    its pretty difficult, I have an Echo 1 M16A4 and removed the front sight to add a solid gas block and upgraded it into an SR25, my fps runs about 750fps

    I would have to see the Chrono to believe that FPS value, but it sounds epic.

    all you have to do is remove the barrel to put a new front sight on you dont have to pull off the flash hider but if you dont want to pull the barrel off look for a small hex wrench and put it in the screw on the bottom of the flash hider

    Echo 1 adds a drop of super glue to the hex heads...you have to put the outer barrel extension into HOT water for about 5 min. then put a rag around the flash hider and use a pair of vice grips to get the flash hider off
