There is a small door leading to the hopper on the top of the scope, just fill that up.
Actually, its a gravity fed rifle and it the hopper can hold 500 bbs in the hopper, and it fires around 275 fps.
in the scope its a slide on the top put the scope on the gun aligned with the hole in the gun and scope then pour bbs into the scope
any its not about the weight but the caliber. all airsoft bbs are the same diameter unless theyre a crappy off brand but a .12 gram will shoot out of a gun just as a .52 gram will. but dont use either one in an r73. idk your fps but .20 gram or .25 is probably the best
The gun comes with one.
Apparently Not. See the link below.
no.
If you have a local hobby shop, from there. Otherwise, you will have to ship it in.
never use .12 bbs. they are very inaccurate. Buy some .20 tsd tactical bbs, never use crosman
No.
See the link below for the owners manual
That is a question that has a 50/50 chance of each. You would have to state why and what you would be using that for.
Yes, if you shoot the dogs or let them eat the BBs.
