The Robinson Armament Co. XCR is a multi-caliber, gas piston weapon system developed by Robinson Armament Co. for U.S. Special Operations Command (SOCOM) to fill the requirements of the SOF Combat Assault Rifle,[5] or SCAR competition, but was disqualified on a technicality due to late delivery of blank firing adapters. It has been offered to law enforcement, the military, and the general public since 2006.[6][7]
The XCR utilizes a heavy duty bolt and extractor connected to a long stroke type gas piston. The bolt and extractor are designed and patented by Robinson Arms, and promoted as offering higher performance over eight lug M16/M4 type bolts. Other features include a folding stock, telescoping M4 Carbine style stocks, monolithic top Picatinny rail with side and under-barrel rails, and forward assist integrated into left-side charging handle.

The XCR rifle utilizes a gas-operated action with a long-stroke gas piston, similar to the Kalashnikov design, and the gas chamber is positioned above the barrel.
Its proprietary bolt features a three-lug design, securely locking onto the barrel extension, which helps to keep the upper receiver unstressed. The design eliminates the need to check headspace when changing barrels. The rifle incorporates a steel fixed ejector inside the receiver, secured by two bolts, which the manufacturer claims results in stronger ejection compared to the AR-15's spring-loaded ejector. Ejection pattern occurs at the two o'clock position relative to the operator, with an optimal distance of 15 to 20 feet, depending on the ammunition type and gas setting.[8]
The XCR uses STANAG 4179 type magazines.
The XCR was designed in 2004 by Alex J. Robinson of Robinson Armament Co. Production of the XCR-L variant of the rifle began in mid-2006.
The XCR-L is currently available in 5.56×45mm NATO, 6.8mm Remington SPC and 7.62×39mm calibers.[9] Each of these calibers is available in kit form for converting an existing rifle to one of the other calibers.
The XCR-M .308 was officially confirmed via Robinson Arms email circulation to a public reveal at SHOT show 2011. The 6.8mm Remington SPC variant began shipping in November 2007.[10]
The 7.62×39mm rifles and conversion kits began shipping in July 2008.[10]
In August 2009 Robinson Arms began shipping 3 different sized upper receivers enabling PDW and pistol style variants:[11]
Variants are also available in "California" versions which are limited to meet the more restrictive State of California firearms laws.
Robinson Armament also produced an 18.6" barrel version for the Canadian market. The XCR rifles intended for the Canadian market were shipped with the FAST stock (fully adjustable stock), although aftermarket stocks are available as an accessory. These rifles shipped with a single magazine pinned to accept only five rounds. On May 1, 2020, the XCR was reclassified as a Prohibited Firearm and is no longer legal to import or sell in Canada.[12]
Since its introduction in 2006, components of the XCR have been updated. Most of these enhancements are available to existing XCR owners.
