Transformed my ptr rifle - Spuhr Stock Assembly for G3,MP5,HK33/53

I searched and reviewed every M-4 style adapter for the HK G-3 / PTR 91 rifle as I was desperate to find a way to shorten the length of pull on my PTR 91FR. My conclusion was that in the fully closed position the M-4 style adapters do shorten the LOP, but not my much, and in any other position other than fully closed it appears the LOP is right back where you started. I then discovered the Spuhr Stock Assembly which is specifically engineered for the HK G3 / PTR 91 platform and determined that the LOP with the Spuhr Stock is substantially shorter than one could achieve with the M-4 style adapter. Free shipping from OpticsPlanet made the extra investment into the Spuhr Stock over an M-4 style adapter a bit easier and it arrived quickly. Installation was simple on my PTR 91FR and no issues whatsoever came up. Everything fit as it should. The Spuhr Stock exceeded all of my expectations and the extra cost of the Spuhr Stock was well spent. I never thought the recoil was bad to began with, as I read most people do, but this stock does in fact reduce some felt recoil which is something I was not expecting or looking for. I read another review of this stock and the person described this Spuhr Stock as allowing you to get, "nose on the charging handle close" to the rifle and I couldn't agree more. The LOP is now nearly the same as my AR/M-4.
