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 was first produced by Colombian INDUMIL, under license. Later producers under license are FAMAE, RPC Fort and Z111 Factory. 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. Emphasis was placed in particular in increasing its reliability and accuracy under adverse or battlefield conditions.
The ACE is result of the Israeli technology applied by INDUMIL during the Colombian conflict. From 2006, INDUMIL acquired license to be the sole Galil AR producer and provider in the world, even selling it to Israel. In 2010, INDUMIL presented to the world the Galil ACE family, produced in Colombia, with Colombian technology under Israeli supervision, being an improvement under license.
Initially INDUMIL, with IWI supervision and technology sharing, modified 43 out of 96 parts of the Galil AR in order to get what we know as Galil ACE. Of those 43 modified parts, 12 steel parts were replaced by plastic ones, taking out 1.0 kg, and the other 31 parts were redesigned to improve precision.
The original Galil had weighed up to 9.6 lb (4.4 kg), depending on its variant, and this weight was criticized by the Israel Defense Forces. The heavyweight was a result of IMI having built the Galil rifle from a machined all-solid steel billet action in order to increase the structural integrity and survivability of the weapon.
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. 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.
IWI has sealed the internal mechanism of the gun with the addition of a sliding vertical cover. As a result, the internal mechanism of the ACE is sealed and protected from the accumulation of dirt or sand.
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 barreled variant).
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.
Long-stroke piston systemEdit
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 ACE adopts the Galil Sniper trigger instead of the original Galil trigger, in order to improve accuracy compared to the standard Galil. This is a two-stage trigger, which IWI have modeled on the two-stage trigger of the M1 Garand.
Last round bolt catchEdit
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.
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 calibers with multiple barrel lengths for each type:
