Looks good, I used an 18" last season. You will definitely want hearing protection when hunting. I went out the first time, shot 5 or 6 times, and my ears rang for weeks. I wasn't used to that happening with 24" barrels.
My Sabre 18" 1/7 shoots the 53 vmax as well as 75 tap with a 4moa trajectory out to 300 and my opinion is the 18" is the best barrel for hunting rig doubling as sporting rifle
I shoot a 16" Rock River 1/9 and it loves 55 grain zmax. It's crazy because I've researched the vmax and zmax bullets and basically everything I've read stated they are identical however the zmax factory load groups better then the vmax factory.
I'm putting a silencerco can on it here in a few months. Hopefully it makes it a little quieter.
Now you're talking...I have 3 .204's and 4 .223's I've built and working on another.223 now. When I go to shoot though...99% of the time,I grab a .204. I even enjoy reloading different loads for it too. All my .204's have 1:12 twist and wish now I would have built one with a faster twist. Maybe the next build I will??? Good luck and enjoy what ever AR you decide on and be safe!
