Tucson Arizona based GG&G has been setting the quality and performance standard in AR 15 accessories for over 13 years. During that time countless civilian, law enforcement and military shooters worldwide have used the innovative AR 15 parts and AR-15 accessories manufactured by GG&G. Given the nearly identical nature of the M-16 and its shorter cousin the M4 rifle, these AR15 accessories are a natural fit for those rifles as well, and many M16 accessories manufactured by us are trusted by soldiers in extreme combat environments. Over 50 of the 132 tactical components we manufacture are specifically mounting accessories for the AR15. All of these mounting accessories are manufactured from solid billet aluminum or steel and are plated to meet military specifications. As with all GG&G high performance tactical products, the GG&G AR-15 parts and accessories are manufactured to withstand the rigors of combat. AR-15 tactical accessories come with a lifetime warranty that simply says if it fails, we will repair or replace it.
