OE-SPEC- 5.56 12.5" Mid Gas, AR15 Barrel- Nitride

I had been looking for a 12.5" mid length barrel for some time after reading an article about barrel length compared to velocity as well as being unimpressed with the carbine gas systems on many of the shorter pistol/SBR barrel lengths. Everything I looked at was a higher price than what I was willing to pay for what I considered to be a "truck gun". After receiving, installing and shooting the barrel I'm nothing short of impressed with the quality from fit and finish to accuracy. The only thing that I noticed that might be an issue is how hard the steel is when I dimpled it for the gas block as I had to buy a cobalt bit and that still seemed to have a hard time but I got it done and again I'm impressed and considering buying another. Thank you

I put this on what I had planned to be a beater/training rifle and honestly it seems a little too good for that... but that just means it’s gonna be put through it’s paces. I expected the finish or machining to be a little sub par for the price, but it is very aesthetically appealing. The tolerances all seem to be right on, the threads are clean and the gas port seems to be appropriate for the short dwell time without being overgassed. I’m running it with an adjustable gas block, A5 buffer tube, the 3.8oz buffer (A5H0, the lightest VLTOR offers) and an 8.2oz lightweight BCG and even with such lightweight components, it barely had to restrict the gas flow. No feeding or extraction issues with brass or steel yet. Haven’t had a chance to really test out accuracy, all I’ve done is get the build together and tuned for reliable cycling and I was just shooting at a torso sized rock I decided I didn’t particularly like that was about 150yds away with unzeroed iron sights and I didn’t have any problems tagging it repeatedly.

Got this to make a 12.5 Dissipator of sorts. This barrel are run 100% so far and I've put about 400rds of wolf steel case threw it. I had some concerns if it was going to cycle reliably with wolf but it has been great no issues to date. The only thing I wish they would habe offered is an A2 FSB option, I had to drill and pin my own. But this is I. My opinion much better then is more popular 10.5 inch brother. More velocity without giving up anything in the mobility dept. And in my case the ability to put midlength handguard on the barrel, which allows me to extend my hand out further. And it looks badass!!!!

One of the cleanest and cost effective barrels on the market today KAK industries hits it out the ball park again. I ordered the mid length barrel on this 12.5 inch and was told not to due to Lag time and cycling issues but experienced none I've shot everything from Blackhills match ammo to steel casing TulAmmo with no jams, misfires or cycling issues with over 1000 rounds and just as accurate as my blackhole weaponry stainless steel $375 barrel. excellent Product !!!!

Everybody said mid length gas on 12.5" barrel wouldn't cycle. Well, I built it anyway. It cycles flawlessly and last round holds open every time. Night and day difference from my 10.5" carbine gas barrel. The mid length shoots much smoother. The fit and finish of the barrel is excellent.

Nice hard barrel. I had to order harder bits just to drill dimoles for my gas block screws.
