Power Custom replacement barrel V-blocks are fully CNC machined from 416 stainless steel and hardened to RC-28. The replacement barrel V-block is designed to help eliminate the problem of barrel “drop” caused by the 10/22®’s slip-in barrel design. The V-block helps to maintain a steady pressure to ensure a tight barrel-to-receiver fit for improved accuracy.
