Here she is, took a shooting positions class yesterday and put prob 80 rds down range before she dried up and the bolt was gunked up.  I cleaned and lubed her real good prior to shooting.  Obviously when I'm shooting with the can on, rds are ejecting at 1:30-2:00, inside looks like shit rds in the magazine are black.  When the can is off she shoots perfect!!!  

It's a 11.5 spikes light weight barrel, bcm auto bcg, h2 buffer, urx ii

How can I fit some type of adjustable gas block somewhere with the urx ii, I'm thing of the war upper receiver that has the adjustable gas port on the reciever.   I've already spent so much on this build and took forever.

Why dont you try a Wolff XP buffer spring?  That tamed my gun a lot with the can on.  It's certainly cheaper than an adjustable gas system.

At a minimum, get an H3 buffer.  H2 is optimal for a standard length carbine with NO can.

An adjustable block may not be necessary if the H3 works... but ideally you'd like to trim some of that gas flow into the BCG.

Also... switch to FROGLUBE... that stuff sticks around longer than a pertroleum lube.

Try the micromoa adjutale gas block, mine fits under the very tight noveske/sws rails.

I love my WAR upper.  It works incredibly well on my suppressed 11.5.

I like the micromoa but my barrel is .625 and the micro moa only comes in .750.  I like the war upper because its a turn of the switch.  Is it night and day when shooting suppressed?
