Has any one installed a tight bore on M4 models? I would like to know if any one can walk me through it. From the instructions i know how to separate the gun into the two main parts but from there i am not sure. I did some Googling, Youtubing and found a cool sight Mechbox.com but did not find exactly what i was looking for. Thanks in advance :D .

this should be it

Thanks dude this is exactly what i am looking for. But to get the hop up unit off does it just pull out? Any one know? Thanks again!

Take the little clip that locks the inner in-place off from the front of the unit and pull the inner + sleeve out.
