Is it possible to re-thread a 5/8-24 carbon barrel?

Thanks All. Lesson learned for me, going to do standard 5/8-24 from now on.
Just to complete your understanding here, threads are divided into classes. In the case of muzzle threads, the classes we see in gun work are 3A and 2A(A is for male threads, B for female threads). These two classes overlap, but 3A can be slightly larger than 2A, but has a smaller tolerance window. Everyone likes to see small tolerances, but there isnt a large distinction here in the case of muzzle threads. A 2A thread would fit more stuff(like a slightly smaller than proper spec muzzle device) and will function just fine. See the chart below for the 3A and 2A pitch diameters for a 5/8-24 thread. The thread is verified using thread ring gauges(Go and no-go). If the Go gauge wont thread on, the thread is too large in pitch diameter, if the No-go will thread on, the thread is too small. Don’t go buy gauges, they're stupidly expensive, just verify the shop is going to adhere to one of these classes and move on.

Some shops call out the class they're adhering to up front, such as Patriot valley arms. See the pic of their muzzle thread drop-down below. Other shops can answer the question if you ask.

Muzzle device manufactures should also be adhering to a class(3B or 2B). Shit happens though, and parts get shipped that are out of spec.

Can anybody identify this Thomas Manner rifle stock

Possibly a TF3? That one you posted isn't a TF3A as it doesn't appear to have an adjustable cheek rest, but the overall stock shape looks like it might be a TF3.


If you have the serial number in the barrel channel you could call manners and they can look it up.

M40 front sling swivel question

Nice work, not sure if you saw this thread.
Because my M40 is not a true clone, I elected to incorporate a few modifications of my own design. I was never satisfied with the original swivel arrangement, so I fabricated swivels patterned after those found on the Winchester Model 70 Super Grade, utilizing two points of attachment. These swivels are inletted into the stock, preventing any possibility of twisting, and are dimensioned to accept 1¼" slings. If this project had been intended as a fully authentic clone, my approach may have been different; however, given its nature, I chose to proceed in a manner that suited my preferences.

Geissele Cut Rifled SPR Build and Barrel Evaluation. (Part 4 (Load Development 28MAY25) Update!!!

That isn't really how dies work. The only thing you can adjust when "setting up your dies" is shoulder bump or rough equivalency to headspace. Chambers that were cut with the same reamer will have differing shoulder bump requirements most of the time. The only correct way to answer your question is using this 👇, on brass fired in the specific chamber of the Geisselle barrel you buy and then comparing it to what your die produces after sizing. No one makes 223 CLE dies or 223 Wylde dies. The biggest difference is the freebore and has nothing to do with dies or die adjustment.

Beat me to it. If I remember correctly the freebore on a CLE is a bit shorter than a Wylde which is shorter than a Match.
