I got in my G3 heavy buffer and was checking out how to install it on my HK91 stock. First, the buffer hole in the steel end cap needs to be enlarged slightly. No problem, dremel to the rescue.  Second, there is a loose plastic tube inside the stock which is tightened to the old buffer by a screw from the back. I think this adds some rigidity to the assembly. However, the heavy buffer appears to be of the same outer diameter as this tube, and they will not coexist in the stock. My question is: Is this plastic tube just cut up and removed? On a factory heavy buffer installation, are there any other plastic parts in the stock other than the nub on the end of the heavy buffer? My first inclination is just the cut up the plastic insert and march on, but I thought I'd ask... |

You may be in for a bit more work than you bargined for. Here's what Jason @ IGF told me when I asked him about installing a heavy buffer in my gun. "Most standard stock tubes wont fit the G3 heavy. If you really had to you could cram the G3 heavy into a standard stock, but it wouldnt be the best idea. If you want the G3 heavy I'd recommend picking up a G3SG1 buttstock that already had one in it, also a lot of the Hk 91s came with the heavys as well." YMMV |

I guess the problem is that there are variations in the stocks of which I know little about. The front hole in the plastic stock is exactly the right size to fit the heavy buffer. The problem is that there is a plastic insert within the stock that necks down the hole and fills in the void to accomodate the small standard buffer. The insert is loose when not tightened to the small buffer, but the stock pins prevent it from being removed. I think I lucked out in that all I have to do is remove the insert, but I have to destroy it to do so. I suppose I'm really looking for some info on what the interior of a G3SG1 buttstock looks like... Anybody have one? |

I can't really help with the SG-1 stock pics,but I can help find a home for your buffer. If you have another ,or Know where to get one please IM me . If you decide not to use that one ,I'll gladly buy it from you. I've really been looking for the MSG-90 Buffer, but I'll take what I can get right now. My source (Gordon Miller) dried up .

Well...No suggestions so I got to work. Using a chisel heated with a propane torch, I had an impromptu hot knife which I used to cut up and remove the plastic insert in the buttstock. Just be careful about bumping into the stock itself!  I attacked the hole in the metal buttstock cap with a dremel to accomodate the larger diameter heavy buffer. At this point, everything just dropped in! The larger diameter buffer fits snugly in the upper recess of the stock. |
