All 7.62mm CETME rifles are built around Vorgrimlers' roller delayed blowback system.
All those weapons are built using the delayed blowback system of operation, designed by Vorgrimler and his men at the Mauser in 1945 and refined by CETME.
It utilizes a locking roller to delay the blowback action of the bolt carrier until the pressure in the barrel is reduced to a point

 CZ27 and CZ52 pistols
CZ52 was an unusual design utilizing the same roller-delayed blowback action as the MG42, G3 and MP5.
CZ27 was a simple, if well-produced, 7.65mm (.32acp) blowback pistol designed in 1927.
It was typical of the German army to press captured arms and arms production facilities into use to alleviate its chronic shortage of weapons.

The roller-delayed blowback mechanism keeps recoil to a manageable level, but the muzzle blast and report is substantial.
Other significant changes in the AK-102 include a redesigned action, modified blowback system, and an offset magazine.

 Modern Firearms - Heckler-Koch Ultimate Combat Pistol / HK UCP
The action of the gun is said to use some sort of retarded (or delayed) blowback system, but so far it is not known, if it is a roller-delayed blowback, as in HK P9s pistol, or a gas-delayed blowback, as in HK P7 pistol.
The development of UCP has been started on request from Bundeswehr (German Armed forces) in 2002 or 2003, and this pistol is intended to become a companion to HK MP7 Personal Defence Weapon, which is also is under serious consideration for Bundeswehr, as well as some counter-terrorism forces in Germany and abroad.
Like the Five-seveN pistol, the UCP is intended to provide accurate pistol fire, with high armor piercing capabilities, high accuracy, large magazine capacity and low recoil.

 Heckler & Koch - Tactical Weapons - H&K - G3 - HK53- Rifles
The G3 rifle was the first HK firearm developed using the delayed blowback roller-locked operation common to most current Heckler and Koch submachine guns, rifles, and machine guns.
Using the robust and reliable delayed blowback roller-locked bolt operating system first developed by HK engineers for the G3 automatic rifle, Heckler and Koch has created a variety of weapons designed to meet any tactical need.
Heckler and Koch rifles and carbines are recognized as the most technologically and tactically advanced weapons in the world.

Roller-delayed blowback is not to be confused with the older roller-locked recoil operated principle, as used in the MG-42 and MG3, where the bolt is rigidly locked to the barrel as it recoils.
Gas-delayed blowback is one of the rarer operating principles.
It was recoil operated, and the cylinder and barrel recoiled backwards to cock the hammer and revolve the cylinder.

 Expedition Exchange Bulletin Boards - 9mm vs.45
The FAL (relatively high bore axis with pistol grip and gas operation), G3 (straight-line construction with pistol grip and roller-delayed blowback operation), StG57 (straight-line construction pistol grip and roller-delayed blowback operation), and M14 (relatively high bore axis with rifle stock and gas operation), for example, are all uncontrollable in full-auto mode.
On measuring the bore axis on pistols, I think the more correct way to measure the bore axis is not from the trigger to bore axis, but rather from the top of the web of the hand to the bore axis.
Gaston Glock thoughtfully lowered the bore axis on his design as much as he could, just as HK lowered the bore axis on the P7 as much as it could.

 Heckler & Koch - Wikipedia, the free encyclopedia
In its extensive product range, HK has used most of the operating systems for small-arms: blowback, short recoil, roller-delayed blowback, gas-delayed blowback, and gas-operated.
HK was founded by Edmund Heckler, Theodor Koch, and Alex Seidel in 1949 from the remnants of Mauser, and the company was registered in 1950.
HK has been contracted by the US Army to produce the kinetic energy subsystem of the Objective Individual Combat Weapon, a planned replacement for the M-16/M203 grenade launcher combination.

 TheFiringLine Forums - James Bond's gun maker set to buy Heckler & Koch
Pre-sale: P7, P9, VP70, MP5, G3, G11, roller-delayed blowback, gas-delayed blowback, squeeze-cocking, machinepistols with detachable shoulder stocks, caseless ammo.
I thought the VP70 was pretty cool, until I got the chance to dry-fire one at a gunshow.
I thought it looked like a cool, futuristic pistol, and only later discovered that it was a product of the late 60s.

 Modern Firearms - Heckler Koch G3 assault rifle
The roller-delayed blowback action is described under the CETME Rifles, so I will not repeat it here.
The G3 rifle is a selective fire, magazine fed rifle, built using delayed blowback action, developed by German engineers at Mauser Werke late in the 2nd World War and refined in Spain, at the CETME company.
Every G3 rifle can be equipped with detachable bipods, claw-type detachable scope mounts.

The G3 rifle is a selective fire, magazine fed rifle, built using delayed blowback action, developed by German engineers at Mauser Werke late in the 2nd World War and refined in Spain, at the CETME company.
Initial models of the G3 rifle were quite similar to CETME rifles, and even had "CETME" markings on the receivers (until 1961 or so).

The recoil when firing a gun is the backward momentum of a gun, which is equal to the forward momentum of the bullet or shell, due to conservation of momentum.

 HK MSG90
Like most of HK's rifles and submachine guns, it uses the robust and reliable delayed blowback roller-locked bolt operating system that has a well-earned reputation for delivering amazing accuracy and reliable performance.
The MSG90's forend is fitted with an Ashchutz T-way that will accept one of HK's newer adjustable bipods.
Special brackets integral with the MSG90's receiver accept a quick-detach STANAG-based scope mount; this mount is compatible with all NATO-standard optics and ensures 100% zero retention even after repeated mountings.

What turns the tide on this automatic machine gun is the unique roller-delayed blowback system, which operates the weapon in a fully locked breach position.
The MP5 is used various purposes in the Teams, but mostly for Close Quarters Combat.
Where other auto systems rely on the weight and velocity of the returning breach to seal the chamber the MP5 uses a series of locks and cams to seal off the chamber.

Like most of HK's rifles and submachine guns, it uses the robust and reliable delayed blowback roller-locked bolt operating system that has a well-earned reputation for delivering amazing accuracy and reliable performance.
Even a fully-automatic G3 or 21E can be fitted with quality optics, but battle rifles and machine guns (like their users) are perhaps best confined to their intended roles.
The unit that HK offers for the MSG90 is more streamlined than the PSG1's tripod but considerably more versatile than the G3 light bipod.

Both HK 23 and HK 73 are more accurate than the M249, Negev and other machineguns in the same caliber.
