In this episode I’m going to be reviewing the "Troy Industries A4 Other" firearm and my upgrades. This firearm is legal in "New Jersey" and from my understanding may be legal in Connecticut also, but not New York. Because I am not a lawyer, I recommend you the check CT/NY State law. Every aspect of the TROY A4 “other firearm” was built from years of experience working with military and law enforcement agencies around the world. The result is a powerful, compact, and lightweight firearm that fills the niche between AR-15 Rifles, SBR and AR Pistol platforms. It's a great firearm and after putting thousands of rounds down range, it's still rock solid with nothing that needs tightening.
