The parts machined from aircraft-grade aluminum are top-notch both aesthetically and structurally.

After extensive research, Retro Arms developed several innovative features: A split collar nut is used to stabilize and secure the inner barrel, centering it very tightly within the hop-up chamber body. During tightening, there is no need to apply excessive force. This part is, of course, also machined from aluminum. Although the chamber is designed especially for Retro Arms CNC gearboxes, it can be installed in almost any V3 gearbox. In some cases, the front screw mount may need to be filed thinner. Additionally, the hop-up chamber can be fitted with Retro Arms’ separate hop-up spacer, which prevents incorrect magazine seating in the magwell and improves the chamber’s alignment in the receiver.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCompatible nozzle: 20.1mm\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cstrong\u003ePackage Includes\u003c\/strong\u003e:\u003c\/p\u003e\n\u003cp\u003e1 pc Hop-Up chamber for AK series (anodized, material aircraft aluminum EN AW 7075)\u003cbr\u003e\n1 pc Setting lever (anodized, material aircraft aluminum EN AW 7075)\u003cbr\u003e\n1 pc Pushing lever with cut for common spacers (anodized, material aircraft aluminum EN AW 7075)\u003cbr\u003e\n2 pcs machine screw M2.5 x 3mm (Steel, 12050)\u003cbr\u003e\n1 pc machine screw M3 x 12 mm (steel 8.8 strength)\u003cbr\u003e\n1 pc C-Clip AK (ABS plastic)\u003cbr\u003e\n1 pc sliding pin (ABS plastic)\u003cbr\u003e\n1 pc O-ring (vulcanized rubber)\u003cbr\u003e\n1 pc split collar nut (anodized, material aircraft aluminum EN AW 7075)\u003c\/p\u003e\n\u003cp\u003eThe chamber is delivered unassembled!\u003c\/p\u003e\n\u003cdiv class=\"shop-loop-head\"\u003e\n\u003cdiv class=\"woodmart-woo-breadcrumbs\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Retro Arms","offers":[{"title":"Default Title","offer_id":54236604432732,"sku":"6564","price":37.9,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0612\/6636\/2610\/files\/2669_0031-05095_1749.jpg?v=1743364589"},{"product_id":"retro-arms-cnc-machined-m4-basic-hop-up-chamber","title":"Retro Arms CNC-machined M4 BASIC hop-up chamber","description":"\u003cp\u003eRetroArms CNC-machined M4 BASIC hop-up chamber is an upgrade part for AR-15\/M4-type AEG airsoft guns that improves accuracy and reliability.

The lower the rating, the softer the rubber. Different hardness levels perform differently across various power ranges. In other words, the hardness rating can be used as a guideline when selecting the right rubber for your airsoft gun, based on its power. As a rule of thumb, the more powerful the gun, the harder the hop-up rubber should be.
