Barral problem on classic rt

[spectra260]

I bought a classic rt a while ago and the stock barral gos in fine and locks but it came with a boomstick and I cant seem to lock it in. The only way I can even put it in is by unscrewing the pinlock screw above the trigger. It seems the pin wont go over the lil bump on the barral to lock inplace.

How can I fix this?

The dimple where the twist lock sits to keep the barrel from turning is probably not deep enough. I've seen this on a few barrels. You can drill it a little deeper to help lock the barrel in place.

try drilling the dimple a tad bigger, or tighten the barrel twist lock assembly on the gun. The piece that goes into the barrel, has a small allen screw on the bottom of it, screw it in to make more spring tension.
