T97NSR Barrel Twist?

[Travis Bickle]

I'm about to go zero my new to me T97NSR tomorrow.

I have a couple different .223 Rem manufacturers and grains to try out in her.

Will be zeroing with a 62gr projectile (hopefully)

I have searched for information on them but could not find an honest answer, just forum speculation etc

What is the twist rate of the T97NSR barrel?

Also, anyone know for sure wether or not the barrel is chrome lined?

Thanks

1/7 and chromed

Hi there. Stick your cleaning rod and brush into barrel ensuring brush is in chamber, now mark the rod directly below front sight, make a radial mark(only I/8 of radius) then pull rod out slowly until mark made on rod is again lined up with front sight. Take tape measure and measure from end of barrel to the mark. That measurement is your twist rate. Not very scientific however it is accurate enough. Hope this helps
