If the handguard is freefloated, and not touching the barrel, how does it affect the harmonics in a non-neglible way? I.E. The Mega MKM design, or the Seekins receivers where the handguard is attached to an extrusion on the receiver, and doesn't come into direct contact with the barrel or nut.
Now, mind you, this next bit is not an attempt to trample on your hopes and dreams, I'm just trying to have a discussion.
Analytically, I don't see why this type of accuracy wouldn't be possible from an AR, in slow fire anyway. I've seen AR receivers purpose built for accuracy, extra thick walls to increase stiffness, tolerances held to exacting standards, etc... Though I suppose an AR chamber has to be somewhat looser than a bolt gun chamber, to allow for the increased velocity and force that the round is chambered with.
I've never compared chamber dimensions on match grade barrels for either purpose, so if anyone has FIRST HAND knowledge, please weigh in.
But, and this is just curiousity, why the drive to do this in a gas gun? If you're going for high accuracy in a slow-fire situation, aren't you losing the main benefit of the AR platform, i.e. rapid fire and magazine capacity?
At that point, wouldn't it be easier to cut bottom metal so it could feed a bolt gun from a high cap AR mag instead?
Either way, it seems like an interest proposition you've got there, I'd like to hear back on the results.
