Savage 10 FCP-SR (2015) Base Selection

I am finishing putting together my savage build for long range. I have 500y at my house to shoot and have access to 1000y. I am simply trying to put together a accurate rifle. My last component is the scope rail. What are people's opinions on the stock rails? And based off of the components listed below and my goals would you upgrade the scope rail, and if so, what brand would you upgrade it to.

Current Build:
Savage 10 FCP-SR 24" barrel (2015)
Manners T2 w/ savage bottom detachable magazine
Seekins 30mm Low
Sig Tango 4 6-24X50 MOA/MOA (65 moa of elevation)
Silencerco Trifecta Muzzle Brake
Lone Star Precision Scope Level

Thanks for your help!

The factory supplied rail is made by EGW and is a top quality piece. It's a zero taper base, so depending on what cartridge you're shooting you may or may not need to swap it out for a 20 MOA rail.

Thank you both for your responses. I read somewhere a while ago that the factory rail was EGW but never found any other mention of it so it is good to have that confirmed.
