AR SBR build

[FredBear86]

Wanting to build an AR SBR with a suppressor for deer hunting. What caliber should I go with? 223, 300 blk out, 6.5 grendel? Really wanna stay with an 8.5 inch barrel so total length stays under 16 inches. This kinda knocks out the grendel. This gun will be used on shots 50 and in. Possibly would do a 100 yard shot if the gun would do it, but mostly just want something to carry for close range shots in the woods. What's some recommendations?

IMO, .223/5.56 you want supersonic bullets, not .300 bo. The .22 ARC might be a bit faster, but I would not feel the need to go with a bigger case out to 100 yards max. You also have to start looking at barrel length for the suppressor you choose.

I am going to build a 10” upper in .223 Wylde (eventually) for that same thing.

For 50-100 and in, a 10.5 223/5.56 works great. Wouldn’t go shorter than that. I tested mine out for the first time this year and shot a couple of does. Both with 77 tmk’s. Performed excellently on both and was a dream to carry and maneuver in the tree stand. Even with a can on it. And a big bonus: practice ammo is cheap.

This sounds like an awesome project.
