WE M4 GBBR Mag Dump Issue
 

SO!
My WE M4 GBBR was fine n dandy with the open bolt setup and the stock nozzle. Well the nozzle broke and didnt use the thing for a while. Now i have a Ra-tech aluminum nozzle with npas. Here is the problem now

metal open bolt plus the ra-tech nozzle is causing my rifle to get stuck open and dump the mags
When i fire no bb's come out and i can see the nozzle is kinda stuck in the barrle and wont pull back with the bolt. Iv cleaned and lubed it and that didnt fix. Havnt changed anything els other then removed the bolt, replaced the nozzle and now this. Have changed the NPAS setting too and no change.

Ideas?
Mags are fine they all work in my WE open bolt scar. I dont think the scar takes the same nozzle or id swap it in that and see what happens

Friend of mine recently bought the full ratech bolt and discovered that the nozzle didnt move freely. I think he said it took a bit of filing to make it work right.

Oh damn!
If you could be so kind.. see what places he had to trim down a bit :)

1 of 2 problems may have occured. the "striker" or loading arm as they call it is sitting too low.

the other problem may be the NPAS is fully closed and is not allowing air to the BB cuasing the air to be routed to the blowback.

I just asked, apparently I misunderstood, and the filing he had to do was on the bolt itself, where the bolt catch grabs it.. My bad, sorry.

That said, on my we g36 when I got a new (plastic) nozzle I had to file the guides for the runners a bit, maybe check there and see if there's any binding going on?
