Just saw this on their site. Here are the specs:
“Our new Drop in barrel for the CZ457 and 455. The barrel is a 24” straight 1.180” profile with 1:16 twist made from a premium 416 stainless steel blank. Our barrels are lead lapped to provide exceptional precision. We use a 22 LR Match chamber for a great balance of precision and reliability in a repeater. The barrel is finished off with a target crown rather than threads to prevent the bore from opening up for maximum precision. We include bolt shims to set the headspace to your preferred ammunition. LEAD TIME IS 14 WEEKS.”
Anyone know more on these? Brand new?
