SureFire Advanced Rifle Operating Core (AROC)

Friday, March 16th, 2018

We’ve mentioned SureFire’s Advanced Rifle Operating Core (AROC) in the past but now it’s in production and has been demonstrated to several customers. There is a great deal of excitement surrounding this new weapon concept. It consists of a new Upper Receiver, including Bolt Carrier Group, as well as Action Spring and Buffer, all of which can be used with existing Lower Receivers.

The AROC bolt lugs are 1/3 longer, making them twice as strong as a standard mil-spec bolt. Naturally, this requires a matching barrel extension. The longer barrel extension reduces the steep feed ramp angle as found on a standard M4, for smoother and more reliable feeding of ammunition.

The AROC Bolt Carrier has an additional .400” of travel into the receiver extension requiring a shorter buffer. Along with the additional bolt carrier travel, there is a spring loaded weight in the rear of the carrier that acts as a counter weight to increase dwell time, reducing the cyclic rate to 590-610 rpm depending on ammunition. This makes the weapon easy to control on full automatic fire, increasing accuracy and effectiveness of the weapon. The AROC’s Bolt also has a set of interlocking Inconel gas rings that never wear out. Known in stand-alone mode as the Optimized Bolt Carrier, it is available as a drop-in accessory for existing AR pattern weapons, but you won’t get all of the advantages of the full AROC.

The AROC also has a heavy duty gas tube to handle full automatic fire. The delayed unlocking of the bolt reduces carbon fouling allowing the AROC to fire thousands of rounds without cleaning or lubrication. That’s right, no lube necessary. All the testing for the AROC was done with no lubrication.

The AROC is available as a Carbine, Designated Marksman Rifle, or a box fed lightweight squad machine gun. It’s a super reliable, very controllable, upper receiver that can be added to an M4 or HK416 lower receiver. The AROC pictured has a 14.5” machine gun, chrome lined barrel. Weight is 7.9 pounds with M4 lower receiver. However, shorter and longer barrel lengths will be available as well. Shown with the SOCOM556-RC-TN contract suppressor.

The AROC will be at The USASOC Sniper Competition held at Range 37, March 22-23. For more info contact SureFire VP of Military Sales, Jamie Wiedeman, jwiedeman@surefire.com.

SureFire Field Notes is a multi-segment informational video series with tips and techniques from subject matter experts of all backgrounds. In this episode, Aaron Barruga of Guerrilla Approach discusses different approaches to stress induced training.

He utilizes lessons learned from success, but also failure in designing his training courses for domestic law enforcement and civilians.


SHOT Show 18 – SureFire Optimized Bolt Carrier

Friday, January 26th, 2018

When we last told you about the SureFire Advanced Rifle Operating Core and Optimized Bolt Carrier we weren’t sure when it would be available commercially. But SureFire had the OBC on display at SHOT Show and told us the first run are just finishing up production.


While the entire AROC consists of an enhanced Bolt Carrier Group, Barrel Extension, Buffer and Spring, the OBC is a drop-in Bolt Carrier Group which fits both piston and DI ARs.

The OBC features an internal weight which is spring loaded in both directions. This, along with the other elements, combine to offer additional travel time. When the Bolt is at the end of its stroke while using a Mil-Spec BCG, it takes 28 milliseconds for the bolt to travel back into battery. With the OBC, it’s 38 milliseconds. That slight difference is signifigant, especially when firing full auto or suppressed, or both. You’ll also notice that the gas key has a single screw. It comes with a 2 oz H2S buffer and an included Action Spring offers additional tension.
