I have bought a smith and wesson M&P 15 sport a while back and i am thinking of upgrading my upper receiver. I was wondering if i could simply buy one like this http://www.bravocompanyusa.com/Upper-Receiver-Assembly-M4-Flat-Top-demo-p/flat%20top%20-upper%20-m4%20demo.htm and then take it to a local gunsmith to have uppers swapped. I am trying to save money here and upgrade to an upper with dust cover and forward assist. i dont have much experience with switching out parts like this. Also i wanted to know if i used this upper will it fit properly and not look sloppy. Thanks
