Yer gonna make me go look, don't think mine has but it's pretty old.
Mines at the cabin but I'll get a pic of it broken down. It's probably 12+ years old I'd say. I think the manual says to just knock back pin out and pivot it apart to wipe clean and oil. I could be wrong but seems like it's built altogether different than an AR, just looks like one. Been a great plinker regardless
