[154 chars]\n\n     SELLER FACTS (from submission #36700-24, as given): Category Gel Blaster - Rifle. Brand + Model\n     entered as \"GBBR Colt m4\" - confirmed against the seller's own purchase receipt (screenshot supplied)\n     as WM Colt M4 with DD Mk18 Handguard MWS(ZET System) GBBR Gel Blaster. Condition: Like New. Upgrades\n     fitted: Sig Romeo5 1x20 Compact red dot, MOE Stubby foregrip (both on the receipt). Known faults: None.\n     Description (seller's own words): \"Brought it brand new, fired it only a few times and then it has\n     lived in the carry case. Needs a home where it will actually be used.\" Auto-accept: $1,000. Asking:\n     $1,250. Pickup or shipping: Both. Included: magazine(s) - count not specified on form - and\n     extras\/spares - not itemised on form. Seller: Margate QLD 4019 (confirmed via postcode\/street lookup,\n     NOT stated in listing body per no-personal-details rule). Contact details on file, not published.\n\n     PRICE CHECK (against seller's own receipt + live retail, 14 August 2026):\n     - Base blaster new: $1,550 (receipt) - confirmed CURRENT and IDENTICAL live price at x-forcetactical.com.au,\n       currently OUT OF STOCK there - genuine current-market data point, not assumed.\n     - Extra WM MWS mag MK3.0: $200 (receipt)\n     - Sig Romeo5 red dot: $120 (receipt)\n     - MOE stubby foregrip: $15 (receipt)\n     Buy-new-equivalent for this exact build: $1,885. Asking $1,250 = 66% of that - lands right in the\n     60-70% \"lightly used, good condition\" band from the pricing convention. Auto-accept $1,000 = 53% -\n     seller's floor, not touched. Pricing looks fair, no flag needed on the numbers.\n\n     FLAG FOR PATRICK: \"extras\/spares included\" wasn't itemised on the form - written generically below\n     (\"a spare magazine and a few extras\") rather than guessing what's in the bag. Confirm with Toby exactly\n     what's included (mag count, spares) before this goes live, then tighten the copy if needed.\n     ============================================================ --\u003e\n\u003cdiv style=\"background: #0d0d0d; border: 1px solid #ff0000; border-radius: 12px; padding: 18px 22px; margin: 0 0 24px;\"\u003e\n\u003cp style=\"margin: 0; color: #ffffff; font-size: 16px; line-height: 1.7;\"\u003e\u003cstrong style=\"color: #ff0000;\"\u003eQuick Answer:\u003c\/strong\u003e A like-new WM Colt M4 with a Daniel Defense MK18 handguard, running the MWS (ZET System) gas blowback platform — barely fired, kept in its carry case since new.

The seller bought it brand new, fired it a handful of times, then it sat in the carry case — so you're buying a blaster in as-new condition without paying the new-in-box price.

That's not a coincidence for MWS (ZET System) GBBRs generally: gas blowback builds sell out faster than they get restocked because they're a step up from a standard electric build and there simply aren't that many made. When the new stock dries up, a barely-used private listing like this one is often the only realistic way to get the platform without going on a waitlist and hoping. Buying private through a managed marketplace closes the gap that usually makes people nervous about second-hand GBBRs — you get the platform now, at a fair price, with the payment held until you're happy.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"background: #0d0d0d; border: 1px solid #ff0000; border-radius: 12px; padding: 18px 22px; margin: 24px 0;\"\u003e\n\u003cp style=\"margin: 0 0 8px; color: #ff0000; font-weight: 800; font-size: 18px;\"\u003ePickup Margate, 4019, QLD or shipped QLD-wide\u003c\/p\u003e\n\u003cp style=\"margin: 0; color: #ffffff; line-height: 1.7;\"\u003eCollect in person from Margate, 4019, QLD, or have it shipped tracked anywhere in Queensland with postage included in the price.
