Earl,
Yes, the triggerguard has to com off. The barrels come off as well. Then look down in the reciever where the barrels fit, and depress the bar in the bottom while pushing the toplever to the right, hold the bar down and let the toplever move to the center. Then back the drawbolt in the back of the stock off a couple turns. Give the screwdriver, that you have in the stock to reach the drawbolt, a sharp whack with your palm or a mallet. You should see the reciever move forward a fraction of an inch. Loosen the drawbolt another turn and whack it with your palm and move the reciever a bit further. Finally, back the drawbolt completely out and pull the reciever off the stock.
