Are there pins to drift out that may be holding the barrel in the stock? Look on the for arm and see. I don't own one of these so I don't know. Why are you taking the barrel out?
Just take the lock off and use a flush tube instead.Drifting those pins out will up the chance of messing up the wood on the forestock. Some of those pins hold the barrel to the stock, and some of them probably hold the thimbles to the stock.
I keep a piece of styrofoam on the bench marked so the pins all go back into the right holes they easily push in and pull out of that suff.
