well as i never really got any solution to issue, nor a huge amount of support, finally went my own direction and fingered it out, of course with the help of ynotaz, and delta6, and since it was a few months since we kinda fingered the issue, wasn't until today that the resolution arrived.
so we figured out the flash hider and or the barrel was threaded incorrectly and created a shaved pc of bullet on exiting, took a bit to finger it, but with three bozos ruminating on it, the idea came to the top.
so immediately after we considered this issue, i ordered a new hider, birdcage type, and threw it on the unit, and since desert was closed to shootin, it was not till today it was or is resolved. Am so glad as i had purchased this to essentially be a suppressor host, and after finding it couldn't hit crapola consistantly well, was determined to get it resolved or send it back which almost happened.
so today, ran maybe 80 rounds thru it and with the Sparc red dot , it nailed it so. KEEPER .
happy tuesday
