I am not sure as there have been no easily found directions on how to post a classified ad on this site but that is what I am trying to do. I have a CETME/HK 91 Type rifle for sale. It comes with 5 mags, a 2 mag belt holder and extra furniture (meaning poly stock and forearm). I am selling for 725.00 $$ or best reasonable offer. To contact me direct use email: firstname.lastname@example.org or phone 208-827-2113 The CETME rifle was designed primarily by the German engineer Ludwig Vorgrimler, who based his design on the experimental German StG 45(M) and the French-made AME 49. The StG45 used a roller-delayed blowback mechanism somewhat similar to the roller-locking system patented by Edward Stecke in the 1930s in Poland and used in the MG 42. The MG42 locking system actually locks completely and requires a short stroke barrel that travels backwards to unlock, compared to the StG45(M) system that never completely locks and does not require a moving barrel. The CETME design inherits the StG45(M)'s fixed-barrel. The first prototype rifles fired the same 7.92×33mm Kurz round as the StG45, and a variety of experimental 7.92 and 7.62mm cartridges were tested before settling on the 7.62×51mm CETME. This round was dimensionally identical to 7.62×51mm NATO, but with a lighter bullet and powder charge to reduce recoil, making fully automatic fire more controllable. Due to feedback from Heckler & Koch, the production rifle was chambered for the more powerful 7.62mm NATO. The Model B went on to be the foundation of the widely-deployed Heckler & Koch G3 battle rifle.
