Brook, overall length is exactly 26.5 inches.

I realize the receiver is multi-cal, but is the barrel rated for 556 rounds?

yes it can use either the 5.56 nato or the .223 with no issues

Jeffrey, Yes Sir. The Barrel is actually stamped 5.56NATO.

What is the thread on this barrel for the flash suppressor? I need to know to order the correct thread for a suppressor.

Does this pistol accept any manufacturer’s brace?

Yes it does Cody. The buffer tube extension would need to be replaced with the "Brace" specific tube. Example : https://www.kakindustry.com/shockwave/kak-shockwave-2-0-blade-and-tube-black

I love shopping at Buds. This Diamondback rifle is so nice. It's one of my favorite firearms in my collection.

I purchased a AR15 pistol, because my friend showed me his and I had to have one. I did some research and this seemed to be a quality gun, made in the USA. Which they haven't always been. I added a angled fore grip, sights and a flashlight. This gun had not so much of even a tiny hiccup. I used 5 thirty round Magpul Gen 2 mags, perfect. The upper, lower and quad rail are all aluminum. So, it's got some weight to it. Also, the quad has rails, top and bottom and KeyMod on the sides. I did add a Shockwave brace to it. It is an awesome gun, I owned a cheaper AR15 and quickly got rid of it. This gun has the chrome lined barrel, which cleaned up really good, This is an awesome gun! Bud's is the place to purchase. Best price and I got my gun in one day. This doesn't always happen. But, this wasn't the first time a gun got to my FFL in 24 hrs. This Diamondback AR15 is an awesome gun from a awesome gun shop.
