This is an all German HK51A3 IB date code Vollmer conversion with paddle mag release.
Purchased this with a sear, but decided against keeping the host. It is a Vollmer Conversion HK51A3 on a hard to find HK91. This is not a SAR or a clone, but true HK conversion and in amazing shape. Owner said to have put 1 mag (20 rounds) through it after the conversion.
It was married to the sear, so to be able to separate, send to Gerard Miller (HK Smith) to have a barrel extension added to bring up to 16" (title 1). (P/W). Letter of Divorce (saying basically this gun was brought to title 1 length was sent to ATF, letting them know it is above 16"), copy provided to the buyer.. Perfect to have as SBR, sear host, or as it sits.
This is as clean as they come, I just have a G3k clone and no need for (2) .308 guns. SEF Lower with Semi Trigger pack (functions as Safe, Semi, Semi). Would make a great sear host. Includes Vollmer Flash hider as well, if you decide to SBR it to take back to SBR it (cant make it as a pistol, since it started it's life as an HK91).
This is an amazing collectors piece - $3500 , $25 shipping from my FFL.
Plenty of other pics. Comes comes with a few HK mags, steel and aluminum (where legal) Shown before extension added with the included flash hider, bottom pics show the extension added (current state)
