Ive installed a few of them and all were giant sucesses. They do what is claimed on their website, yes they cost double that of a regular barrel but your supose to get at least double
the life from them as well.
I talk to mike now and then and he is very easy to deal with and busy with other govt contracts also.
The biggest problem in getting a ABS barrel is not ABS itself, you or he first have to order a
barrel blank contoured to his specs and there are only a few i would trust in doing this. He dont
want no button barrels for this process so that shortens the list of barrel makers. If when they
arrive at his shop for wrapping and they dont pass his inspection they go back to the maker. Remember, ABS dont like to do any barrel contouring in their shop, the barrels are pre turned when they get them.
So you have to go through the process of first getting the blank, barrel makers these days lets
see, 8-24 weeks if your lucky, then its shipped to ABS, he usually gets them out in 4-6 weeks depending on how backed up he is. My last ABS barrel from start to finish was about 10 weeks.
I had Benchmark make the blank and ship it out to be cut rifled, it was inspected there before shipping to me. I then looked it over and passed my inspection and sent it down to Mike at ABS, it passed his inspection. He had it back to me in several weeks. 416cal 32" 1.430 breech section, straight taper to 1.200" at the muzzle, 6# Its a giant of a barrel.
I offer the barrels as an option for those who want a "one of a kind" build or are looking to shave weight and not loose accuracy by going to a light contour steel barrel.
Goodgrouper has done extensive tests on the cooling effects of the ABS barrels, the only test i did was shoot the darn things and they all have been sub moa barrels. Long range tests in the 338cals i have built all were under the MOA standard at extreme distances 1200yds+
I am getting ready to test my new 416VM rifle soon, results will be posted later.
I wouldnt hesitate to order a ABS barrel, if its a price issue then stay with steel. If you want to build your dream gun and or you dont want to break your back carring that 16# rifle up a mountain side then Carbon is the way to go, be it Christiansen or ABS. You can have the large dia barrel at the weight of a standard light rifle.
Here is my new creation
416VM
