Valdada or IOR scopes are pretty high dollar and will stand up to the recoil of a 50bmg, but I seem to remember some reviews about NC Stars not holding zero or having the reticle shift after a few rounds on a 50(don't hold me to that).

A lot of people swear by Super Sniper scopes on 50's, not sure what you consider long range but they come in 10x,16x, or 20x fixed powers for like $300 and are will hold together on the BMG. They would defiantly make a great starter scope for your rifle

The gun has to be single shot, exposed hammer, and the patent has to be from before 1900, the caliber was anything above .38, ms has included 35 but I'm not to up to date on my la laws

With your budget you need to be looking at H&R handy rifles

Class 3 weapons and concealed carry permits are two totally different beasts but yes LA is a NFA friendly state, you just have to register with the ATF and get a tax stamp for each weapon/suppressor

There are a few different ways to get your stamp but the most common is to fill out the appropriate forms, get the local sheriff to fill out a form, have your finger prints taken, and get a passport picture of yourself...once all that is done you send the packet and a $5 check for AOWS (or a $200 check for SBRs SBSs MGs and suppressors etc) and wait about 3-6 months

mind you this all has to be done after you order the gun through a class three dealer, once he gets the gun and knows the serial number all forms can be sent and the wait for the stamp begins... but be careful stamp collecting is addictive
