The CETME rifle, caliber x 51 mm., is a weapon developed using the most modern fabrication methods. It may be fired a round at a time with automatic loading, or fired automatically. Its functioning system is mass recoil with semi-rigid locking and a fixed barrel. It has a flash suppresser screwed on to the mouth of the barrel which permits rifle grenades to be fired with no other device required. The feeding is accomplished with a magazine of 20 cartridges. 5 cartridge magazines have also been fabricated, and are useful for instruction, and garrison duty.

3 In its normal version it is provided with a wood handguard, (fig. 1), but it also can be fitted with a metal handguard and a folding bipod (fig. 2). The weapon equipped with a wooden handguard can also have a telescoping bipod fixed to it when needed (fig. 2 a). In the interior of the cocking rod guide tube, a cleaning kit can be found. A knife-bayonet (fig. 3) can also be fitted to the weapon. Optical (fig. 4) or infrared sights can also be mounted. By substituting the flash suppresser with a special adapter, blanks can also be fired. A simple and easy to use magazine speed loader can also be provided with the weapon. file:///C|/WINDOWS/Desktop/version 2 [3/23/2002 8:39:37 PM]. 4. file:///C|/WINDOWS/Desktop/version 2 [3/23/2002 8:40:33 PM]. 5. file:///C|/WINDOWS/Desktop/version 2 [3/23/2002 8:41:36 PM].

The barrel is fixed, at its rear portion, to the trunion block. At its fore end it has a threaded flash suppresser. The receiver is fabricated from a sheet metal stamping. At its fore end it is joined, by welding, to the trunion block.

5 At the rear it is joined to the buttstock by two crosspins. On its lower section it has the magazine well, and to this part the grip assembly is joined by a crosspin. The cocking mechanism is situated on top of the barrel. The cocking handle folds;. it serves to cock and feed the weapon and also permits locking the firing block in its retarded position via a slot cut into the end of the guide tube provided for this purpose. The sighting mechanism consists of a front point sight and an adjustable rear sight with four positions: one with a rapid acquisition blade for distances up to 100 m. And three of a <<diopter>> type for firing from 100 to 200 m., 300 m. and 400 m. The wooden handguard is provided, at both of it's ends, with metallic reinforcements to provide attachment points to the weapon. The rear extreme fits into a circular groove on the trunion, and the forward extreme is held via a clamp that encircles the barrel and a screw that locks it in position.

The metal handguard, that is only used on weapons that carry a foldable bipod (fig. 2) is held at it's rear extreme in the same way as the wooden handguard; at it's forward extreme it is held on the barrel via a spring clamp that is riveted to the handguard. The bipod is held on the barrel via a clamp and both legs have a device that allows the rapid movement from one position to the other (unfolded or folded). When the bipod legs are folded, they reinforce the clamping of the metal handguard to the barrel. The bipod model BR is installed directly to the weapon at the front sight mount, needing only to close the legs to open the clamp. The bipods legs can be shortened or lengthened telescopically. The flash suppresser permits, with no additional parts added to the weapon, the launching of normalized NATO rifle grenades.

It's mission is to feed, lock, and extract the case after it is fired. It consists of the following parts: Bolt carrier with recoil spring support tube. Bolt head with locking roller, extractor, and extractor spring. Firing pin holder. Firing pin spring. Firing pin. file:///C|/WINDOWS/Desktop/version 2 [3/23/2002 8:45:19 PM]. 10. file:///C|/WINDOWS/Desktop/version 2 [3/23/2002 8:46:13 PM]. 11. 3. Grip with trigger mechanism (fig. 7). The grip is joined at its front end to the receiver via a crosspin that serves as its rotation point. At the rear end it is held between the receiver and the buttstock holder.

8 The grip holds in its upper part the trigger mechanism, that is comprised of the following principal parts: Trigger. Disconnector assembly. Hammer. Safety lever. Ejector. These parts, with their crosspins and corresponding springs, are mounted in the trigger pack (b). The grip and trigger pack are held together by the shaft of the safety (c). file:///C|/WINDOWS/Desktop/version 2 [3/23/2002 8:47:16 PM]. 12. file:///C|/WINDOWS/Desktop/version 2 [3/23/2002 8:48:10 PM]. 13. 4. Buttstock assembly with recoil spring and buffer. (fig. 8). The buttstock is made of tropical walnut, ("nogal"). It has a pad of hardened rubber, with metal reinforcement. At the front end of the buttstock assembly is the buttstock housing, which is held to the grip assembly via two crosspins. The recoil spring support tube is riveted to the buttstock housing.

9 The end of the recoil spring is retained by a bushing that is held at the end of the tube by a crosspin. The union of the buttstock housing with the buttstock is accomplished by the recoil buffer support that, via a screw, is fixed to the buttstock housing. The recoil buffer consists of three hardened rubber disks. file:///C|/WINDOWS/Desktop/version 2 [3/23/2002 8:49:08 PM]. 14. file:///C|/WINDOWS/Desktop/version 2 [3/23/2002 8:49:56 PM]. 15. DESCRIPTION OF THE ACCESSORIES. 1. Magazine. Is made of stamped sheetmetal. Two types are fabricated: the normal, with a capacity of 20 cartridges, and another of 5 cartridges for garrison duty. 2. Sling. Is made of web material, with a clip at one of its extremes and a buckle that permits regulation of its length. 3. Blank firing adapter. It is used in substitution of the flash suppresser.

10 It can be regulated, to allow firing blank cartridges of different strengths. 4. Cleaning Kit. It is stored in the forward end of the cocking rod guide tube and is held in place by the cap of the knife-bayonet lug. Contains: a bore brush, an articulating bore rod, held to the cap with hemp string, and four capsules of oil. 5. Muzzle cap and protective cover. The muzzle cap is plastic. It blocks the passage of dirt into the interior of the barrel, and even though it should be removed before firing, if that detail is forgotten no danger exists. The cover is used to maintain the weapon in service ready condition when it must be stored for long periods of time. file:///C|/WINDOWS/Desktop/version 2 [3/23/2002 8:51:27 PM]. 16. file:///C|/WINDOWS/Desktop/version 2 [3/23/2002 8:52:18 PM]. 17. 6.
