"Installed in two guns. They work. But inconsistent. Even with a steel roller bar(does not come with). However I did not super glue it to the hop arm. If you were to, it would have to be absolutely straight for it to work. The bridge will direct the B.B. as it contacts it. I have had much better consistency with the flat type or even an eraser.

"Great Quality. Beware. Dose not fit in ICS L86 hopup chambers. Dont try to use these my l85,86 buddies. Modification is required nub wise or hopup wise. I modded my nub but the ICS spring is not strong enough to push the nub down :(. Will not adjust hop.....

"I have a flat type bucking in my TM p90, and it is fantastic, these nubs are fantastic, they make it so even the slightest adjustment creates huge differences, and create much better backspin allowing for greater range
