- Best Barrel for DMRUsed this barrel to build a precision rifle. Accuracy is top notch with heavy match grade pills. It does exactly what it's supposed to do. You get what you pay for.

- Tackdriver with a minimal weight penalty.This barrel is a tack driver. I’m running one cut to 14.5 with a pinned brake. Obviously not the lightest option out there but it’s simply a fantastically robust and stable platform and extremely accurate.

- OutstandingHave this on my hunting/dmr rifle. Shoots exceptionally well with any ammo I run.(55-77gr)
Doesn't make for the lightest rifle but that is not what it was designed for.Posted on
- Accuracy reigns supreme!Used this outstanding barrel on my scratch-built M4. Paired it with an Adam Arms piston. The result is my M4 easily shoots sub-MOA ... a real tack driver!

- DD 18" S2WUsed this barrel on a custom build and couldn't be happier with it. The accuracy at 100yds was sub-moa and the fit and finish is outstanding. I would consider this a bull barrel as it is a little on the heavy side but not a big deal. I built the rest of my rifle on the light side to make up for this. Overall this barrel is well worth it DD delivered another solid product I will continue to buy from them.

- Awesome accuracyI put this barrel on my first build because i knew of Daniel Defense quality and wanted an 18" mid length gun. Though it is a little heavy it shoots exceptionally well with any ammo. Weight, well in my eyes an 18" gun is an AR built for a little more Distance and not close quarters. So, I went generally light with everything else and its an awesome build. I tried the Daniel Defense stock, grip, for-grip package as well which i like as well.
