"Okay i dont like how you cant get a different size like shorter or longer, and in the picture it shows a spring on the hop up nub mine did not come with a spring its okay because i had an extra one luckily but should have came with one. Other than that the stock a&k hop up is okay for a replacement to last you a little while but just keep in mind when buying this part that it does NOT come with spring like in picture. And the brass barrel it comes with is cheasy but you get what you paid for cant complain really just cant beleive it shows a spring in the picture.
