How does the recoil compare on 300 BLK vs 6.5 grendel in the AR platform? I have an AR in .556, but I am building a second for the kids to learn to hunt on. Have a lightweight build mostly done, just need to decide on caliber and pick up the barrel, gas block & BCG. Shots would be inside 150 for sure with most in the 75 range where we hunt. Upper is built assuming 16" barrel or longer.

I think the recoil of the .300 is less. The 6.5 Grendel and .223/5.56 are about the same. Not enough recoil in any of them that you can't stay on target. Every rifle I've ever shot in AR platform wasn't so bad that I couldn't see the hits in the scope.
Having said that the noise will probably be worse than the recoil as was already mentioned. If you're not going to suppress it I'd go with the Grendel. If it's gonna be loud it might as well shoot faster and flatter.

AR recoil question
Very little difference in recoil to me. Probably slightly more with the Grendel. For your needs, I would definitely go with the Grendel or a 6.8 SPC. Shooting suppressed sub-sonic rounds is the only place that the .300 BLK stands out to me. I had one for a while and sold the upper to build a 6.5Last edited by Raider4044; 08-31-2018, 10:41 PM.

I used an AR 15-22 to teach my older son to shoot. Using hearing protection and a red dot he picked it all up very quickly. I liked being able to adjust the stock to have him in proper shooting position and focus on learning trigger control.
The switch to 556 from 22 was seamless. He didn’t even realize it the first time.

If your gonna build just one, it should be the Grendel.
I have guns in both calibers. For inside 100 yards I choose the 300 Blackout. The Grendel will certainly get it done but it’s such a waste of a good caliber and it’s more expensive to shoot.
If you stick with the Barnes 110 black tip bullets in the Blackout? It will most anything in Texas with ease.
