Hey guys, I am now a proud new owner of an M&p 15 16" barrel, no sights, plain ol' rifle. I want to deck it out and have ansome looking/performing rifle! I just have a few questions if you do not mind. I was wondering what sights are good to get? What carry handle? Bipod? Front grip? I have physical limitations, so i must rely on bench shooting now. I have been noticing that there are two kinds of quad rails. Free floating and 2-piece. Which is better/recommended?How long of a rail to use with bipod and front grip? Are the ones on Amazon any good? I would really love any help guys, I am very sorry for asking so much. I just want a great gun and this is the first site I have found. Please help with set ups and accessories I should look into. I would love to have a great shooter, but to also look like a Law enforcement/military rifle. Look forward to input guys. Thanks in advance!! Can't wait to hear what advice and accessories you can share with this eager newbie. I look forward to any advice, tips, or recommendations of parts. I have orseder a few things, but i will wait to install until i hear from the more experienced M&P 15 owners. I would really love any input.
