Turkish defense manufacturer MKEK (Makina ve Kimya Endüstrisi Kurumu) began development of a new assault rifle for Turkish armed forces in around 2007.  By 2008, MKEK produced a 5.56mm rifle called Mehmetçik-1, based on German HK 416 rifle. After several years of tests and development, Turkish army re-evaluated its requirements, and, based on its actual combat experience with various calibers in service (7.62×51 in HK G3, 7.62×39 in Kalashnikov AKM and 5.56×45 in HK 33), decided to stay with 7.62×51 NATO round for its next army rifle.
As a result, in May 2014 MKEK delivered first batch of 7.62x51mm MKEK MPT-76 automatic rifles to Turkish army. “MPT” stands for Milli Piyade Tüfeği, or National Infantry Rifle in English. MKEK MPT-76 rifle appears to be visually and technically similar to German HK 417 rifle. Fate the 5.56mm Mehmetçik-1 rifle is uncertain at this point (May, 2014).

MKEK MPT-76 rifle is gas operated, select-fire weapon. It uses short stroke gas piston, located above the barrel, and AR-10/Ar-15 style rotary bolt, bolt carrier and return spring system. Aluminum alloy receiver also is based on AR-10/AR-15 design, with upper and lower halves being connected by two captive cross-pins. Rifle features M16-style charging handle, ambidextrous magazine release, bolt hold-open release and safety / fire selector controls. Ammunition is fed from 20-round box magazines, made from translucent polymer. Rifle is equipped with telescoping, adjustable shoulder stock. Front sight is mounted on the gas block and features folding base. Integral Picatinny rail on top of the receiver can hosts aperture-type rear sight (fully adjustable for range and windage), as well as quick-detachable carrying handle with “see-through” channel for standard iron sights plus its own set of iron sights for short-range applications (with U-shaped notch rear sight), built into the top of the handle.  Carrying handle can be easily replaced with any type of red-dot, telescope or night sight with appropriate mountings. Additional Picatinny rails on the forend permit mounting of various accessories. Knife-bayonet may be attached for the barrel, if required.

The Mod. L rifle had been developed by Spanish CETME company (now Santa Barbara SA) as a further derivative of the previous Mod. 58 ad Mod. B rifles. These rifles, in turn, have their roots in WW2 German assault rifle Stg.45, developed by Mauser. After the WW2, some Mauser men moved to the Spain and started to work for CETME, where they developed the Mod. B battle rifle, chambered for 7.62mm NATO cartridge. This rifle later was licensed by Heckler&Koch and beбame the famous G3, but CETME also continued the development. In the mid-1960s men at CETME began to work at smaller-caliber version of the basic rifle, initially called Mod. E. Development was completed in 1980, when first prototype of the Mod. L, chambered for 5.56mm cartridge appeared. Production of the Assault Rifle Mod. Land carbine Mod. LC began in 1984, and it was adopted by Spanish army. In 1999 this rifle was declared obsolete by adoption of the H&K G36E assault rifle.

Like the previus models, CETME Mod. L is a delayed blowback operated, selective fire assault rifle. It has two-piece bolt with two rollers, which are used to accelerate bolt body and to slow bolt head and to hold the cartridge case in chamber until the pressure will drop. The chamber walls are fluted to help the extraction. Overall design is somewhat similar to H&K 33 rifles, but Mod. L is easily distinguishable by larger triggerguard and different (from HK designs) plastic pistol grip and handguards. Sights on Mod. L also are different from HK pattern and rear sight is a simple flip-up “L” shaped leaf with two apertures for 200 and 400 meters. Magazine port also is different from HK pattern and is designed to acceptt M16-type magazines. Carbine Mod. LC differs from the Mod. L by having shorter barrel and telescoping metallic buttstock.

Cristobal Model 2 Cristobal Model 1962
Caliber .30 M1 US Carbine (7.62×33 M1)
Action Delayed blowback

The Cristobal Model 2 assault rifle / carbine is an interesting weapon which is somehow not easy to classify properly. Technically, it is close to typical submachine guns, as it fires from open bolt, but it’s cartridge is way too powerful to be considered as a “pistol” round, as the .30 US Carbine develops about 1300 Joules of muzzle energy and thus is about 2-3 times more powerful than a typical military pistol round like 7.62×25 TT, 9mm Luger or .45 ACP, and has maximum effective range of 300-400 meters.
The Cristobal Model 2 assault rifle / carbine was developed by famous Hungarian small arms designer Pal Kiraly, who after the WW2 left Hungary and settled in the Dominical republic. The Cristobal Model 2 assault rifle / carbine is broadly based on two submachine gun designs – internally it resembles the Hungarian 39M submachine gun (designed by Kiraly), and externally it somehow resembles Italian Beretta M1938, which at the time of M2 development was manufactured under license in Dominicana. Production of the Cristobal Model 2 assault rifle / carbine began in mid-1950s, and it was produced in significant numbers. In 1962, a modified version, known as Cristobal M1962, was designed and entered production. The Cristobal Model 1962 assault rifle / carbine was slightly shorter but heavier than its predecessor. It was also manufactured with fixed wood stock or with side-folding wire stock.
The Cristobal Model 2 assault rifle / carbine is a delayed blowback weapon that fires from open bolt. In this system, bolt consists of two parts, with pivoting lever attached to the forward part (bolt head). When in battery, the bottom hand of the lever is resting against the receiver, and the upper rests against the rear part of the bolt (bolt body). Upon discharge, movement of the bolt head forces the lever to rotate back, thus speeding up the bolt body and slowing down the initial opening of the bolt head. Once the lever is fully pivoted, both parts of the bolt can recoil together freely against the return spring, to complete the firing and reloading cycle. Firing is from open bolt, in full automatic mode or single shots. To select mode of fire, weapon is provided with two triggers – front trigger delivers single shots and the rear trigger delivers full automatic fire. The manual safety lever is located on the left side of the receiver, below the rear sight. Feed is from detachable box magazines with 30-round capacity. Standard stock is made from wood. On Model 2 rifles, the rear sight is adjustable for range from 100 to 500 meters, the Model 1962 has a simplified L-shaped flip-up rear sight.
