Basically, the HK437 is the .300BLK variant …

By Toby Melville September 7, 2022 The necessity to carry ammunition for your firearm is an essential requirement. An individual must be able to feed the weapon they fight with, or find themselves depleted of ammunition quickly. The other side of this issue is space. There’s only so much room on your kit. Early examples in the War on Terror …

By David Crane david (at) defensereview (dot) com December 27, 2020 Back in 2011 and 2013, DefenseReview (DR) published pieces on the Sikorsky X2 coaxial/dual-rotor compound helicopter technology demonstrator and Sikorsky S-97 Raider dual rotor/coaxial compound helicopter concept, here and here. Well, all these years later, it’s being reported that “the Army is taking its final steps before starting a …

By Jeff Gurwitch July 7, 2020 The M4//M4A1/M16/AR-15 has proven to be one hell of a rifle/carbine. I’ve carried it with total confidence, and have employed it pretty successfully during my many tours overseas with U.S. Army Special Forces. The inline design and low height above bore still put it ahead of just about every military rifle that’s come out …

But the main reason for this is that the majority of adjustable gas blocks rely …

While modern bipods work well, they also add extra weight and bulk to the front of the rifle. And, bags designed for stabilizing the rifle are not always practical for carrying …

By David Crane david (at) defensereview (dot) com October 10, 2017 While DefenseReview (DR) was at the Handl Defense booth at SOFIC (Special Operations Forces Industryi Conference) 2017, we got to check out the Haley Strategic Partners HSP Skimmer Trigger and HSP Th1rte3n Sights for for Glock 9mm combat/tactical pistols, and they looked pretty good.
