Re: Carbon wrapping a Barrel
Just my 2 cents as well, but I've been dealing with Mike at ABS for many years now, and have a few things to say.
One, Mike has been more then busy, he's been swamped, and it was worse then you can imagine. I have visited his shop 3 times in total and he just could not keep up with the phone calls AND work on the barrels...he is the only guy who does the wrapping, or was.
Second, and I don't know how much I can share, but he got a HUGE contract with a branch of the military that ate his time like no tomorrow. They needed data and testing done daily, with some very specific needs, so that just killed his phone time. None the less, he did return phone calls and worked out issues, if you kept up on him
Now
That's all a thing of the past. He has moved into a much larger facility and can finally keep up, and the customer service is really getting good. Mike is a stand-up man and has stood behind his word every time. I have at least 3 barrels from him, and not a one is greater then 1/2 MOA.
To note, a 22-250AI that's shooting over 5000fps and is 1/2" up to 300 yards all day long, and it never gets hot! I have a Carbon 15 4lb 5.56 with the Wylde chamber that I've seen (not my shooting, I'm not that good) shooting .2-.25" groups at 200 yards with Hornady TAP ammunition, and it was more then once! Not to mention is has over 1200 rounds through it and shows literally zero throat erosion, and is still as accurate as the day I first shot it.
But the best testimony I have is the 375 RUM I had. It use to sport a 34" Pac-Nor straight profile that was just under .9" at the muzzle. That barrel had 6 very large(deep) 3/8" flutes running the entire length, and it weighed 17lbs flat...it now is 11.65lbs, cutting 5.35lbs off a fluted barrel!!!! It use to be a 1MOA barrel using the 260 Accubond bullets (my plinking/breaking bullets) and now is 1/2", with either of the 4 bullets I've run in it...it's sold now, and I am very sad, but one has to do what one has to do.
With regards to that military project he was working on...I seen the barrels, and the data. He once did a non-stop 1000 round belt through an M249 (I believe) and the barrel temperature was no more then 540F, which, by the way, showed no damage. It was cool to the touch in about 5 minutes or slightly less, and was fine. He has also had a custom lined barrel go over 47,000 rounds! No joke, honestly! It was on an M4, but I have no idea where the barrel is today. The point is, his barrels are the finest stuff out there, and you just can't argue with that.
