First I would like to thank Budsgunshop for sending this to me quickly even with the holiday weekend we had. Picked it up at my dealer, and headed home to clean her out. She came fairly oiled. However, I used some shotgun cleaner to blast off the oil/gunk and oiled her up fully myself. Talking off the barrel is extremely easy. You should know the this gun DOES NOT come with the laser/light combo as shown in the picture. Nevertheless, I took her out to the yard and ran some high brass bird and 00 buck. The gun shoots so well and I highly recommend this as a home defense weapon. This shotgun just feels so perfect when you are holding it. It is so well made, down to the safety placement in the center. Very reliable...well all I have to say is: its a Mossberg.. they make fantastic shotguns. Great price, pick one up to defend your house against thieves/hood-rats/zombies ect. Thank you Budsgunshop!
