I am no longer an advocate of naked barrel muzzle jumping platforms. I even install brakes on my 6.5mm Creedmoor builds to stop muzzle jump. Quicker more accurate follow up shots. To assist a GOOD installation index for great control a good crush washer and temper is required. These are very consistent and easier to get the proper crush. I highly recommend them. I will continue to use MCARBO for this product.
