Hello PR Crew!
I'm hoping this is the right place to ask this question. I have a Savage model 10 fcp and the threads on the barrel are not 5/8 x 24 that seem to be common for .308. They might be ( I don't have a way of truly checking ) 9/16 x 24 ( but a course thread 24 ) at least I think this is the thread pitch. I have a 9/16 x 24 muzzle break ( fine tread 24 ) that wants to fit, except for the fine / course thread interference. I'm looking to get a thread protector made by someone local. My main question ( somewhat out of curiosity, but also in case I need the information) did Savage have a certain in house proprietary thread size that they used? This is a used rifle. Came with a horrible little aftermarket muzzle break on it. I was also told by two different individuals that Savage will do their own things from time to time, and not stick to commonality that everyone else does - like uncommon thread pitch and size. In the long run, I'm going to have to barrel cut down slightly and have it threaded to 5/8 24. But as time and money permits, a thread protector is a better option for me right now. Thanks, and have a great day all! |
| Mine is threaded 5/8x24. Your course thread 24 vs fine thread 24 doesn't make any sense. The 24 is a measure of threads per inch. Coarse and fine are typically used in reference to bolt threads. For example a 3/8" bolt comes in 2 standard thread sizes 3/8x16 tpi (UNC "coarse") and 3/8x24 tpi (UNF "fine). |

If it's not 5/8x24 the suppressor mount in that thread pitch I have had on there since I got the rifle hasn't been able to tell a difference. Threaded right on very smoothly and hasn't been a problem.
They also come from the factory with a thread protector. If yours it truly not 5/8x24 I think your barrel may have been rethreaded. |

Possible they just rebarreled it too as easy as it is on a savage. Got calipers and a camera? Take some measurements of major minor and count the threads in a .5" area
If you don't have calipers, order some of go to harbor freight. Even the $10-$15 digitals are very accurate and consistent. I have plenty to choose from and I haven't seen any quirks with the cheap ones aside from only lasting a few years |

Rifle is getting new threads at a local gunsmith - it will be threaded to 5/8 x 24. And in the gunsmiths opinion, the rifle barrel was threaded by someone else, not by savage I was correct on my assumption that it was 9/16. The thread pitch was at 20 . ( gunsmith checked what was done to it ) But, I appreciate all the replies, and again, apologies for the confusion. Have a great day all! |
