For me, the welded PTR rail was a deal breaker. You can always mount a rail on the Zenith, but removing it from the PTR? Not so much, lol.
If I had known that HK was going to bring out a SP5, I might not have gotten my Z-5RS, but in the end I’m glad I did. It was cheaper, came with more MP5 features like the pushpin lower and proper rear sight, and since I was going to have to add US parts to SBR it, it didn’t feel as bad swapping out parts on a clone as on a real HK. The latter isn’t a consideration for the PTR, but they seem to have a hit and miss reputation, so I never really considered getting one of those.
Do you even HK, Bro?
Well said! I completely agree
