H&K Retractable Stock Fitment Question

[Dynamis]

Do you guys think that this stock will fit my PTR-91 SBR?

One would assume.....

 

[Dynamis]

Just figured it out. PTR and PTR PDW recoil assemblies are different, dammit.

Should be able to swap the buffer springs and stuff? I know you can on standard furniture.

It's a pain to swap all the recoil stuff. I bought an OEM HK91 retractable for my vector 51 sbr. Took it to a machinist buddy and had him swap it over. Looks factory. Didn't feel like doing it myself.
