For an m40 a3 style build, which bartlein barrel contour would be the closest? From what I have read, it looks like the #9 HIV modified is the best for the specs i have seen posted. Can I get some input.
Initially I thought that as well but I have seen the diameter at the muzzle for an M40a3 is .920 The bartlein web site has their M24/m40 barrel at .900 hence my confusion
