Availability: Out of stock

GPI/IMI M4 Carbine
The roots of the GPI-IMI rifles can be traced back to Israel, a land whose history is steeped in conflict and invasions. Having fought on the front lines in the war against terrorism decades before the United States, the Israeli's are very particular about their security and choice of weapons. The GMI-IMI rifles bring together the best of Israeli and American design and manufacturing, with features and performance rarely found in this price range.

Match Grade 16” Barrel
This barrel is cut from 4150 CMV steel into a M4 contour and chambered in 5.56 with a 1/8 twist rate, then finally given a matte black Nitride Finish. The 4150 CMV (Chrome-Moly-Vanadium) Steel is considered the standard for producing mil-spec barrels due to its increased carbon content and addition of Vanadium. These additions grant the barrel greater resistance to the high temperature stress caused by burst and automatic fire.

M16 Bolt carrier group
This rifle comes standard with a true mil-spec M16 Bolt carrier group and solid stainless firing pin. The BCG has been coated with a Black Nitride Finish that is far superior to phosphate or hardened chrome treatments. Salt Bath Nitriding offers greater wear and corrosion resistance while also providing a lower coefficient of friction. It also alters the surface of the metal to counter any dimensional build up where as hard chrome coats the surface of the metal potentially causing “fit and function” issues.

GPI Forged Lower and Upper Receivers
GPI Lower and Upper Receivers are precision machined from 7075 aluminum alloy then T3 anodized.
7075 Aluminum is the preferred material for moving mechanism housing due to its high wear resistance. 7075 Aluminum is also more resistant to bending and flexing than 6061 Aluminum which some other receivers are machined from. The T3 anodizing forms a very hard coating of aluminum oxide that penetrates the surface of the base aluminum alloy. This coating adds superior abrasion, wear, and corrosion resistance as well as giving the metal a high operating temperature. The flat-top upper provides the ideal mounting platform for state of the art optics.

Gas Nitride Process
Gas Nitriding excels where Chrome Lining, the previous standard in barrel coating, often fails. The Salt Bath Nitride process gives the bore and exterior of the barrel a superior resistance to wear and corrosion while increasing the metals lubricity. It allows the barrel to take much more abuse without any loss of accuracy. As previously stated regarding the bolt carrier group, hard chrome, when added to the surface of the metal, causes inconsistencies in the bore which can greatly affect the rifles performance. This concern is negated with the Nitride process due to its alteration of the existing surface.
