Umbrella Corporation Weapons Research Group (https://www.ucwrg.com/index/) is coming out with their own line of barrels. These are Cold Hammer Forged Stainless barrels. I'm not sure anyone else has offered a Stainless CHF barrel before. To match the barrels, they are also offering gas blocks made from stainless steel. Everything I've owned from Umbrella Corporation Weapons Research Group (https://www.ucwrg.com/index/) has been top notch and expect these to be no different. Look for these later this year. Keep up with the updates on their website here (https://www.ucwrg.com/index).
From Umbrella Corporation Weapons Research Group (https://www.ucwrg.com/index/):
Here's a sneak peek at a barrel line we've been working on since 2007 (prototype shown). As far as we know, we are the first to cold hammer forge AR rifle barrels from 15Cr-5Ni (15-5PH) stainless steel. The taper pinned gas blocks are also machined from 15-5PH stainless and the extensions are cut from custom 465 stainless steel. The alloys come from our friends at Carpenter Technology Corp and represent the finest aerospace steel on the market. This 15-5 Vacuum Arc Re-melted alloy exhibits an extremely uniform microstructure (superior to 17-4PH, 416R, 410) providing advanced resistance to throat erosion. These barrels are high pressure tested and undergo both ultrasonic and magnetic particle inspection. While our initial barrels available this quarter will be cold rotary hammer forged from 41V45//CMV mil-spec steel with salt bath nitride surface and bore (same test protocol as the 15-5 models), these stainless barrels will most likely follow Q2 depending on production capacity.
