Catalog? Taking it old school huh?
Honestly alot of gun companies and accessory type stores seem to have gone to online only. I cannot remember who it was, but I was placing an order with them and they asked if I wanted a catalog, I was about to click yes when it said it would add $3 to my order.
Save a tree and look online. Between the manufacturer's website and some of the huge sellers like buds and bass pro, even youtube, etc you are likely to learn more about it then the manufacturer would have put in the catalog. Also you would likely get to see reviews and maybe even videos of it. Some probably will only hurt your head but others will be useful.
Plus the online catalog can be updated instantly.
