By Jeremy Tremp<\/a><\/p>\n In today\u2019s article, Jeremy Tremp reviews the NERO 762 Inconel muzzle brake from Walker Defense Research. This innovative muzzle device uses an additive printing technology to create something unique for 7.62x51mm NATO rifles. How does it perform? Tremp gets it onto the range for a full testing of its capabilities. The NERO 762 was provided to the author by Walker Defense Research for review.<\/em><\/p>\n W<\/span>hile I love .30-caliber semi-automatic rifles, I don\u2019t necessarily love recoil. Also, my shooting buddies don\u2019t appreciate excessive concussive force on the line.<\/p>\n If only someone had a mission to create a wonder device that could offer the best of both worlds. Queue the music and lights as Drew Walker from Walker Defense Research (WDR) enters the stage.<\/p>\n Drew is one of those engineers who refuses take no as an answer, nor does he accept status quo. WDR was founded in 2017 to \u201cReshape the landscape of firearm components and accessories with performance-based innovation.\u201d This is done by utilizing the latest manufacturing methods and exotic materials to create new and innovative products that benefit the shooter.<\/p>\n WDR is currently most known for their NERO muzzle devices, which are made utilizing the additive manufacturing process or, in layman\u2019s terms, 3D printed metal. The NERO, which stands for \u201cNeutralizing\u00a0Energy,\u00a0Remain at\u00a0Origin\u201d, is a hybrid muzzle brake & compensator and is available in 5.56, 7.62 and 9mm models. They are manufactured from Inconel, a nickel-chromium superalloy used frequently in aerospace for extreme environments (and especially for high-heat applications).<\/p>\n Intrigued, I reached out and picked up one of the NERO 762 models for my Springfield SAINT Victor .308 rifle<\/a>. It is 3\u201d long, weighs 3.9 oz., is DLC coated and has a thread pitch of 5\/8\u00d724. Now, if you\u2019ve ever seen a NERO muzzle device in the wild, you would immediately stop and take a closer look because of how unique their design is.<\/p>\n Remember that WDR desires to work on the bleeding edge of innovation and material science. As a result, they leaned on direct metal laser sintering (DMLS) to manufacture an otherwise very difficult-to-machine device.<\/p>\n The NERO is a very unorthodox-looking muzzle device with sharp angles, unique proportions and unmistakable side ports. You can tell this product was designed by an engineer with a deep understanding of fluid dynamics. It simply exists to perform its function with precision and efficiency.<\/p>\n Live The Armory Life.<\/strong> The latest content straight to your inbox plus an automatic entry to each of our monthly gun\u00a0giveaways!<\/strong><\/a><\/p>\n<\/p><\/div>\n<\/p><\/div>\n WDR says the NERO 762 is optimized for the .308 Winchester centerfire cartridge out of an 18\u201d barrel, but can also be utilized for .300 AAC Blackout, .300 Winchester Magnum and .30-06 Springfield. My Saint Victor is a 16\u201d-barrel gun, so I was curious how the device would perform with it.<\/p>\n WDR says the intent of the NERO is to reduce recoil and minimize muzzle climb, and also to manage felt concussion relative to traditional muzzle breaks. So, I decided to put it to the test. I took the SAINT Victor .308 out to the range and, after easily installing the NERO with some range tools I always carry, I was ready to see what it offered.<\/p>\n I braced myself for the \u201cthump\u201d of the .308, and I soon realized the muzzle dipped during the shot. Drew warned me that the complete lack of muzzle rise would likely reveal the fact that I brace and compensate for the recoil expected from a .308. Sure enough, there apparently had been zero muzzle rise with the shot. What kind of voodoo was this?<\/p>\n [Be sure to read our our article on different types of muzzle devices<\/a>.]<\/em><\/p>\n Looking at WDR\u2019s diagram on how the gas flows from the internal workings, the design of the NERO pulls gases away from the bullet and sends them on a different path \u2014 and one beneficial to the shooter. In their words, \u201cThis gas striking the curved blast surface is intended to create a balanced counter-recoil force that directly counteracts the rearward and upward recoil with a downward and forward counter force.\u201d<\/p>\n Their muzzle device works so well that I had to change the way I was shooting the rifle. Once I relaxed and knew what to expect, I was able to really refine my shooting stance and wring out the full benefits of the NERO. Follow-up shots were effortless, and the concussive forces to the left and right seemed to be vastly reduced.<\/p>\n Did WDR succeed in their quest to reduce recoil, minimize muzzle climb and manage felt concussion? I would say, unequivocally, yes. The NERO is a very unique and very effective way to eliminate muzzle rise from your rifles. Be warned, you will definitely need to practice a bit and get used to the new recoil impulse with the NERO. Once you\u2019ve got that down, you will be good to go with the results to show for it.<\/p>\n I can tell you that this NERO 762 is going to live on my Saint Victor .308 permanently. Its taming of the .308 is extremely impressive.<\/p>\n Editor\u2019s Note: Be sure to check out The Armory Life Forum, where you can comment about our daily articles, as well as just talk guns and gear.
