A bad o-ring in the asa will cause a leak out of the asa, not down the barrel.
You are correct.. But for some strange reason thou different asa on the gun it worked perfectly no bad o rings on the bolt or anything. I changed the #007 o ring in the bad proto asa and it works with the gun now so must be one of those rare things
