I got a 14.5 M4 with a per. vortex from model 1 sales and sent it back becouse the front sight is leaning to the right when firing.they told me they saw it leaning but it shoots straight so i asked to be sent another one anyway they later told me that others they checked appeared the same.they said they would send a different one anyway when i got the "different one" it was the same one i sent in i made a mark to tell before sending back.my ? is do i need to send it back again or if it shoots fine could the flattop be the problem? is this a common problem?also i have a vltor casv-el handguard and where it meets the front sight where the sight post meets it it is not centered on the rail it is off center. i just hate putting $1600 into a gun and it not being RIGHT!

Send it back for another one,or send it back for money back so you can buy a diffrent brand!!!
