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.

Bought this barrel with hopes of having a good truck gun. This barrel took my build over the top. Bought the hole package offered and installed an H3 Armaspec stealth buffer spring and no problems with the first 10 rounds. Did the barrel break in process and loaded my 60 round magazine and that "pistol" gathered a crowd at the range. Hands down the bad ass barrel ever owned, and I own many.
