{"product_id":"ar15-h3-buffer","title":"AR15 H3 Buffer","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eCarbine length (3.25″) | Raw finish | ~5.15 oz complete\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThis isn't your average H3. This two-piece design uses a full solid-steel rear weight to dead-blow the bolt carrier, killing bolt bounce in full-auto and rapid-reset-trigger setups. The result is cleaner, more consistent function when you need it most.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe dead-blow action depends on a 1\/16″–1\/8″ gap between the head piece and the body. We set this gap at the factory, but it's fully adjustable if your build calls for it.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eWe've run these through a wide range of AR configurations — barrels as short as 7″ — and they perform flawlessly. Paired with a rapid-reset trigger, 5.1–5.2 oz is the sweet spot that really makes an FRT sing.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eWhy the steel weight matters\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe sliding portion weighs 4.3 oz — the same as the tungsten weights in a conventional H3 — but it's machined from 8620 steel instead of tungsten, which significantly cuts manufacturing cost without giving up performance.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eBe aware: there are other so-called \"H3\" buffers out there that don't disclose the weight of their sliding portion — and there's a reason for that. That sliding weight is far too light to actually prevent bolt bounce. Weight is the whole point.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003e⚠️ IMPORTANT — READ BEFORE ADJUSTING\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eYou \u003cstrong\u003eMUST\u003c\/strong\u003e loosen the small locking set screw on the side of the buffer body \u003cstrong\u003ebefore\u003c\/strong\u003e turning the main head screw.
