This set of calibers is 7.62mm. allows to make an objective assessment of the diameter of the rifle barrel bore. This set provides verification of the diameter of the barrels in the range from 7.61mm to 7.67mm and 7.772mm, with an accuracy of 0.01mm. Each of the calibers has its own strictly defined diameter. This allows you to check and reject the barrels of such weapons with the required accuracy in the entire range of current sizes. Attention! It should be remembered that the cleaner the inner surface of the barrel, the more accurate the result obtained and the longer the service life of the caliber set.
