What is the barrel diameter at the muzzle? Is it a sporter contour or a heavier barrel?

Doc

The only left-handed RARs in 6.5 Creedmoor that I've seen advertised have the Predator style with the heavier threaded barrel and green stock.

Ruger's model number for this style is 16977.

I've read that it mics .665" at the end of the contour where the threads begin. But I don't have one in hand to confirm.

Before I had mine in hand, I called Wyatt precision(?). Home of the $30 muzzle brakesI asked what they had for the river
Predator. The fellow said if he remembered correctly. .700. They smallest 5/8-24 brakes they have are .750.

Not the same contour, but not a coke can hanging in the end either.

Ive chased my tail all week attempting to find a non Coke can brake. Seems a radial brake can be turned down to a smaller O.D. But the slotted or baffled style with directional ports can not. .750 is about as small as I have found that route

It's harrels precision, not wyatts that I was looking at.

I'm gonna order on to try. Radial ported.

Will ask if the brake can be turned down to barrel diameter.

Brownells has a forward facing, radial brake that works pretty well. I know nothing of whether it can be turned down to the barrel contour.

Andy at Hawkins Precision makes what your looking for. Everything they make is great quality!

.875" is minimal turn at Hawkins

Yup, your right, I thought he made one a little smaller, but you could turn it down a little more. The problem is the side port brakes work best the bigger they are. The radial ported brakes still work great turned down.

Ruger should of went 1/2-28 on the threads
