RE: G5 Meta peep
They had some issues with the 1/4" ovaling that supposedly has been corrected. Some of the problem was the design and some of it was tying the serving too close to the peep.
I had one oval and was sent a replacement that isstill in the pack. Bought a Fletcher while I was waiting for the G5 to come back and haven't swapped them out. I'll put the G5 on my next string.
