4 Claims. (Cl. 124-10) The invention relates to guns and forms a position of rotative adjustment. This body pordivisional of my pending application for patent tion also has struck out therefrom a lug Q which Serial No. 632,856, filed September 12, 1932. serves as a guide for inserting the cap in the The present application relates more particufalse barrel and also as a lock for retaining it larly to the construction of the removable in position. Cooperating with the cap member w shooting barrel and further to the means for O and lug Q thereof is a reinforcement member locking said shooting barrel in position and fitting within the false barrel B and this member for simultaneously controlling the closure is formed as a part of a sight member R. Thus the shot opening in a magazine barrel and varias shown, the sight member R is formed as ous other features as hereinafter set forth. an upwardly projecting flange on a cylindrical In the drawing: member S which extends part way around Fig. l is a side elevation of the gun; within the false barrel B, leaving a gap which Fig. 2 is a longitudinal section through the forms an entrance channel T for the lug Q. shooting barrel and magazine; The portion S is also cut away at U to permit Fig. 3 is a cross section on line 33 of Fig. 2; the turning of the cap K after the lug Q has EU Fig. 4 is an end elevation of the false barrel passed through the channel T, and the edges with the true barrel removed.
