Alright tell me again. If i mount a scope on my AR15 and one ring is on the receiver while the other ring is on the handguard, will it cause cancer?

Any micron of change between your reciever and handguard will change your point of impact a long distance.

so even if the handguard is locktighted, rocksetted, pinned, torqued to an ungodly amount I would still be screwed????

then explain why guys are using one piece mounts on lmt mrp's.

Preference?

Using a monolithic forearm such as a DD Lite, Troy, MI or Samson and mounting the forward ring at the first notch after the receiver, I would highly doubt there would be that much deterioration in accuracy. If the flex of the forearm was that noticeable to cause disturbances in accuracy, then any rail mount BUIS would be useless considering it is located at the farthest end of the rail which will have the most flex.

and what about bridging the gap WITH a one piece mount?i know it sounds wierd but what if I need that extra eye relief going from rifle to rifle? and don't say spr-e I know that already.

I'm just saying.

Depend in the rail system you are using as the lock ring will most likely be in the way.

By no means am I an expert but here is what I know:

With a free floated and well attached handguard there shouldn't be much issue.

However to reduce risk of potential movement and to keep zero and consistent POI using the pictured Larue mount or mounts that keep the scope only on the upper is best.

YMMV.

Read through the following thread, the author tried bridging across the reciever to the free floater tube rail with a L/T SPR-E mount and started stringing shots horizontaly.
