R-KivE Posted February 10, 2009 Report Share Posted February 10, 2009 Hey guys, My m4a1 is shooting lower than it should be, I have dropped the rear sight as low as possible. Is the front sight adjustable? Link to post Share on other sites
lighthelamp Posted February 10, 2009 Report Share Posted February 10, 2009 Dumb question but have u tried adjusting the hop up? What weight bb are you using? And maybe you have bad compression if you opened up the gearbox then check for compression issues. Link to post Share on other sites
L4byr1nth Posted February 10, 2009 Report Share Posted February 10, 2009 Check the HOP Up is adjusted correctly FIRST, and the weight of the BB's you're using. Then start looking at compression issues, as above. Ben. Link to post Share on other sites
R-KivE Posted February 10, 2009 Author Report Share Posted February 10, 2009 right the gun is actually shooting too high my mistake. have turned the hop up off all the way and it is shooting a fair few inches above my red-dot sight. I have adjusted the red dot too as high a position as possible. when I play with the hop up and have it near the fully on area the gun shoots extremely high, its as if the bbs just fly upwards! is this normal?

ardrummer292 Posted February 10, 2009 Report Share Posted February 10, 2009 1. What weight of bb are you using? 2. Punctuation, FFS. Link to post Share on other sites
gisburn20 Posted February 10, 2009 Report Share Posted February 10, 2009 Hi , I has a JG M4 and the hop was very high out of the box ,even on 0.28's it was a bit high. (with the hop all the way off) try stripping it down and refitting the hop rubber , ( and clean the barrel properly , JG guns have filthy dirty barrels) other than that , run a few hundred rounds through it , see if it settles down. I was dropping a one piece hop in mine anyway, so I ended up binning the old unit entirely. Jim Link to post Share on other sites
Danke Posted February 10, 2009 Report Share Posted February 10, 2009 What distance are you sighting in at? 60-100 feet, or across a typical room? Link to post Share on other sites
