WETTI M4 Upgrade to OpenBolt or replace broken Floating Valve ?
Hi,
today my WETTI M4 have broke ... all the gas where released in one big smelly cloud and the gun did not fire ( tested with more that one mag ). As a read it may be the Floating Valve that just broke, seem to be that, causse when I pull the bolt back, the floatting valve stay at is place and don't go back. Here is a picture with the bolt pull back ( floatting valve stuck at is place ) ! But the other problem is that the bolt don't want to go at is place correctly and I can't separate the lower receiver from the uppper of my M4. I have remove the stock and the bolt don't go at his place ... Anybody have a solution for this ? Gun Doc avaiable near Trois-Rivières, Québec ?

You may have some broken BB's built up in the hop up, my closed bolt M4 jammed just like yours a few times due to this. Try working the bolt free by pulling the charging handle back as far as it will go. Then take the BCG out and check for an obstructed barrel.

Thanks to a PV from Kos-Mos yesterday nignt I have remove my outerbarrel and delta ring and it let me push the barrel/hop-up foward and then the bolt also.
The floatting valve is really broke ! What is the best think to do ... replace the floatting valve with a new npas assembly ? Upgrade my WETTI to an Open Bolt Kit ?
