Kaza66 Posted July 14, 2013 Share Posted July 14, 2013 When you say 'it doesn't seem to be firing' do you mean when you pull the trigger nothing happens, or when you pull the trigger it fires, but doesn't fire any BB's? Link to comment Share on other sites More sharing options...
airsoftwarrior147 Posted July 14, 2013 Author Share Posted July 14, 2013 The motor cycles bit no bbs come out. Have tried a diffrent spring and think it might be the hop Link to comment Share on other sites More sharing options...
Supporters sp00n Posted July 14, 2013 Supporters Share Posted July 14, 2013 sorry to ask a stupid question but are they hicap mags? is it not firing on both semi and auto? Link to comment Share on other sites More sharing options...
Kaza66 Posted July 14, 2013 Share Posted July 14, 2013 Turn the hop completely off- doubt it will be that though. To build on what spoon said: if you are using hi cap mag ( often standard with a gun) then you must wind them up after you have poured your BB's in at the top. The winding wheel is usually found at the bottom of the mag. Link to comment Share on other sites More sharing options...
airsoftwarrior147 Posted July 14, 2013 Author Share Posted July 14, 2013 I know there hi caps and no offence im not a noob so I know to wind the mags all the way Link to comment Share on other sites More sharing options...
Kaza66 Posted July 14, 2013 Share Posted July 14, 2013 No that's ok, no problem, but it's best to check basic things first. So from from what I can see so far: 1. Mag is filled and wound 2. Mag inserted into gun 3. Gun fired, nothing flies out the end, correct? Is there any wobble, up and down or side to side when the mag is inserted?

beermonsta Posted July 14, 2013 Share Posted July 14, 2013 Is the barrel empty? as in have you checked there is nothing stuck in it? Link to comment Share on other sites More sharing options...
geoffreym Posted July 14, 2013 Share Posted July 14, 2013 If I were to diagnose one of my ICS M4's I would (in this order): 1. split the upper and lower to make sure that the bevel gear is spinning freely (make sure that the non geared side is up once finished (you'll see what I mean)). 2. Check the piston, see whether there are any teeth missing and see whether there is any movement up down or side to side. 3. Look down the barrel from the hop side to see whether there are any obvious obstructions. 4. Re- assemble and, without the mag inserted, fire with your hand over the barrel to see whether there is any air fired out. On the assumption that there is no obvious problems from the previous check but it is still not firing try taking the piston apart as it may fix it. Personally I think it will be the O-ring seal on the piston or a tooth missing on the piston. Other than that try check the hop unit as a last resort.

RR01 Posted July 14, 2013 Share Posted July 14, 2013 The other options could be tappet plate spring bust, nozzle disconnected from tappet plate, misalignment of nozzle with hop unit, mag not seating correctly. As previously mentioned, split the upper receiver from the lower. Then try pushing in the nozzle. Is there resistance and does it spring back strongly? If so, tappet plate spring should be OK, but to test, try firing it with the upper removed. Does the nozzle move back and forward smoothly? If not, that is your problem. If it does, hold your hand in front of the nozzle as you fire it (not touching). Can you feel a strong blast of air? If so, piston seal is probably good, if not, replace seal. If all that is OK, remove the inner barrel and hop unit and push it over the nozzle until it seats properly. Now insert a partly loaded mag into the magwell. Does the mag fit properly and line up perfectly with the feed probe of the hop unit with the hop pushed hard back towards the cylinder housing, and feed bbs into the hop? If not, there's your problem. Some hop units can be a poor match for the bottom receiver. I had this with an M15 I built. One metal hop unit didn't seem to line up properly at all, but replacing it with an Element plastic hop solved the problem, whilst the metal hop worked perfectly in an M16. If all that is good, refit the upper receiver, including inner barrel, then turn over the rifle so that you can see into the magwell. Try dry firing on semi and auto. Can you see the nozzle moving smoothly back and forward in the hop feed hole? If yes, I'm stumped. If not, check the alignment of the upper & lower and that the push back spring is fitted to the top of the hop unit. Missing that out can cause a misalignment & misfeeds.

airsoftwarrior147 Posted July 15, 2013 Author Share Posted July 15, 2013 i believe its either the tappet plate, air nozzel or hop units positioning, however to contradict my other post (not noob) i dont trust myseld to brake the gun more so im going to have andy the gun tech at the grange have a look and hopefully fix Link to comment Share on other sites More sharing options...
Supporters sp00n Posted July 15, 2013 Supporters Share Posted July 15, 2013 Try looking in the mag well, down the hop bb feed tube, then dry fire the gun, it happens really quick but you should be able to see the nozzle move don't blink though it happens really really quick!

airsoftwarrior147 Posted July 15, 2013 Author Share Posted July 15, 2013 been there done that and the nozzel works fine so from what ive head the tappet plates intact but not sure will leave it to gthe techie i think also just ealised the charging handle sping snapped so thats made that useless Link to comment Share on other sites More sharing options...
