The factory part copes with the gun as standard and starts to matter the moment the spring rates go up, because a harder recoil spring and a stiffer hammer spring both end up loading the same component.\u003c\/p\u003e\u003cp\u003eMachining it from steel is the fix. It holds its sear engagement surfaces rather than peening them over, which is what keeps the trigger feeling the same in month six as it did in week one.\u003c\/p\u003e\u003cp\u003eIt is listed for the AAP-01 and the Marui EU18, so it spans both platforms. They carry no description for it, and Action Army publish a parts list rather than a datasheet, so the fitment and the material are what is stated and that is all we will claim.\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;\"\u003eFitment\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eAction Army AAP-01 and Tokyo Marui EU18\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\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;\"\u003eSteel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eConstruction\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eCNC machined\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eFunction\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eReplacement hammer\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\u003eThis is an internal part. Fitting it means stripping the lower, so give yourself bench time and somewhere to lose the small components.\u003c\/p\u003e\u003cp\u003eIt is a durability upgrade before it is a performance one. If the gun is standard and working, you are buying longevity rather than a change you will feel on the first magazine.\u003c\/p\u003e\u003cp\u003eWorth doing at the same time as any spring change, because the lower has to come apart for both.\u003c\/p\u003e\u003cp\u003eThere is no published figure for the hammer. Action Army put out an exploded diagram of the part and nothing numeric alongside it.\u003c\/p\u003e\u003ch2 style=\"font-size:16px;color:#1B3A6B;margin:18px 0 8px;\"\u003eFrequently asked questions\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eWhat does a steel hammer actually improve?\u003c\/strong\u003e\u003cbr\u003eIt keeps its shape. The sear surfaces stay crisp under repeated hard strikes instead of gradually deforming, so the trigger behaves the same over time.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill I notice it immediately?\u003c\/strong\u003e\u003cbr\u003eProbably not. It is a wear part upgrade, so the benefit shows up over months rather than in the first game.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes it fit the Marui EU18?\u003c\/strong\u003e\u003cbr\u003eYes — both the AAP-01 and the Marui EU18 are listed.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs it hard to fit?\u003c\/strong\u003e\u003cbr\u003eIt sits inside the frame, so the lower is coming apart either way. Manageable with one AAP strip-down behind you, slow the first time.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does it weigh?\u003c\/strong\u003e\u003cbr\u003eNo figure exists for it publicly. Steel is heavier than the part it replaces, and that is as far as the sources go.\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 Do it in the same strip-down as a spring or trigger change rather than opening the gun twice.
