Thanks you all- First off my compact handguards/forends were installed by a gunsmith (I'm disabled, a wheelchair shooter and the left side of my body works poorly...) one of the compact forenends came apart at the range last week which soured me on them. Much too hard to put back together. So I want to go back to original configuration on both. Can any of the kind and generous forum users give me a rundown on the procedure w/tip, suggestions and warnings? I would be quite indebted. Thank you
