I ordered a Mannlicher forend and walnut stock from GSI a couple months ago and finally finished the project. The forend required some sanding and bedding, and then I floated the barrel to a dollar bill thickness. The buttstock is similar to a standard Monte Carlo, but I removed some wood around the handle to make it thinner and cut in a cheek piece on one side (for looks). I didn't do a roll-over on the other side in case a lefty friend asks to borrow it. I use a thin strip out of a bicycle inner tube as the barrel band, but it's not in the picture. The scope is a Bushnell Firefly 3x9x40 with Leupold Rifleman medium rings. I had to bob the hammer a bit, but the scope sits nice and low.
I finished the stock the same way as my spearguns, with West Systems 207 epoxy, then 0000 steel wool to break the gloss, and finally a coat of oil on top. BTW, I was very pleased with the service and parts from GSI. The fiull-length forend took most of the effort, the stock was very easy by comparison.
The rifle shoots pretty well with cheap Remington and Winchester 180 gr ammo, I was getting about 1.5" groups at 100 yards. The Winchester printed 4" higher and 1" left of the Remington PSP. I'm going to try the Lapua Naturalis next, seeing as I'm close to the condor area and may need to shoot lead-free from time to time. A friend is going to help me reload, so I'm mostly shooting the factory stuff for the brass at this point.
My next project is fitting up a Tracker 2 barrel to the same action, I'll have to use a standard forend tho. The 12g barrel fit is a little sloppy, so I'll be experimenting with shimming techniques in the wonderful FAQ.
Edit: In case anyone is wondering, the walnut stock is a bit heavier, my rifle and scope come in at 8.5 lbs. The weight and the limbsaver make it a fairly comfortable rifle to shoot.
