Johnny, yes sir, you can shoot this ammo thru your Tread with no issues. Have a great day!

Well, Josh T. Really explained it well so not much more for me to add except...
Load them up & Send them!!!

Johnny, yes it will fit and function just fine. Normally though 1:8 twist ratios work well with medium to heavy grain ammo like 55-68 grain for best accuracy. Lighter 40 grain ammo works well in 1:9 twist and heavy grain ammo like 68-75+ works well in 1:7 twists. It doesn't hurt to experiment with different grain weights though because I've had AR's with 1:7 twist like lighter ammo and 1:9 like heavier ammo. I'd recommend buying a box or two and test it out, if it's accurate then stock up. If interested here's a link to 55grain polymer tipped ammo that might be better suited for your 1:8 twist ratio.

Hi Johnny, yes Sir it will no issue. I have several 1 in 8 Twist Rate AR's and the Winchester 40g varmintX polymer tip, Fiocchi 40gr polymer tip are laser accurate through this twist rate. Cheers and stay safe!
