Hi Matt,
Where do you shoot at?
A few things about your enfield, You most likely have a cut down military barrel. Original military barrels were not free floated and usually do not benefit from free floating. Make sure your forestock is tight to the action and barrel.
Your action has a lot of metal removed from it, it may be flexing.
If you need any help fitting a new barrel or installing a new one let me know. I have all the proper tools.
