Definitions

  • the extension can be made as apart of the muzzle or it can be separately attached thereto, all of which will be clearly under stood from the description which follows.
  • Figure 1 is a side elevation of a rifle provided with my improved attachment.
  • Fig. 2 is a longitudinal section of the attachment in its removable form as applied to the barrel of a firearm.
  • Fig. 3 is an end view thereof.
  • Fig.4 is a broken perspective showing the extension embodying my improvement inte ral with the barrel of a weapon.
  • ig. 5 is a longitudinal section of a flash diminishing tube formed to embody my invention.
  • I provide a ring or ferrule 10 which screws to the threaded end 11 of the barrel of the firearm, and a lipor extension 12 projects forward from the under side of the rlng so as to receive the impact of air and gases as they expand on leaving the muzzle of the weapon.
  • the lip or extension 12 corresponds in curvature to the curve of the barrel, and that there is a step-down as shown at 13 between the bore of the barrel and the inner surface of the lip or extension 12, that is to say, that the inner wall of the lip or.
  • extension 12 represents a longer radius from the center of the bore of the barrel than does the wall of said bore, and I have found in practice that the changing of this radius has considerable effect onthe action whenthe weapon is fired.
  • the attachment is screwed or otherwise detachably fastened to the barrel, it can be turned a little to the right or left, and this will cause a slight movement of the muzzle in a corresponding direction, and the impact of the expanding gases will obviously be stronger in the same direction so that if the tendency is for the weapon to rise and also move to the right as quently the case, the extension can be made below the muzzle and a little .to the left, and thus the aforesaid tendency will be counteracted.
  • Fig. 5 I have shown a barrel fitted with a. tube 15 which is screwed thereto and which is sometimes used to diminish the flash of a firearm, which it does by permitting the gases to expand and confining them during such expansion. If the upper and forward part of this tube is cut away as at 16 an extension 17 is produced which has the effect above noted, although the action is not as good as in the cases where the extension is connected directly to the muzzle of the Weapon.
  • the structure shown in Figs. 1 to 4 acts better as a flash condenser than the usual tubular flash absorbers.
  • An accuracy attachment for firearms comprising a lip or extension directly on the extreme end of the barrel and entirely forward thereof and projecting forward therefrom generally parallel with the bore but offset with relation thereto and arranged to provide free escape for the gases issuing from the barrel in all'directions opposite the lip.
  • An accuracy attachment for firearms comprising a lip or extension rigid on the extreme end of the barrel and lying entirely forward thereof, said li being transversely curved, offset with relatlo'n to the bore of the barrel so that the inner wall of the extension possesses a longer radius with relation to the axis of the barrel than does the wall of the bore of said barrel, and the space above the lip being left free and unobstructed.
