Hello fellow New Yorker. What a C&R liscense is, is a piece of paper, that allows oyu to buy a particular firearm and have it shipped directly to your house. IE if you were to go to Inter-Ordnance, give them a copy of your liscense, and buy a gun, they would then ship it to your house. This get's rid of the middle man so to speak
No C&R
1) order gun
2) drive to gun store where gun was sent
3) fill out gun stores paperwork and background checks
4) Pay for gun plus any fee the gun store tacked on
take your gun home
C&R
1) find gun you like
2) fax copy of Liscense
3) Pay for gun
4) Wait for the big brown UPS truck
Now pretty much the guns you'll be looking for that qualify under C&R are things used in WWII and the like. Mauser, Mosin, Lee-Enfield. These guns can be found in various conditions and are all advertised as decent shooters.
The big thing I like about the C&R is that once you have it, your obligations for the Civilian Marksmanship Program are filled. Which I can't wait for mine because I heard rumors of M1 Carbines
Any questions, just ask, I sent my paperwork in on Saturday and still have some of the info fresh in my head lol
