Frequently Asked Questions

What are the key features of the Robinson Armament XCR-M SBR?

The XCR-M SBR features a 9-inch barrel chambered in .308 Winchester, a reliable short-stroke piston gas system, ambidextrous safety, magazine release, and bolt release. It also has a non-reciprocating charging handle and a quick-change barrel system retained by a single Allen screw.

How does the XCR-M's gas system work?

The XCR-M utilizes a short-stroke gas piston system. In this design, the piston strikes the bolt carrier group to initiate the action cycle but does not travel the full length of its stroke with the bolt carrier, which helps keep the system cleaner and cooler.

What is the accuracy of the Robinson Armament XCR-M SBR?

Accuracy from the 9-inch .308 barrel of the XCR-M was reported as modest, with the rifle producing 4-5 inch groups at 100 yards. The muzzle brake effectively reduces felt recoil and blast.

Why is the XCR platform popular in Canada?

The XCR platform is popular in Canada because it is not classified as an AR-15 variant. This classification allows it to be legally configured and used in certain competitive shooting events, such as 'Heavy Metal' 3-gun competitions, often utilizing its pistol magazine compatibility.
