G&P M4A1 RIS Help
 

I need to remove one last pice of this unknown ris unit. my hopup is currently on a angle and i cant seem to twist the outer barrel. Any one have a idea on how i can finish the job and get this barrel to twist?

Gotta buy an armorer's wrench to take that nut off

put the pins back in and thread the RIS back on...then twist the entire ris off.

which way is it supposed to turn?

I don't remember off the top of my head if it was the old, righty tighty lefty loosey thing our not :)

When mine first got stock, it was completely apart like your photo. I put a vert grip on one side of the RIS and one on the other..(2) and then put the upper body between my legs...I hardly had to put any pressure on it with that set up and the entire RIS and Delta ring part let loose from the body. Then you just unscrew the RIS from the delta etc once its all apart.

Taking it off has been counter clockwise everytime I've done it.
