The IWI ACE (formerly IMI Galil ACE) is a family of rifles developed and originally manufactured by an Israeli firearm manufacturer, Israel Military Industries (IMI) of Ramat HaSharon, though it is now produced by Israel Weapon Industries (IWI) (IMI privatized their small arms division, called IWI), and also produced under license by Indumil,[1] FAMAE,[2] RPC Fort[3] and Z111 Factory.[4] It is produced in three different calibers; 5.56×45mm NATO, 7.62×39mm and 7.62×51mm NATO.

The ACE family is based upon the mechanism of the IMI Galil, but using a modernized design and materials to increase its accuracy and lower its weight, while maintaining the Galil's ergonomics, ease of maintenance and reliability under battle conditions.[5] Emphasis was placed in particular in increasing its reliability and accuracy under adverse or battlefield conditions.

It is the main standard-issue assault rifle of the Colombian Army, Navy, Air Force and Colombian Police, the Chilean Army, and of the People's Army of Vietnam.

Design details[edit]

Weight reduction[edit]

The original Galil was built with a machined solid steel billet action in order to increase the structural integrity and survivability of the weapon. Unfortunately this resulted in a weight of up to 9.6 lb (4.4 kg), depending on its variant, which was one of the primary criticisms from the Israel Defense Forces.

The ACE has a significantly reduced weight. IWI redesigned the action to integrate the steel with polymer, which is much lighter than the fully steel receiver of the original Galil.[5] While the upper receiver is machined steel and the receiver top features a MIL-STD-1913 Picatinny rail, polymer has been introduced to the lower receiver of the weapon to reduce the gun's weight.[6]


According to American Rifleman: “Although this rifle is clearly based on the AK design, it demonstrated a superior level of accuracy potential compared to several of its cousins. The best single group of [5 rounds at 100 yards] of 0.83″ and five-group average of 0.98″ was produced using the Federal Premium 123-gr. [8.0 g] Power-Shok soft-point load” (testing done using 7.62×39mm 16-inch barrelled variant).[7]

Gas tube[edit]

The gas tube, unlike the AK-47 system, is mounted on the rifle via a dovetailed slide machined on the receiver upper-front block. This avoids any movement of the gas block influencing barrel vibration, which would degrade accuracy.[5]

Long-stroke piston system[edit]

The rifle uses the Galil's long-stroke piston system. The long-stroke system is found in the M1 Garand, AK-47 (upon which the Galil's internal mechanism design borrowed heavily) and more recently in the IWI Tavor.


The barrel is chrome-lined, cold hammer-forged, with a 1:7″ twist for 5.56×45mm NATO, 1:9.5″ for 7.62×39mm and 1:12″ for 7.62×51mm NATO.


The ACE adopts the Galil Sniper trigger instead of the original Galil trigger, in order to improve accuracy compared to the standard Galil.[8] This is a two-stage trigger,[6] which IWI have modelled on the two-stage trigger of the M1 Garand.[9]

According to American Rifleman, the two-stage trigger is “clean and smooth with a 4 lb. 13 oz. [4.8 lbf, 21.4 N] trigger pull according to a Lyman digital trigger gauge”.[7]

Last round bolt catch[edit]

Another addition by IWI to the original Galil is the last round bolt catch (for variants of the ACE in 5.56×45mm NATO only). The bolt hold-open feature is a common request of military customers, to reduce reloading times during combat.[10]


The ACE has a fully adjustable iron sights with tritium front post and two dot tritium rear aperture. It also features a Picatinny rail for mounting various optical sight.


The standard buttstock found on the ACE is a six-position telescopic stock that can be fitted with an optional cheek-piece to improve the sighting of the weapon when using an optical sight. An optional right folding version of the standard buttstock is also available.

The forearm consists of MIL-STD-1913 Picatinny rails on the bottom and both sides for mounting accessories such as aiming optics. The side forearm rails have central grooves to provide routing channels for electric wiring used by pressure switch activated accessories. The forearm comes with quick detachable polymer covering panels that can be mounted to protect the rails when a side or bottom rail has no accessories mounted to it. The gas tube above the barrel also has a Picatinny rail mounted on top that is aligned with the rail mounted on the cover over the receiver.


The ACE is available in three different calibres with multiple barrel lengths for each type.[11]

At some point,[when?] the ACE 52L was removed from the production line.[citation needed]



The Colombian Police armed with the ACE 22.
The ACE 32 used in the Vietnam People's Army.
