder. The internal diameter and the thread form are specific to the BOLT M assembly — a standard sniper cylinder will not accept the engine.\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;\"\u003eFits\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eWolverine BOLT M HPA engine\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eSold as\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eCylinder only — no engine, head or o-rings\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eMaterial\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eAnodised aluminium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\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\n\u003ch2 style=\"font-size:16px;color:#1B3A6B;margin:18px 0 8px;\"\u003eFrequently asked questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eWill this fit the standard BOLT?\u003c\/strong\u003e No. The BOLT and BOLT M are different assemblies.

The BOLT M kit is a separate item and costs very little against the risk of a slow leak.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I reuse my existing cylinder head?\u003c\/strong\u003e If the head is undamaged and the threads are clean, yes. Check the sealing face for scoring before you rebuild.\u003c\/p\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 A cylinder that will not hold pressure is usually a seal, not the cylinder — strip it and check the o-rings before you buy.
