same guns but the matco ones have a longer warranty. its just if u wanna pay for the warranty. apparently theres a piece in the trigger thats supposed to go out around when the IR warranty goes out but i havent had a problem with mine yet. i got the matco 3/8 and 1/2 ones bc my matco guy price matched them for me they kick ass though!!! i honetly wouldnt get a 1/2 impact with less than like 600 ft/lbs. i think mine does 700 max or so and i still have trouble with some stuff sometimes. just bc it says it can do 200 ftlbs doesnt mean that u actually get a useable 200 from it. plus cheap air tools suck. cheap tools suck period in my opinion but i beat the shit out of mine daily so good tools are a must
