5" 5.56 NATO MICRO 1:5 5R

The barrel is awesome. I went with the matching gas tube, and an adjustable gas block. I'm running a micro buffer system, and a binary trigger... a combination thats asking for trouble, but it required surprisingly little tuning, and runs flawlessly.

This barrel flat out works. You read a lot of negatives about short AR barrels in 556 but this barrel is a tack driver. My AR build turned out wonderful with this barrel. My barrel came with gas block and tube. Looks like you order them separately or as an add on. I replaced the gas block with adj gas block. My order took a week or two to process but I received it. Have faith in your order received.

So i bought these barrels and I bought a KAK barrel. I will say that hitman Barrels do not blow gas back in the shooters face like a KAK barrel does. Super fast shipping, darn good barrels. Great value! Look forward to buying more.
