Loose Forend.

[Heff]

My SBT had a small piece of black electric tape in the forend when I bought it, I thought it odd so I took it out. When I did there was a very small amount of movement, so is imply put it back in. I've probably shot a couple thousand round through it since then with no issues.

This is a very common condition with Parker SBT guns. Both of the guns I now own or have owned had a bit of a loose forend. I think its more due to wood shrinkage than anything else.

Make sure the 3 screws on the underside of the forend iron are tight. If they are loose, there will be a gap between the barrel and the end of the forend. Chad and Dave, this may solve your problem.

Thanks Chuck, But I check them regularly. If they become loose the forend develops those nasty little cracks where the wood contacts the iron.
