The '''CS/LR4 7.62&nbsp;mm High-Precision Sniper Rifle System''' ({{zh|s=CS/LR4 7.62毫米高精度狙击步枪系统|p=Qī diǎn liù'èr Háomǐ Gāo jīngdù jūjī bùqiāng xìtǒng}}),<ref name="gw_cslr4" /> also known as '''NSG-1''',<ref name="mf_nsg1" /> is a [[bolt-action]] [[sniper rifle]] designed and manufactured by Chinese company [[Norinco]]. The rifle features a [[free-floating barrel]] and is chambered in the specifically designed CS/DFL3 ([[7.62×51mm NATO|7.62×51mm]]) high-precision [[firearm cartridge|cartridge]] in a 5-round [[box magazine]], while can also accept other [[.308 Winchester]] ammunition.<ref>{{cite web|url=https://nationalinterest.org/blog/the-buzz/why-chinas-snipers-should-be-feared-26083 |title=Why China's Snipers Should Be Feared |website=National Interest |date=8 June 2018 |first=Charlie |last= Gao}}</ref>
The CS/LR4 is called a "system" because it consists of not only the rifle, but also dedicated [[telescopic sight]]s, specifically designed ammunition, a [[ballistic calculator|ballistic calculation]]/[[rangefinder]] [[binoculars]] and other accessories.<ref name="gw_cslr4" />
==Design and development==
The CS/LR4 is the successor to the [[JS 7.62]]mm sniper rifle, which was designed by Jianshe Industries (Group) Corporation of [[Chongqing]] in 2003. The development of the CS/LR4 started around 2008. The weapon system was adopted by the [[People's Police of the People's Republic of China|Chinese police force]] and [[People's Armed Police]] around 2012. The weapon does not have an official military designation from the [[People's Liberation Army]] and only saw limited use by [[People's Liberation Army Special Operations Forces|special operation force]]s.<ref name="gw_cslr4">{{cite web|url=http://pewpewpew.work/china/sr/cslr4/cslr4.htm |title=CS/LR4狙击步枪 |language=Chinese |website=Guns' World}}</ref>
The CS/LR4 is largely similar to [[5.8×42mm]] [[CS/LR3]] (QBU-141) with an enlarged, [[accurized]] barrel chambered in [[7.62×51mm NATO|7.62×51mm]]. The gun is a manually operated [[bolt-action]] rifle. It features rotary bolt and free-floating barrel. A fixed, thumb-hole style stock is made from polymer, with fully adjustable (top-down and front-rear) buttpad, cheek rest, and integrated monopod. A segment of [[picatinny rail]] is mounted on top of the ejection window, with another segment mounted on top of the barrel for thermal/night vision sight. The picatinny rail is supported by the handguard without touching the barrel, thus maintaining the accuracy provided by the free-floating design. CS/LR4 has a double-stage trigger to facilitate precision shooting, and the pull weight can be customized between 8N and 15N.<ref name="gw_cslr4" /> The accuracy is 1[[Sniper rifle#Accuracy|MOA]] at {{convert|600|m|yd|abbr=on}}.<ref name="mf_nsg1">{{cite web|url=https://modernfirearms.net/en/sniper-rifles/standart-caliber-rifles/china-standart-caliber-rifles/nsg-1-cs-lr4-eng/ |title=NSG-1 / CS-LR4 |website=modernfirearms}}</ref>
The assorted sighting device of the CS/LR4 system includes CS/OS15 (8x-32x) daylight scope, CS/OS20A (4x-15x) daylight scope, and night-vision devices.<ref>{{cite magazine |author=<!--Staff writer(s); no by-line.--> |title=CS/OS19型白光瞄准镜 |url=https://mall.cnki.net/magazine/Article/QBQI201618007.htm |magazine=轻兵器 |location=China |publisher=Qing Bing Qi Publishing |date=2018 |access-date=10 June 2021}}</ref><ref name="cslr4a">{{cite web |url=https://new.qq.com/omn/20210411/20210411A09P0300.html |title=国产LR4高精度狙击步枪亮相委内瑞拉特种部队 更先进型号已经研制成功 |website=Tencent News |date=11 April 2021 |language=Chinese |access-date=10 June 2021 |archive-date=10 June 2021 |archive-url=https://web.archive.org/web/20210610153124/https://new.qq.com/omn/20210411/20210411A09P0300.html |url-status=dead }}</ref>
===CS/LR4A===
[[File:CS-LR4 Sniper Rifle @ PA 122nd Anniversary Caravan.jpg|thumb|CS/LR4A showcased at 122nd Anniversary Caravan of the [[Philippine Army]].]]
CS/LR4A is the improved variant of CS/LR4. The new variant has extended barrel which is approximately {{convert|27|in|mm|abbr=on|1}} long. CS/OS15 (8x-32x) scope is improved with wider field of view (FOV). A new scope with better ergonomics design and lower magnification (4x-15x) called CS/OS20 is also introduced.<ref name="cslr4a" />
===CS/LR35===
{{Main|CS/LR35}}
CS/LR35 is the further development of CS/LR4. CS/LR35 is available in two versions chambered in either [[7.62×51mm NATO]] or [[.338 Lapua Magnum|8.6×70mm Lapua Magnum]]. Improvements include reinforced material for the barrel, lightweight rifle body, fully adjustable folding stock, and CS/DEL3A high precision cartridge in a 5-round [[box magazine]]. The weight is less than {{convert|6|kg|abbr=on}}. The accuracy is claimed to be ≤0.5[[Sniper rifle#Accuracy|MOA]] at {{convert|100|m|yd|abbr=on}}, ≤0.75MOA at {{convert|300|m|yd|abbr=on}}, and ≤1MOA at {{convert|800|m|yd|abbr=on}}.<ref>{{cite web |url=http://cjaie.com/content/details80_3137.html |title=CS/LR35 |website=JING AN |access-date=2021-06-09 |archive-date=2021-06-09 |archive-url=https://web.archive.org/web/20210609204824/http://cjaie.com/content/details80_3137.html |url-status=dead }}</ref>
The 8.6×70mm variant of the rifle can be differentiated by its slightly longer barrel with a handguard that only has four ventilation holes whereas the 7.62 variant has seven smaller ones.<ref name="sina_lr35">{{cite web|url=https://mil.news.sina.com.cn/zhengming/2021-01-07/doc-iiznezxt1012888.shtml |title=轻武器迎来大爆发 解放军又装备两款新型高精狙(图) |language=Chinese |website=Sina News |date=7 January 2021}}</ref> The manufacturer claims that, with 8.6×70mm ammunition, the weapon has a conservative estimate of sub 1MOA accuracy at {{convert|1200|m|yd|abbr=on}}.<ref>{{cite web|url=https://www.guancha.cn/military-affairs/2018_11_09_478913.shtml |title=敢于紧盯强敌 敢于超越强敌：北方新型8.6毫米狙击枪 |website=Guancha |date=8 November 2018}}</ref>
In Chinese military service, the 8.6×70mm variant of the CS/LR35 received the designation QBU-202 with its scope designated QMK-201 variable zoom optics. 7.62×51mm variant of the CS/LR35 received designation QBU-203 with its scope designated QMK-201A.<ref name="netease">{{cite web|url=https://www.163.com/dy/article/GGJ7GON405238FA2.html | title=博物馆里的新枪族，见证轻武器发展，解放军单兵武器未来可期 |website=NetEase News |date=4 August 2021 |language=Chinese}}</ref><ref>{{cite web|url=https://www.china-arms.com/2021/06/qbu203-qjy201-leaked/ |title=QBU-203 sniper rifle and QJY-201 machine gun leaked |website=China-Arms |date=10 June 2021}}</ref>
Both CS/LR35 variants with minor modifications were rebranded as CS/LR24 (for 8.6×70mm Lapua Magnum) and CS/LR4B (for 7.62×51mm).<ref name="cslr24">{{cite web|url=https://club.6parkbbs.com/military/index.php?app=forum&act=threadview&tid=17420567 |title=新机枪外贸？解放军还没换装完，不怕泄密吗？ |website=6park |date= 1 January 2023 }}</ref>
