The Ascend Phoenix 338ARC Pistol Developed by Hornady, the 338 ARC round delivers more energy and better terminal performance than it's 300 Blackout counter part. In fact, 338 ARC subsonic rounds (307 grain) deliver 1.5 times the energy than 300 Blackout (208 grain) with a longer effective range. Not only that, but the velocity drop shooting super sonic rounds through a short barrel vs. a long barrel is very small compared to other calibers. Combine those features together, and you have a game changer on your hands! (A Quick look into 338ARC) 338 ARC uses the 6.5 Grendel as it's parent case, so the pressures are more consistent, providing reliable cycling with both super and subsonic loads. Who wouldn't want big bore performance on an AR15 platform? Based on our Ascend Phoenix billet receivers, the Ascend Phoenix 338ARC Pistol takes the performance of the 338 ARC and combines it with high quality, ambidextrous receivers. Machined and assembled in house, you won't find a better pistol on the market. Add a Next Level suppressor to your pistol for the ultimate performance combination.
