The buttstock is from highplainsgunstocks.com
The forend is from Dave Dolin, who posts as Dave D here and on SP. He is an incredible stock maker. I told him what I had and wanted to know if he could make something that would go with the buttstock. Without ever seeing the stock in person, that is what he came up with. I LOVE that forend. The HP forend was fine, but the one by Dave fits me perfectly and is heavier than normal, also something I prefer. He can make them any way you like and is very reasonable, too -- and really not much more than a factory forend.
Here is another setup by High Plains. THis one is called Pegasus Thumbhole. I have one on a 30-30 AI and also on a 7mm Bullberry. For me, they handle exceptionally well. I will mention, though, that a member here on GBO recently had a bad experience with the customer service of HP. I have dealt with him 5 times, and all have been perfect, but since this was recent, I thought it warrants mentioning.
