located underneath the bolt carrier. All the French MAS 7.5mm semi-automatic rifles mentioned herein feature a rear-locking tilting bolt, as on the M1895 Colt–Browning machine gun, the Browning Automatic Rifle (1918), the MAS-1924 to MAS-1928 experimental semi-auto rifles, and the Russian Simonov SVT-38 (1938) and SVT-40 (1940) rifles. The MAS direct impingement design reduced the number of bolt moving parts to only six: the bolt carrier, then the rear locking tilting bolt which carries the extractor, the ejector and the firing pin, and lastly the recoil spring. It takes only a few seconds to disassemble the entire bolt mechanism for cleaning. The same 10-round detachable magazine fits the MAS-44, MAS-49 and MAS-49/56 rifles. The earlier MAS-40 (1940) rifle had a 5-round magazine within the receiver, as on the bolt action MAS-36 rifle. The rifle can still be fed by stripper clips, and have a stripper clip guide built into the bolt face. Lastly, the MAS-49 and MAS-49/56 are equipped with a rail on the left side of the receiver. It allows for the immediate installation of a "Modele 1953" APX L 806 (SOM) 3.85 power telescopic sight by sliding it into place and then locking it in with a small pressure lever. The MAS-49 and MAS-49/56 are capable of consistently hitting individual man-size targets up to 400 meters with the adjustable peep sight and up to 800 meters with the APX L 806 telescopic sight. The bore is counter sunk at the muzzle to protect the rifling and preserve accuracy. The barrel is freely floating. Syrian Contract Rifles Syria contracted with MAS for 6,000 MAS-49 rifles. These rifles, along with 12,000 MAS-36 rifles and a production facility for 7.5x54mm ammunition were delivered in the early 1950s. The MAS-49 was used until the mid-late 60s when they were replaced with AK-47 assault rifles. Syrian contract rifles differed from the French service model by having a spike bayonet identical to that of the MAS-36, as well as different stocks and metal parts to incorporate this change. These rifles are dated 1953 and features serial numbers in the F33.000 to F39.000 range. Surplus imports to the US Many MAS-49/56 rifles imported as surplus into the United States were rechambered locally by Century Arms International to fire the 7.62mm NATO round. However several user reports have noted that these particular conversions were often unsatisfactory (resulting in numerous action stoppages and misfires) due to imperfect
