accuracy difference on reciever\handguard interface

[cst]

The mkm is esentially a monolithic in concept.....the barrel nut holds the barrel on...the handguard is attached directly to the receiver and does not
load the barrel.
Also.....its not just about mounting an optic on the rail but the bipod or the pressure from resting the rifle on a sandbag or barracade etc....

I personally like the mkm or seekins because I can place pinned gas blocks which u cant on a monolith.
