In 2 weeks me and my 556 will be reunited. since im active duty and stationed in kalifornia i had to leave it home. i have been ordering lots of accesories for it and sending em home so its almost got everything. except new handgaurds. it seems there is a fair mix of people who prefer the swat rails and the samsons. just wanted to see the numbers of what people prefer and why. ive heard the samson replaces the top rail on the reciever which sounds like a good idea but not if i have to take it off to remove the gas tube. any way thanks for the advice guys.
