Hello,

A couple questions regarding the RAINIER ARMS ULTRAMATCH MOD2 .223 WYLDE BARREL - 16" NITRIDE

- How reliable is the intermediate length gas system on a 16" barrel?

- Is there any standard to a intermediate length gas system? Or is this propietary?

- Can you provide measurements of the start/stop location of the gas block journal in relation to the barrel along its length?

- Were any steps taken to mitigate tool marks/burrs in the chamber/throat prior to nitride treatment?

Thank you

Thanks for reaching out.  Great questions.  

The intermediate length gas system is reliable, just as long as you are shooting good quality ammo.  

The intermediate gas length systems can vary.  For reference the length of our and Noveske's intermediate gas length tube is 13.75".  Some manufacturers, like Wilson Combat, have a shorter 13.25" intermediate length.

Our UltraMatch barrels are manufactured to be the highest quality, to our specifications, to include the care to avoid tool marks or burrs.  We offer a 100% money back guarantee within 90 days of purchase. If you aren't completely satisfied with the barrel for any reason, return it for a full refund, no questions asked.

Thank you for the reply!



Copy that. In hindsight, that was kind of a incomplete/tricky question. I know there are people out there that will try to run the absolute dirtiest, cheapest, underpowered ammo and for some reason be suprised when the reliability isn't there.



So the intermediate option gas tube from the link below should be gtg with this barrel.

I have heard nothing but excellent things about your guys UltraMatch barrels..literally..I've never seen a bad report.

My concern was that any excessive tool marking would be very difficult to smooth out once nitrided due to the increased hardness. That being said, if these shoot anything like your bare stainless UltraMatch barrels then these should be awesome plus have an extended service life. Very attractive!

Happy to help!  Let us know how your build turns out!  

Hello,

Two more questions on this barrel

- What length rail would be needed to come right to a fsb with minimal gap/gas tube exposed?

- What is the shortest rail length that would completely cover a lo pro gas block?

Thank you

I'll need to do a mock up to find out.  

If you could, that would be awesome!

Will do and will let you know!

A 12" rail will have the gas block peeking out - 12.25" should fully cover a superlative adjustable.  

Fetchin awesome, Thank you!

Most welcome!
