This has been a hallmark of Bartlein blanks for as long as we’ve used them, and it was great to see the same workmanship in the new design as well.īartlein is offering their carbon fiber blanks in four finish lengths (20″, 22″, 24″, and 26″), and three contours. Once in the lathe and indicated true to bore, outside diameter concentricity to bore was within. The bore finish of our blank was impeccable, with no defects found on either lands or grooves.
Bartlein marks all of their finished barrels with the final bore and groove dimensions on the breech end, and they exactly matched our results when gauging. Straightness and uniformity of the barrel was perfect. This barrel is 23″ finished, so the weight savings with the CFW is in reality about 1lb 2oz. 24″ Bartlein CFW #13 contour finished barrel in 7mm bore size, 3.0lb total weight Near identical barrel contour, #11 Medium Palma with shortened shank, in steel. This makes their carbon barrel blanks slightly heavier than that of competitors’ products, but the design features bear serious consideration if you plan to run your rifle hard. We are also told by Bartlein that the steel liner geometry under the carbon wrap is optimized for maximum support on both ends, with the knowledge that suppressor use is common and must be accounted for in the design of the barrel blank. The muzzle end also has a longer steel section, giving more support to muzzle threads for suppressor use. To that end, the breech end of their barrels features more steel to support the thread tenon in the action, and the chamber and throat during extended firing. Bartlein approaches barrel making from the perspective that accuracy and consistency are of utmost importance weight savings are secondary. The first thing we noticed on our test barrel blank was the amount of steel left on both the breech and muzzle end, compared to some of the other carbon barrel makers. Our purpose in testing was to determine if the new carbon wrapped option would live up to the reputation established by the company’s excellent steel barrels. They are well known to just flat out shoot. They are currently the most requested blank manufacturer by our customers, and for good reason. They support competitive shooters in an incredible way I cannot remember the last major PRS or NRL match I attended that did not have a Bartlein Barrel certificate on the prize table. Bartlein is an established heavyweight in the premium barrel market, holding numerous world records for accuracy across a wide range of shooting disciplines. Like many others in the precision rifle crowd, we were extremely excited to see Bartlein Barrels release their new Carbon Fiber Wrap (CFW) barrel blanks to market.
