[QUOTE="QuietTexan, post: 2085709, member: 116181"] What calibers, and what are the actual barrel ODs? The holes themselves shouldn't be a problem, if they bottom out higher than the major diameter of the threading they'll be entirely cut out anyways. You should be able to measure that with a set of calipers. You might run into the problem where large enough threads don't leave enough shoulder to mount to, and small enough threads don't leave enough barrel around the bore. Unless you have 0.725" or more OD you aren't getting 5/8X24 threads. If you have a .308 cal barrel cutting 1/2x28 threads is a no go because the treads would be tight to the bore. 9/16x24 is the middle ground, usually functional from .243-.308 calibers, but you need 0.662 OD which is larger than lighter weight sporter contours. Magnum sporter should be 0.650", so you have options there. 1/2x28 will work on calibers under .308. TBAC provides their recommended specs with minimum barrel OD by threading: [URL unfurl="true"]https://thunderbeastarms.com/tech/thread-specifications[/URL] [/QUOTE]
