Rockfist, if it had replaceable "panels" on each side and had no iron sights, it was probably a 77/22 bolt action. I may be wrong, but I've never seen a standard 10/22 with no sights or those panels on it. Both the 10/22 and 77/22 use the same 10-shot rotary magazine. I'm sorry to hear about the fire, but it shouldn't be too hard to replace it. Good luck.
