I ordered the 28/80 LP from hkparts and it has different markings on it vs the website. When I tried to put it into the bolt head on my PTR 9KT the tapered end that slides inside the bolt head was too thick! I am now concerned that I either got the incorrect LP (I thought they didn’t make 28/80 for full-size) or that my PTR bolt head is wonky and out of spec. A pic of the LP below.
