Description
The Robinson Armament Co. XCR is a multi-caliber, gas piston weapon system designed in 2004 by Alex J. Robinson of Robinson Armament Co. It was developed for the U.S. Special Operations Command (SOCOM) to meet the requirements of the SOF Combat Assault Rifle, or SCAR competition, but was disqualified due to the late delivery of blank firing adapters. It has been offered to law enforcement, the military, and the general public since 2006. Production of the XCR-L variant began in mid-2006. The 6.8mm Remington SPC variant began shipping in November 2007, followed by 7.62×39mm rifles and conversion kits in July 2008. The XCR-M .308 and XCR-L 5.45 calibers were announced for public reveal at SHOT show 2011. Since its introduction, components of the XCR have been updated.
The XCR utilizes a gas-operated action with a long-stroke gas piston, with the gas chamber positioned above the barrel, similar to the Kalashnikov design. It features a heavy-duty bolt and extractor, patented by Robinson Arms. Its proprietary bolt is a three-lug design, which locks onto the barrel extension, designed to keep the upper receiver unstressed, which eliminates the need to check headspace when changing barrels. A steel fixed ejector inside the receiver, secured by two bolts, provides ejection at the two o'clock position, with an optimal distance cited as 15 to 20 feet depending on ammunition and gas setting.
Rifle features include:
-
Folding and telescoping M4 Carbine style stocks
-
A monolithic top Picatinny rail with side and under-barrel rails
-
A forward assist integrated into the left-side charging handle
-
STANAG 4179 type magazines
Component updates include the firing pin, a 2nd generation adjustable gas system, the hammer, an integral winter-style trigger guard, a new paddle style safety, a provision for a quick detachable sling loop, and a two-stage match trigger. An ambidextrous magazine release was demonstrated in 2010.
Variants include the XCR-L, currently available in 5.56×45mm NATO, 6.8mm Remington SPC, and 7.62×39mm calibers, with conversion kits offered, and the XCR-M is available in .308 caliber. Different sized upper receivers enabling various barrel lengths are available: Standard, supporting 11" to 18.6" barrels; Mini, 15.25" long, primarily for 9" to 10" barrels; and Micro, 13.25" long, primarily for 7.5" to 8" barrels, supporting lengths from 7.5" to 18.6". "California" versions with limitations to meet state laws are also available. An 18.6" barrel version was produced for the Canadian market, featuring the FAST stock and a five-round pinned magazine, although the XCR was reclassified as a Prohibited Firearm in Canada on May 1, 2020.
The firearm has been offered to law enforcement, the military, and the general public since 2006. It was also made available on the Canadian market prior to its reclassification as a prohibited firearm in that country.
