So I've always wanted an HK91. A real one. I had a PTR91 many years ago with all the fixings, B&T foregrip, the HK bipod foregrip, a pile of mags, Springfield Trigger pack, PRS Stock with enhanced buffer, etc. etc. but it never quite satisfied whatever itch I was looking to scratch. So I ended up selling the rifle and most of the parts on here back in the day. But, I always told myself that if I was in a position to pick up a real HK91 I'd get one.
Fast forward some 8 years and low and behold I come across what looks to be a really pristine non-SBR HK51 conversion for a reasonable price. I pull the trigger and it arrives in excellent condition exactly as advertised. Besides some very minor paint scuffs and a tiny bit of roller dents (you can barely feel them on the inside of the receiver) the rifle looks in really good shape for being an IK date code (1989) with a fluted and ported HK factory barrel from 1995.
So I do the thing where I throw on all the stuff I want on it. B&T hand guard, TA55A Acog, and also a new Magpul PRS stock, which is when I realize the bolt assembly and recoil assembly are a bit weird. It has a chopped down bolt carrier and an elongated recoil handle locking piece. The gun cycles very nicely with its A3 stock and shortened recoil rod, but it was obviously purposely created for the rifle and something like a PTR PDW recoil rod assembly is not going to work.
So I chat with Jeff (ghilliebear) on the forums here because I reckon I should have it modernized to fit a PTR PDW bolt assembly and recoil assembly so I can go shoot it and have parts available in case of anything breaking. After some measuring on my side I realize it would require quite a bit of invasive work on the rifle since the locking handle j-cut is just a little too far back for the PTR PDW collapsible recoil rod to physically function, so we either put on a new front end, or do a custom recoil rod and locking piece job (which it already has to begin with).
Then as I'm disassembling the rifle I finally notice it has the Vollmer rollmark under the trigger assembly, and after some more research I realize that their HK51 conversions have a ton of history on them and are pretty sought after by folks into HK51 firebreathers. Mine being a bit unique because it's still in a rifle configuration.
So after much back and forth, I decided I will just store the rifle in its original configuration for now and leave it alone. There's obviously not gonna be any more of them, and me having the original work changed seems like something I'd regret down the road.
What would you do?
