There is only ONE option for the AR15 sniper rifle. The flat top upper receiver. You can not beat the versatility as it will allow a variety of options. The standard A1 or A2 upper can be used effectively, but they are hardly ideal. They force you to mount the scope up to 4 inches over the centerline of the bore and getting a good cheek weld is next to impossible without the assistance of a separate cheek piece. The height of the scope over the bore is the biggest downside. This can cause some interesting problems if you cant the rifle to one side or another. With the flat top receiver you will mount the scope low enough to avoid this potential nightmare but you will still need to keep the scope high enough for proper cheek weld and sight picture. This will require either high or extra high scope rings or a small riser device that elevates the scope (with standard rings) to the proper height. Mounting low rings directly to the flat top upper will force you do drop you head sideways over the buttstock. This is hardly comfortable or conducive to precision shooting. The riser device will cost you about $40. There are cheaper ones on the market. But you have to check quality. The riser clamps onto the flat top and the scope rings clamp onto the riser. GG&G offers top notch risers in the hundreds of dollar range. You'll have to research what is available and decide what fits your actual needs
