I took my ishapore out shooting with surplus Pakisanti 7.62 NATO. The rifle mechanically was fine, but when I took her apart for cleaning the forend repairs all had failed. Looking closer, the forend on this rifle is so darn loose I can slide it forwards and backwards 5 mm from the rear of the receiver. It needs heavy shimming as well as cracks repaired. My question to all is how should I go about this. A fellow on another forum says he can fix the cracks, etc. for $80 including shipping; I can get a replacement forend (this forend's serial number does not match the rifle's numbers) for $40-50 and try shimming it; or I can monkey around with this stock and try to fix it myself. The cracks will only get worse with such a bad fit on the forend to begin with. If I could find a new walnut No. 1 Mk. 3 forend I would get that and shim to fit. Anyhow, all input desired.
