300 AAC blackout problem
Posted: Wed Feb 08, 2012 1:50 am
I'm having problems with my new 300 Blackout on my PWA Preban lower.
Fires fine but won't load a new bullet after it ejects the old one, just cycles the bolt forward with no bullet in the chamber.
I am using 220 grain Remington Subsonic Factory loads without a silencer on it, (going to wait for the SR7 and 90T mount) but in the mean time I like the quieter Subsonic loads.
From what I can find out on the web the problem is the unsuppressed rifle with the subsonic load not having enough pressure to cycle correctly, is this correct or should I be looking at another possible problem ?
I bought the rifle from the local gunsmith already assembled so I'm not sure what buffer or gas port set up is on the gun, is there a correct setup I should be using to fire the unsuppressed sub loads that I can tell the gunsmith to use ?
And if I change anything now will that create a problem later when I finally do put a suppressor on it ?
Any help would be appreciated
Thanks
