Most Recent Reviews A Perfect fit for the 8.6 Blackout barrel by cerisecons, Verified Owner, July 11, 2024
I needed a Keymo/Keymicro brake for my DeadAir Wolfman to use on my 8.6 Blackout in 5/8x24. After considering drilling out my 30 Cal(.340) Keymo brake, I did some research and found this item. It fits great at will test soon!
Most Recent Reviews Keymo is the best!! by Ringinthesteel, Verified Owner, April 23, 2024
Great at reducing recoil and perfect for a quick mount for Dead Air Keymo cans.
Most Recent Reviews Excellent Product by Ringinthesteel, Verified Owner, April 23, 2024
I have these on several of my m-lok riffles. They really help hold the riffle against your shoulder and maintain control against the recoil.
