got mine today its a unprofiled unturned blank in hopefully a 311 bore ( I havent slughed it but sticking a bullet down in id say its close. its saw cut on bolth ends. Ill have to get it in the lathe and turn it on centers to see how consintric it is. but for $36 dollars shipped it will make a barrel for any AK as long as its under 30" it looks just like the picture above
when i get time ill chamber it and make sure its true to the centers and if it is ill turn the trunion end to 23 mm and leave the rest large and crown it and do a bull barrel target barrel with out gas port or GB and see how well it can shoot. the out side is a smooth black. looks like one inch rod with a hole in it. hope fully it will be fairly consentric.
IMOO the ads says profled and to me that means even if its straight it should be turned on centers. if its a straight or tapered or steped profile it should have been turned. this should be a advertised as a .311 20"x1" OD unturned blank with the correct twist rate given. Im not going to biuth as its what I really wanted but I can see how others will be disipointed. If it shoots i may get a few more to set up as plug and play target barrels for sale. Id like to be able to buy other calibur blanks like this for that price. a 5.45 for instance woud be nice as well as a 223 and .308. Id but a bunch of 6.5mm" blanks as well for that price.
