A carbine buffer in a rifle extension tube will usually result in damage to the lower receiver. You will have too much rearward travel of the carrier, beyond the design limitations of intended carrier travel. The buffer is meant to kiss the rear of the extension to reverse the inertia and provide enough forward momentum to strip the next round and chamber it fully.
The way that this particular handguard clamps to the barrel nut is not conducive to a solid mating to where one would bridge their scope over. The G forces under recoil are substantial, and will find the weak point. This is why optics and mount manufacturers recommend against mounting in this method.
Without purchasing another cantilever scope mount, you could try extending your adjustable butt plate on the PRS, then moving the rings and scope back until you have the forward scope ring on the upper completely.
Were you using the monopod in the rear when shooting those groups? You might consider trying a rear bag if that was the case.
