Miss Feeding Problem

[Pete360]

Hi, What causes miss feeds? ie my M4 works ok on full auto but not on semi? It will Fire about 4-5 bbs after about 5 pulls on the trigger. Thanks

are you using new mags/different bbs? have you tried firing it with hop completely off have you cleaned the barrel? Also what make is it.

I'm guessing that Specna Arms B06 (I know, M16, but same thing internally)

 

Could be any number of things.  Hop rubber lips protruding too far, a worn tappet plate, a slightly miscast hop unit, a gypsy curse.

 

If in doubt, pull the barrel and re-seat it in the hop, and check if BBs will drop down the feed tube without sticking before re-assembly.

 

Something else I've have luck with is popping a 6mm drill bit up the feed tube and verrrry carefully creating a tiny indent in the top of the chamber.  We're talking light pressure and a few turns, or even go in reverse: you're just creating the slightest of concave shapes to give the BB something to key into.
