Going in the mail later today.
everything takes time to get it correct, the one in the picture, clipping might depend on the caliber.. you could always make different bore sizes depending on caliber.. I know that it's probably easier to make a one fits all..That one is most likely going to have problems with clipping.
I think I made the bore too tight on it. I got carried away and did not allow room for it to be mounted on a shroud. If it does clip it is possible that the shooter may be able to shoot it clear. I've done that and had no problems after that but if it clips on the endcap it will be ruined and he will have to return it for a replacement (which is a pain for him)... so don't get in a hurry guys. Still a work in progress next go round...
It should be pretty quiet for it's size IF it doesn't clip.
Keep watching.
