ABSTRACT:
The present invention is a further improvement on Marshall et al. U.S. Pat. No. 3,525,172. Herein it is proposed to construct the gun barrel of two sections which are threaded together. The rifled bore of the barrel is terminated at a predetermined point and the smooth bored muzzle portion is threaded into the rifled portion at the juncture point of peak pressure between the two barrel portions. The threaded areas on each of the gun barrel sections are interrupted in a manner that facilitates quick longitudinal assembly and a rotation of the barrels by 90.degree. locks the barrels together.
