The \r\nlower receiver is crafted from PA66 polymer, a material known for its \r\nstrength and resilience. It features the distinct \"SR-BUP-22\" engraving,\r\n adding a touch of authenticated identity to the build. In contrast, the\r\n upper handguard is machined from 6061 CNC aluminum, providing a rigid \r\nand stable foundation for optics and accessories. This handguard is \r\ntopped with a full-length Picatinny rail, while M-Lok slots on both \r\nsides and the bottom offer unparalleled modularity for attaching lights,\r\n grips, and other tactical gear. The premium build is further \r\nhighlighted by the \"SRUNA\" marking on the aluminum, emphasizing its \r\norigins.\u003cbr\u003eThe kit?s commitment to user comfort is evident in its \r\nthoughtful ergonomic additions. It includes a TPU rubber stock pad for a\r\n non-slip, comfortable shoulder weld, along with an additional 11mm \r\nbuttpad riser for customizable length of pull. An EVA foam cheek pad \r\ncompletes the package, ensuring a consistent and comfortable cheek weld \r\nfor optimal sight alignment.\u003cbr\u003eOne of the most critical engineering \r\nachievements of the SRUNA-22 is its rigid chassis system, designed for \r\nenhanced accuracy. The kit utilizes an integrated, suspended CNC \r\naluminum upper handguard that securely clamps the 10\/22 receiver and \r\nbarrel. This connection is reinforced with six-directional adjustment \r\nscrews, creating an independent sighting system. By isolating the optics\r\n and barrel assembly from the lower frame and the trigger linkage, this \r\ndesign ensures that external pressures or movements in the chassis do \r\nnot affect the rifle's zero, delivering consistent accuracy and \r\nballistic stability shot after shot.\u003cbr\u003eFor those concerned about the \r\nlegal and handling implications of a bullpup conversion, the SRUNA-22 \r\noffers a compelling solution. Installing this kit does not increase the \r\nrifle?s length of pull (LOP) but dramatically reduces its overall length\r\n (OAL). The standard configuration provides an LOP adjustable from 14.3?\r\n to 14.75?. For users requiring a longer reach, the optional buttpad \r\nriser extends the LOP further to 15.1?. The overall length of the rifle \r\nranges from a remarkably compact 26.3? to 26.7? with the standard setup,\r\n and maxes out at just 27.1? with the additional riser. This compact \r\nform factor means the rifle does not require registration as a \r\nShort-Barreled Rifle (SBR), offering significant tactical and storage \r\nadvantages without the associated bureaucratic hurdles.\u003cbr\u003ePerhaps the \r\nmost praised feature of the SRUNA-22 is its revolutionary trigger \r\nlinkage system. Unlike traditional bullpup conversions that often result\r\n in a spongy, compromised trigger pull due to long connecting bars, \r\nSRUNA has engineered a sophisticated dual-link pivot lever system. This \r\ndesign ensures a zero-delay, frictionless trigger pull that faithfully \r\npreserves the crisp, definitive feedback of the original 10\/22 trigger. \r\nBy eliminating the mushy feel commonly associated with bullpup designs, \r\nthe SRUNA-22 allows shooters to enjoy the benefits of a compact platform\r\n without sacrificing the precision and control of a factory trigger.\u003cbr\u003eIn\r\n terms of compatibility, the SRUNA-22 is designed to be exceptionally \r\nversatile. It is suitable for all variants of the 10\/22, with the sole \r\nexception of the Takedown model. The handguard?s inner width is \r\nthoughtfully engineered to accommodate suppressors up to 1.299 inches in\r\n diameter, allowing for a streamlined, integrated look. Furthermore, its\r\n robust design extends perfectly to the airsoft community, providing a \r\npremium chassis solution for the KJ-WORKS KC02 Gas Blowback (GBB) \r\nairsoft rifle.\u003cbr\u003eThe SRUNA-22 is more than just a chassis kit; it is a \r\ncomplete transformation. By combining rugged materials, a rigid \r\naccuracy-enhancing design, customizable ergonomics, and an \r\nindustry-leading trigger linkage, it delivers a bullpup experience that \r\nis 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\u003eOlive Drab 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":48616204697828,"sku":"SRUNA-22-OD","price":376.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0617\/1325\/2580\/files\/SRUNA-22-OD-1e.jpg?v=1774596268","url":"https:\/\/www.ehobbyasia.com\/products\/sru-sruna-22-bullpup-chassis-kit-for-ruger-10-22-kj-works-kc02-od","provider":"eHobbyAsia","version":"1.0","type":"link"}
