I am doing a bullpup project, and am hung up my one thing.

I need the Handguard retainer to be rock solid with no movement.
I first thought of just slightly sliding it back which I have room, and making a new indentation in the barrel just deep enough so I can use a tension pin thus making it solid. I have allready removed the lever which use to hold it in place. so I can see the topp part of the barrel.
But I can't get the perfect half moon to be assured of a tight pinned grip.

I can't weld because it is in the middle of the barrel and will no doubt warp it.

Now I am thinking of trying to wrap that area with a shim, but would have to cut the shim in the two areas where the indents are for the inner h/g guides. Then press it on.

Got any suggestions. ???????????????

Could you make a shim to go between the hanguard and retainer?

Thanks for the reply bullet.
I found some super thin shim's and pressed it on then pinned it. She is solid now.
