Bought my son a Browning Gold 12ga used. At some point the walnut foregrip has split but is still in 1 piece. I dont want it to split the rest of the way. I was told there is a fiberglass kit I can use on the inside of the foregrip. Can someone tell me what its called or even provide the link on Midway or Brownells. All I can find are glass bedding kits.
