BRT OPTIMUM Barrels

[Biggy]

I'll have to break out the calipers when I get home. I have the SF SOCOM muzzle brake on the shelf, and approximately 9 weeks until the can arrives. The brake is listed at 2.7", hopefully that's an accurate measurement.

*If*, the barrel is right at 14.000" inches, and *if* the barrel's thread length from the end of the barrel to the shoulder is the standard .625"length spec and *if* your SF SOCOM brake is right at 2.7" inches long, it should put the barrels total length right at 16.075" measured from the bolt face to the end of the muzzle.

It'll be sent to be pinned and welded by someone who will ensure it's within regs. As long as the threads are standard, I expect it to work. I threaded the brake onto a barrel and it added 2.1" at a minimum, no timing involved. If the project doesn't work out I'll use my current 16" Optimum barrel with the Warcomp installed as a host until we get the 14" barrel sorted out. I shoot 3-4k rifle a year, so barrels get replaced eventually.

Our lengths are accurate and that math is correct.

Additionally, there will be a timing shim.

Also, while the "name plate" length is correctly measured from breech face to muzzle, the ATF measures to the bolt face, which adds ~.125.

In short, this combo should easily be long enough.

For the next batch, we could do either 14.0 or 14.5

Currently leaning toward 14.5" with 1/2-28 threads to ensure compatibility with the most muzzle devices for pinning.

Thoughts?

What would the timeline be on that? Two months, 12?

Definitely measure the brake with calipers to verify. The 3 prong warcomp was longer than the listed length on Surefire's website when I measured it.

Very interested in a 14.5.” It seems to me that most muzzle devices are the same OAL with regards to 1/2-28 vs 5/8-24 or am I wrong?

I'd prefer the 14.0", but would buy either.

Just finished up a Suppressor Compatibility Chart for 5/8-24 threads.

Looks like Sig and Surefire are the only holdouts.

I'd definitely be into a 14.5 with 1/2x28 threads to try on my URGI, just curious on the timeline as I already have a WarComp waiting to be put on it.
