I wanted to get an opinion on a rifle. I am looking for semi-auto rifle for plinking and well...just to have. I am looking at a SKS or an AK-47 rifle. It is not often that I get to buy a rifle so when the opportunity becomes available I want to make the right decision. What advice can you give on those two choices I have above? Also what are the different types of the above mentioned rifles and pros and cons on both. I have about 300 to 400 to spend on a rifle. Thanks for your opinion.
