It's a deliberately conventional shape, and that's the point. Standard quad rail mounting means every grip, light, laser, and sight that fits a 20mm RIS will sit on this rifle without an adapter.\u003c\/p\u003e\n\u003cp\u003eUnderneath the polymer furniture is the same Gen2 reinforced V2 gearbox running through the entire Pioneer line: 18:1 steel gears, 8mm bearings, a high-torque long-shaft motor, and the M90 quick-change spring system that lets you swap springs without splitting the gearbox. The rotary hop unit and 50° rubber give consistent backspin across the typical UK skirmish BB weight range.\u003c\/p\u003e\n\u003cp\u003eAt 724mm overall the M4SD is the sweet spot of the range — long enough to feel like a proper field rifle, short enough not to snag on doorways or thick woodland cover. The Small Tamiya connector and 9.6v NiMH recommendation keep it skirmish-ready out of the box with no rewiring needed before your first game day.\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;\"\u003ePowered By\u003c\/td\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eElectric\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eCalibre\u003c\/td\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e6mm BB\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background:#f5f5f5;\"\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eMuzzle Energy\u003c\/td\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e1J (~330 FPS with 0.20g)\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eFire Modes\u003c\/td\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eSafe \/ Semi \/ Full-Auto\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background:#f5f5f5;\"\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eInner Barrel\u003c\/td\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e6.03mm precision\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eBarrel Thread\u003c\/td\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e14mm CCW\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background:#f5f5f5;\"\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eHop-Up\u003c\/td\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eRotary, 50° hop rubber\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eGearbox\u003c\/td\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eReinforced V2, Gen2 internals\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background:#f5f5f5;\"\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eGears\u003c\/td\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e18:1 steel, 8mm ball bearings\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eMotor\u003c\/td\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eHigh-torque long-shaft (21,000 RPM)\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background:#f5f5f5;\"\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eSpring\u003c\/td\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eM90, quick-change\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eReceivers \/ Handguard\u003c\/td\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eNylon fibre polymer\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background:#f5f5f5;\"\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eInternals\u003c\/td\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eSteel cylinder head, metal outer barrel, charging handle, bolt catch\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eMagazine\u003c\/td\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e120R mid-cap supplied; M4\/AR-15 AEG compatible\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background:#f5f5f5;\"\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eBattery Connector\u003c\/td\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eSmall Tamiya\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eRecommended Battery\u003c\/td\u003e\n    \u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e9.6v NiMH\u003c\/td\u003e\n  \u003c\/tr\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cstrong\u003eUKARA:\u003c\/strong\u003e As a realistic imitation firearm, this product requires UKARA registration or a valid defence.
