I am looking to order a LAR-458 from Rock River Firearms in IL. Any firearm I own has been bought from a retailer where I went to the store and paid for it and left with the gun. this is the link to Rock River Arms page with the .458 rifle. http://www.rockriverarms.com/index.cfm?fuseaction=category.display&category_id=251 Indiana has made the .458 rifle legal for deer season. 1. Is it legal to buy this via the internet and have it shipped to the house? 2. If so, what documents would I have to show to make the purchase. Thanks!
