300 blkout subsonic cycling issue - FOUND THE PROBLEM
« on: April 19, 2013, 05:08:55 AM »
The barrel was installed rotated a few degrees off-center.  The lo pro gas block was installed plumb so there was an offset between the GB and gas port.  Loosened the GB and rotated slightly to my alignment mark and subsonic cycling issues are gone.  Now to buy the tools and fixture to install the the barrel correctly to the upper, oh and and a new buffer spring.   I am not gonna post where I got the upper but if you want to know, send me a PM.
 
thanks,

Why be difficult, when with a little extra effort you can be impossible?

If you have to buy the wrench be sure to check how it fits on the bbl nut some work from the lefty others from the right. or when in use the open side will either be on top or under the bbl. Mine is under ( didn't think to check. ) and it feels awkward . I have seen several that fit the other way . After using one of the other wrenches I like it better feels more secure.
If ya can see it ya can hit it !
