Is this a shouldered pre fit? Or does it require the nut and go no go gauges ?

Expert Answer
A
Answered by Jonathan D., Gear Expert, from IL, United States, on December 11, 2019

These are shouldered. They will require a nut and it is advised to check headspacing with go and no-go gauges.

Q
Morgan, guest, from KY, United States, asked on August 18, 2020

They look like shouldered barrels in the picture, if that’s the case, they can’t be for the origin and TL3. Which are they?

A
Answered by Brandon, member, from UT, United States, on March 10, 2021

These are pre-fit Zermatt Arms shouldered barrels for the TL3/SR3. The barrels are specific to the action type/length and are not interchangeable, but Proof makes installation easy on these by just threading it on, torque it down, double check headspace and you should be good to go.

I want to mate this barrel with a carbine-length gas piston, but your product description doesn't say at what length it is ported.

A
Answered by Brandon, member, from UT, United States, on March 10, 2021

These are pre-fit Zermatt Arms shouldered barrels for the TL3/SR3 actions. This barrel is not ported for a gas system, and is intended for use in bolt action rifles.

Q
Rich, member, from KY, United States, asked on June 25, 2019

Will this fit Rem 700?

A
Answered by Matt G., member, from SC, United States, on July 09, 2019

No this is a pre-fit barrel for Bighorn Arms actions which even tho they are a R700 clone they use a Savage standard/small shank barrel tenion which is 1.062"x20tpi vs R700s 1.060"x16tpi(Threads Per Inch). Rem 700 barrels can not be pre-fit unless its a Remage conversion, a few company's make a Pre-Threaded Short Chambered barrel for 700s, but IMO & many others they aren't worth getting unless you're a knowledgeable machinist with the right tools, fixtures, & gauges already. Quality 1s would cost what having a blank turned and installed would be, plus the gunsmith could go ahead and true your action as well for not much more. There's also a lpt more skill level involved vs just threading on a pre-fit and check headspace w/Go & No-Go gauges.
