A semi-automatic rifle has a main body and a barrel group. The barrel group has a barrel extending along a barrel axis, engaged at one end with the main body, a rib extending along the barrel axis, engaged with the barrel in an upper region, and a guide device for supporting weapon accessories, extending parallel to the barrel axis. The guide device engages the rib in a region proximal to the main body.

WHAT IS CLAIMED IS:

 a barrel extending along a barrel axis, engaged at one end with the main body;   a rib extending along the barrel axis, engaged with the barrel in an upper region; and   a guide device for supporting weapon accessories, extending parallel to the barrel axis, wherein the guide device engages the rib in a region proximal to the main body.   
     
     
         2 . The semi-automatic rifle of  claim 1 , wherein the main body is made of polymer material, optionally the polymer material being glass filled polyamide, and wherein the barrel is made of metal material, optionally the metal material being steel alloy.  
     
     
         3 . The semi-automatic rifle of  claim 2 , wherein the main body comprises a metal insert embedded in the main body made of polymer material, and wherein the metal insert is integrally engageable by the barrel. 
     
     
         4 . The semi-automatic rifle of  claim 1 , wherein the guide device also extends in length over a segment above the main body. 
     
     
         5 . The semi-automatic rifle of  claim 1 , wherein the guide device comprises an upper wall, and a right wing and a left wing extending from the upper wall, delimiting a longitudinal hollow in which the rib extends. 
     
     
         6 . The semi-automatic rifle of  claim 5 , wherein the longitudinal hollow is shaped, in cross-section, complementarily to the rib. 
     
     
         7 . The semi-automatic rifle of  claim 6 , wherein the guide device is couplable to the rib by a dovetail coupling. 
     
     
         8 . The semi-automatic rifle of  claim 1 , wherein the rib comprises one or more concave portions extending in height, and the guide device comprises convex portions suitable for being housed in the one or more concave portions. 
     
     
         9 . The semi-automatic rifle of  claim 1 , wherein the barrel group further comprises at least one transverse fastening element suitable for engaging the rib and the guide device. 
     
     
         10 . The semi-automatic rifle of  claim 9 , wherein the barrel group comprises two transverse fastening elements, mutually axially spaced apart, suitable for engaging the rib and the guide device. 
     
     
         11 . The semi-automatic rifle of  claim 1 , further comprising at least one transverse quick fastening member, optionally for snap engagement of the guide device on the rib. 
     
     
         12 . The semi-automatic rifle of  claim 1 , wherein the guide device is of a Picatinny coupling type. 
     
     
         13 . The semi-automatic rifle of  claim 2 , wherein the rib is made of metal material, optionally the metal material being steel alloy. 
     
     
         14 . The semi-automatic rifle of  claim 2 , wherein guide device is made of metal material, optionally the metal material being steel alloy.
