But I found AS BBU using SD o-ring with SD nozzle is way too tight and it make the nozzle can't go back to rest position when cycle.
Not sure is it because lack of silicone oil for the o-ring.
Mr. Hit man is right. I think Brian also suggest in his retailer thread that AS 140% is stronger than 150% on the market. It should be used and fine tune by gun smith.
