This includes cutting/crowning as well as threading. This service is for bolt gun barreled actions, or an barrel attached to a serial numbered receiver. Threads will be concentric to the bore. Threads are either standard .400 for pistol caliber or .600 for rifle caliber. There are no custom thread length options. Do NOT send the complete rifle – just send your barreled action without the stock, scope base, trigger and bolt. There is an additional $50 disassembly-reassembly fee if we have to remove any of the above mentioned items. If you want the barrel shortened note length in the comment section at checkout. When barrels are cut, they are all measured from a closed bolt face as the only standard measurement we use. There are some we cannot do. Ruger Mini 14, Ruger 77 series, SKS/AKs, M1A/M14, and HK we cannot do. If you send any firearm, you must include a copy of a photo ID. The address on the photo ID is the address where we will return ship the firearm. No exceptions. Turn around time for this service is 7-10 business days.
