Designed to fit the ubiquitous 10\/22 and the KJ-WORKS KC02 gas blowback airsoft rifle, this conversion kit is a masterclass in precision manufacturing, constructed from a robust combination of high-grade materials.\u003cbr\u003eAt the heart of the SRUNA-22 is a dual-material construction that prioritizes both durability and functionality. The lower receiver is crafted from PA66 polymer, a material known for its strength and resilience. It features the distinct \"SR-BUP-22\" engraving, adding a touch of authenticated identity to the build. In contrast, the upper handguard is machined from 6061 CNC aluminum, providing a rigid and stable foundation for optics and accessories. This handguard is topped with a full-length Picatinny rail, while M-Lok slots on both sides and the bottom offer unparalleled modularity for attaching lights, grips, and other tactical gear. The premium build is further highlighted by the \"SRUNA\" marking on the aluminum, emphasizing its origins.\u003cbr\u003eThe kit?s commitment to user comfort is evident in its thoughtful ergonomic additions. It includes a TPU rubber stock pad for a non-slip, comfortable shoulder weld, along with an additional 11mm buttpad riser for customizable length of pull. An EVA foam cheek pad completes the package, ensuring a consistent and comfortable cheek weld for optimal sight alignment.\u003cbr\u003eOne of the most critical engineering achievements of the SRUNA-22 is its rigid chassis system, designed for enhanced accuracy. The kit utilizes an integrated, suspended CNC aluminum upper handguard that securely clamps the 10\/22 receiver and barrel. This connection is reinforced with six-directional adjustment screws, creating an independent sighting system. By isolating the optics and barrel assembly from the lower frame and the trigger linkage, this design ensures that external pressures or movements in the chassis do not affect the rifle's zero, delivering consistent accuracy and ballistic stability shot after shot.\u003cbr\u003eFor those concerned about the legal and handling implications of a bullpup conversion, the SRUNA-22 offers a compelling solution. Installing this kit does not increase the rifle?s length of pull (LOP) but dramatically reduces its overall length (OAL). The standard configuration provides an LOP adjustable from 14.3? to 14.75?. For users requiring a longer reach, the optional buttpad riser extends the LOP further to 15.1?. The overall length of the rifle ranges from a remarkably compact 26.3? to 26.7? with the standard setup, and maxes out at just 27.1? with the additional riser. This compact form factor means the rifle does not require registration as a Short-Barreled Rifle (SBR), offering significant tactical and storage advantages without the associated bureaucratic hurdles.\u003cbr\u003ePerhaps the most praised feature of the SRUNA-22 is its revolutionary trigger linkage system. Unlike traditional bullpup conversions that often result in a spongy, compromised trigger pull due to long connecting bars, SRUNA has engineered a sophisticated dual-link pivot lever system. This design ensures a zero-delay, frictionless trigger pull that faithfully preserves the crisp, definitive feedback of the original 10\/22 trigger. By eliminating the mushy feel commonly associated with bullpup designs, the SRUNA-22 allows shooters to enjoy the benefits of a compact platform without sacrificing the precision and control of a factory trigger.\u003cbr\u003eIn terms of compatibility, the SRUNA-22 is designed to be exceptionally versatile. It is suitable for all variants of the 10\/22, with the sole exception of the Takedown model. The handguard?s inner width is thoughtfully engineered to accommodate suppressors up to 1.299 inches in diameter, allowing for a streamlined, integrated look. Furthermore, its robust design extends perfectly to the airsoft community, providing a premium chassis solution for the KJ-WORKS KC02 Gas Blowback (GBB) airsoft rifle.\u003cbr\u003eThe SRUNA-22 is more than just a chassis kit; it is a complete transformation. By combining rugged materials, a rigid accuracy-enhancing design, customizable ergonomics, and an industry-leading trigger linkage, it delivers a bullpup experience that is as reliable and precise as the legendary platform it was built upon.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\u003ch3\u003e\u003cb\u003eKey Feature\u003c\/b\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePolymer\/ 6061 CNC Aluminum Construction Conversion Kit\u003c\/li\u003e\n\u003cli\u003eBlack Color Version\u003c\/li\u003e\n\u003cli\u003ePA66 Polymer Lower Receiver (Engraved \"SR-BUP-22\" Marking)\u003c\/li\u003e\n\u003cli\u003e6061 CNC Aluminum Upper Handguard (Picatinny Rail on top\/ M Lok on Both \u0026amp; Bottom) (Engraved \"SRUNA\" Marking)\u003c\/li\u003e\n\u003cli\u003eSUS304 Metal Sheet Stamping Trigger Linkage\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan style=\"color: rgb(92, 81, 104); font-family: din-next-w01-light, din-next-w02-light, din-next-w10-light, sans-serif; font-size: 16px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; display: inline !important; float: none;\"\u003eTPU \u003c\/span\u003eRubber Stock Pad\u003c\/li\u003e\n\u003cli\u003eWith an Additional Butt Pad (11mm)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eEVA Cheek Pad\u003c\/li\u003e\n\u003cli\u003eSuitable For 10\/22 all variants ( except the take down version) \u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eHandguard Inner Width: Compatible with suppressors up to 1.299? in diameter\u003c\/li\u003e\n\u003cli\u003eAlso fit for KJ-WORKS KC02 Gas Blow Back GBB Airsoft Rifle\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SRU","offers":[{"title":"Default Title","offer_id":48616152826084,"sku":"SRUNA-22-BK","price":360.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0617\/1325\/2580\/files\/SRUNA-22-BK-1e.jpg?v=1774594799","url":"https:\/\/www.ehobbyasia.com\/products\/sru-sruna-22-bullpup-chassis-kit-for-ruger-10-22-kj-works-kc02","provider":"eHobbyAsia","version":"1.0","type":"link"}
